Design flaws in organisms indicate evolution, not intelligent design

[Compassionist]

The existence of design flaws in living organisms is often cited as evidence for evolution by natural selection rather than intelligent design by an all-loving, all-knowing, and all-powerful deity. If such a being existed and created life intentionally, we might expect optimal design yet what we see instead are structures and processes that are inefficient, prone to failure, or even harmful.
Here are some significant biological design flaws that point to evolution rather than perfect design:
________________________________________
1. Human Birth Canal vs. Big Brain
Flaw: Human babies have large heads due to our large brains, but the human pelvis is narrow for bipedal walking.
Result: Childbirth is extremely painful and dangerous a leading cause of death historically.
Evolutionary Explanation: Our ancestors evolved larger brains and upright walking separately, leading to a dangerous compromise.
________________________________________
2. Wisdom Teeth
Flaw: Most people don't have room for third molars, causing impaction, infections, and pain.
Result: Many need surgery to remove them.
Evolutionary Explanation: Our ancestors had larger jaws due to diet, but modern humans' jaws shrank faster than tooth evolution could keep up.
________________________________________
3. Human Retina Is Backward
Flaw: The photoreceptor cells in the human eye are behind layers of neurons and blood vessels.
Result: Creates a blind spot and reduces image quality.
Evolutionary Explanation: The eye evolved incrementally, not from a clean-slate design.
________________________________________
4. Recurrent Laryngeal Nerve (Giraffe Example)
Flaw: This nerve travels from the brain to the larynx, but loops around the aorta.
Result: In giraffes, it travels over 15 feet instead of a direct path of a few inches.
Evolutionary Explanation: It's a leftover from fish ancestors, where this path made sense. Evolution modified existing structures rather than redesigning from scratch.
________________________________________
5. Human Menstrual Cycle
Flaw: Humans shed the uterine lining even if not pregnant, wasting resources and causing pain.
Result: Menstrual cramps, anemia, mood changes.
Evolutionary Explanation: Other mammals reabsorb the lining. Our approach may have evolved due to pathogen risks in internal fertilization.
________________________________________
6. Shared Path for Food and Air
Flaw: The esophagus (food) and trachea (air) share an entrance.
Result: Risk of choking a leading accidental cause of death.
Evolutionary Explanation: The throat evolved in stages, without foresight.
________________________________________
7. Human Spine and Back Pain
Flaw: Our spine is an S-curve not ideally suited for upright walking.
Result: Many people suffer chronic back pain, herniated discs, etc.
Evolutionary Explanation: Our ancestors were quadrupeds. The upright posture evolved later, leading to inefficient structure.
________________________________________
8. Brain Vulnerability and Mental Illness
Flaw: The brain is highly energy-consuming and prone to many dysfunctions.
Result: High rates of depression, anxiety, bipolar disorder, schizophrenia, etc.
Evolutionary Explanation: Natural selection favored reproductive success, not mental wellness or long-term wellbeing.
________________________________________
9. Knee Joint Design
Flaw: Knees bear immense strain, especially the ACL (anterior cruciate ligament), which often tears.
Result: Common injuries in sports and aging.
Evolutionary Explanation: Knees evolved from quadruped ancestors, not optimally engineered for bipedal running and jumping.
________________________________________
10. Genetic "Junk" and Mutations
Flaw: The genome is full of non-coding or redundant DNA and is prone to harmful mutations.
Result: Genetic diseases, cancer, and congenital defects.
Evolutionary Explanation: DNA accumulates "baggage" over time. There's no intelligent editing or streamlining process.
________________________________________
11. Susceptibility to Cancer
Flaw: Cells divide for life but are prone to mutations that cause cancer.
Result: One of the top global causes of death.
Evolutionary Explanation: Cell division is essential for life, but natural selection can't eliminate all cancer risk especially after reproductive age.
________________________________________
12. Human Psychology Biases
Flaw: We are prone to cognitive biases (e.g., confirmation bias, tribalism, overconfidence).
Result: Misjudgments, discrimination, and conflict.
Evolutionary Explanation: These evolved to enhance survival in specific environments, not to produce truth-seeking rationality.
________________________________________
If we were designed by an omnibenevolent, omniscient, and omnipotent being, such flaws are impossible to justify. Evolution by natural selection, on the other hand, explains these quirks and imperfections as the result of a messy, blind, trial-and-error process where old parts are tweaked, not replaced, and survival/reproduction, not perfection, is the end goal.

The full original title of Charles Darwin's book is: "On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life".

First part is what atheists latch onto, which is why it's most popular: 'Evolutionary origin of the species', is an ideological impossibility. Origin can only be by creation from nothing going before, not by evolution from something coming before...

The 2nd part is the actual proven science of single species evolution, with an observable explanation: Proving what, leads to answering how. And it only applies to animals, not to people, because there is no favored race of man, but only one.

Acts 17:24
God that made the world and all things therein, And hath made of one blood all nations of men for to dwell on all the face of the earth…

All mankind has our own one blood, and animals have their own blood, and they can never intermix and give life. People are not animals in blood nor spirit, and animals are not people.

You don't know why you carry insect dna

DNA is the common element of all flesh on earth, whether of man, beast, or creeping things. But man's one blood is not that of the many animal bloods.

Man is created in God's image of spiritual intelligence. I have no spiritual bug-brothers, nor does a bug have my intelligence. And though some people want to be one with the bugs, they can't, except only in their vain minds:

Rom 1:22
Professing themselves to be wise, they became fools, And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.

and you can't explain tetrapods

When you acknowledge the difference between proven single species evolution, vs unproven evolution between nonbreeding species, or speciation...

In any case, man can explain tetrapods. Tetrapods can't explain anything.

Gen 1:26
And God said, Let us make man in our image, after our likeness: So God created man in his own image, in the image of God created he him; male and female created he them.

but your hubris reigns supreme

Debating you doesn't take pride. In fact, arguing against people being bug brothers and sisters takes putting up with nonsense.

Pro 26:4
Answer not a fool according to his folly, lest thou also be like unto him.

And I would never accuse anyone of hubris, by making bugs their spiritual and mental equals...

"We are different than other species as they are different than us. That said it doesn't mean we are in anyway better mentally.

And calling what you said "intelligently speaking..." doesn't quite fit since it seems obvious you didn't know of our insect spirit brethren."


Once any person purposes to disprove their creation in the image of God, there is no bottoming out. Even if trying to prove it by declaring themselves as spiritual and intelligent as bugs...

The transition from an interbreeding population to a non-interbreeding one is the fundamental driver of evolution, a process known as speciation. This transformation happens in three distinct phases: [1]
1. Interbreeding (The Starting Point)
Populations freely interbreed, allowing a shared gene pool. Genetic changes that arise in a single individual can spread across the entire group over time, keeping the population cohesive and capable of adapting together. [2, 3, 4]
2. The Evolutionary Divergence (The Transition)
As populations are separated—either by geography (e.g., mountains or rivers) or by ecological niches (e.g., feeding in different areas)—they evolve independently. Over generations, they accumulate different genetic mutations, adapt to unique environmental pressures, and experience genetic drift. [1, 5, 6, 7, 8]
3. Non-Interbreeding (The Result)
Eventually, the accumulated differences become so significant that the groups can no longer reproduce to create fertile offspring. This reproductive isolation can take several forms:

• Behavioral: They no longer recognize each other's mating calls or rituals.
• Mechanical: Physical incompatibilities prevent mating.
• Genetic: Mating occurs, but the sperm cannot fertilize the egg, or the offspring is sterile (like a mule). [9, 10]

Once this happens, the two groups become entirely separate species, following completely independent evolutionary paths. For a broader look at how this tree of life branches out, you can explore the Khan Academy Speciation Guide. [2, 11]

Great. You've written out speciation theory. Not speciation proven.

Like abiogenesis and the Big Bang are theories, not proven fact. It's an entire cottage industry inserted into education, that's full of endless theoretical processes without factual proof.

So now we see that speciation between non-breeding species is only theory, while single species evolution is proven fact, for animals. Not for any person on earth: All people are still physically the same since the beginning. Only a species of animal evolves into similar creatures, that are no longer the same, such as the differently evolved primates: ape, monkey, gorilla...

There are no differently evolved men and women, because man is not a species of animal on earth. There is man, and there are animals. There is one man and woman, but there are many species of animals, with their evolutionary divergent subspecies.

[RBD]

Proverbs 6:16
These six things doth the Lord hate: yea, seven are an abomination unto him:

19. A false witness that speaketh lies, and he that soweth discord among brethren.

My arguments have been causing you discord among your bug brothers??

[RBD]

So, what animals other than people, are people too? What animals are not people, other than bugs?

All human beings are people. All people are human beings. I claim both of these as premises.

Great. We agree on something.

Affirming the consequent is of the form:

1. All people are animals.
2. A burrow owl is an animal.
3. Therefore a burrow owl is a person.

Correct. If all people are animals, then all animals are people, including burrow owl animals.

This is affirming the consequent and a logical fallacy.[/quote]

Mute point, with someone agreeing people are only people, and not animals...

All animals are people, but not all people are animals.

This is backwards. All people are animals, but not all animals are people.[/quote]

Oh well, back to the beginning.

Ok, so what animals are people, and what animals are not people?

[RBD]

Which of course is all just evasion nonsense: The declared relationship of noncreation evolutionists, is that all people in body and in spirit are the same as all animals.

No noncreation evolutionists say that, or at least if they do, you and I agree that they're wrong.

Good. I'm corrected. Not all noncreation evolutionists also deny spiritual things.

While ancient pagans are not evolutionists, they did believe in the uncreated spiritual things of all living creatures, where man, bird, or tree. As well as the nonliving things of nature having their own spirits: Stars, planets, air, clouds, and waters...

Modern pagans may be primate-man evolutionists too. And they are the only noncreation evolutionists that have sense enough to know, that without creation, nothing natural, living, and thinking, can have any original beginning: Old pagan universal deism.

People like bugs and burrow owls, are just animals,

Yes.

and animals like bugs and burrow owls are also people too...

No.

Since no animal is a person, no person is an animal. Except in some people's own minds. But no animal thinks that at all...

[RBD]

Things that would falsify evolution:

Thousands of years of live births observed, where animals are observed to produce what they are, not what they aren't.

False. That would only disprove speciation evolution from one interbreeding species to another non breeding species: Fish producing amphibian

Single species evolution is proven: Jawless, cartilage, bony fish...

Things that would falsify evolution:

Thousands of years of live births observed, where animals are observed to produce what they are, not what they aren't.

Proven. In thousands of years no one has observed in life nor in fossil, a fish producing an amphibian.

One thing to prove speciation:

Fish fossil producing amphibian fossil. Including hybrid fossil producing a non hybrid fossil.

[RBD]

Evolution happens to populations, not individuals.

This is the excuse argument for no individual fish fossil never producing an amphibian fossil.

The follow up excuse argument, is that it takes so many millions of years to evolve from a fish to an amphibian, that the missing fossil link between a fish and an amphibian can't be found, yet...

Ok. Unfilled gaps does not disprove speciation theory from one species to another, but it does prove it's still an unproven theory.

Only single species evolution is already proven in fossil detail without missing links.

[Difflugia]

All human beings are people. All people are human beings. I claim both of these as premises.

Great. We agree on something.

Correct. If all people are animals, then all animals are people, including burrow owl animals.

This is affirming the consequent and a logical fallacy.

Mute

Moot

point, with someone agreeing people are only people, and not animals...

I didn't say that. I said that all human beings are people and all people are human beings.
I've also said that all human beings are animals and all people are animals.
Furthermore, not all animals are human beings or people.

Those are all consistent with each other.

All animals are people, but not all people are animals.

This is backwards. All people are animals, but not all animals are people.

Oh well, back to the beginning.

Ok, so what animals are people

Human beings.

and what animals are not people?

The animals that aren't human beings.

[Difflugia]

Which of course is all just evasion nonsense: The declared relationship of noncreation evolutionists, is that all people in body and in spirit are the same as all animals.

No noncreation evolutionists say that, or at least if they do, you and I agree that they're wrong.

Good. I'm corrected. Not all noncreation evolutionists also deny spiritual things.

Where did "spiritual things" come from? It's like every time you're close to getting it, you intentionally throw a curve ball in to make sure that what you're saying is nonsense.

While ancient pagans are not evolutionists, they did believe in the uncreated spiritual things of all living creatures, where man, bird, or tree. As well as the nonliving things of nature having their own spirits: Stars, planets, air, clouds, and waters...

Modern pagans may be primate-man evolutionists too. And they are the only noncreation evolutionists that have sense enough to know, that without creation, nothing natural, living, and thinking, can have any original beginning: Old pagan universal deism.

Whatever. Being right about biology apparently doesn't keep someone from being wrong about gods. There aren't any gods, Christian, pagan, or otherwise. This is similar to your misunderstanding about people and animals: Some theists understand biology, but not everyone that understands biology is a theist.

Since no animal is a person,

Human beings are both people and animals.

no person is an animal.

All people are animals.

Except in some people's own minds. But no animal thinks that at all...

What?

[Carnivalfaces]

Your laymen weakness is showing again. As well as your lack of knowledge. "Speciation" is the term you're looking for.

So, you finally looked it up. It's a start. Speciation is only theoretical, not proven.

Speciation is only what evolutionary ideologues hope to be true, so that can justify not acting like people of God made in His image, but only as another animal on earth:

LOL, you finally looked it up is a more honest statement. You didn't even know "speciation" existed as a term till I informed you. You should read proverbs 16 sometime so your fairytale god won't hate you. It's about telling fabrications like you just did...

Proverbs 16:16-19: 16 These six things doth the Lord hate: yea, seven are an abomination unto him:

17 A proud look, a lying tongue, and hands that shed innocent blood,

18 An heart that deviseth wicked imaginations, feet that be swift in running to mischief,

19 A false witness that speaketh lies, and he that soweth discord among brethren

Jde 1:10
But these speak evil of those things which they know not: but what they know naturally, as brute beasts, in those things they corrupt themselves.

Or, even a bug.

Of which you share dna, fact. Also fact, you have no dna evidence of your god or of its myth book being true.

And again, just because you say "evolutionary origin of species" for self delusional reasons,

Take that up with Darwin and his ideological followers.

Darwin has nothing to do with your misuse of terminology.

it isn't the origin of life.

Of course not. Evolution isn't the origin of anything. Without creation there is no origin, but only everlasting substance, life, and intelligence6h without beginning.

Energy and matter cannot be destroyed. No sign of intelligence from any mythical god creature made up by bronze age goat herders designed to manipulate the gullible has been detected.

That's why Darwin's 'Origin' of the species is his personal ideological insert into proven evolution of the species. It's his theoretical alternative to creation of the species.

You really don't know your bible or science. It tells you it's better to keep silent when stupid on a subject because when you open your mouth you remove all doubt that's the fact, like you've just done.

Proverbs 17:28: 28 Even a fool, when he holdeth his peace, is counted wise: and he that shutteth his lips is esteemed a man of understanding.

Proverbs 12:23: A prudent man conceals knowledge, But the heart of fools proclaims foolishness.

An uncreated evolutionary universe with life and intelligence without origin, is old pagan universalism and deism. They called them the primordial gods, and pseudo-scientists call it soup. Gods without beginning have more intelligence than stupid soup.

What has that to do with reality or the proven fact new species had derived from previous common ancestors through the recombining of the gene pool via evolutionary process, also predicted by Darwin correctly that if it was true the evidence will be found in the fossil records, and was?
