HOMOLOGY. Is it proof of Evolution or by design?

Question

Briefly homology is the observation ( made by biologists) about vertebrate limbs showing similarities in their bone structures. Or, take the opposable thumb. Monkeys have it and humans have it. Therefore, some would argue, that man evolve from monkeys

Answer 1

Thanks,
But that observation is called “Bera’s Blunder”. Tim Bera, by the way was a biologist and author of the book: 1990 book, Evolution and the Myth of Creationism. Law professor (and critic of Darwinism) Phillip E. Johnson dubbed this : “Berra’s Blunder.”

Berra forgot to consider a crucial, and obvious, point: Corvettes, so far as anyone has yet been able to determine, don’t give birth to little Corvettes. They, like all automobiles, are designed by people working for auto companies. In other words, an outside intelligence. So although Berra believed he was supporting Darwinian evolution rather than the pre-Darwinian explanation, he unwittingly showed that the fossil evidence is compatible with either.
The lesson of Berra’s Blunder is that we need to specify a natural mechanism before we can scientifically exclude designed construction as the cause of homology.

BTW, Don, logic is on the side of design /creation. Try to beat this one
Premise(1) For every rule there is an exception
Premise (2) Everyday things--TV, computers--are less complex than natural things like the universe, our eyes. Further if less complex things have makers, then the more complex ones has /have makers.
Premise 3. The grand Designer /Maker is the exception to the rule.
Conclusion: Therefore, everything has a maker except the Grand Designer/ Maker.

Answer 2

No. NO-ONE with ANY scientific background would ever suggest that humans evolved from monkeys. That absurd idea is mentioned only by religious fundamentalists who would like to invalidate the findings of science. Scientists however WOULD agree that such homology, in many cases (though not all), provides evidence of common ancestry between monkeys and humans, which is to say that both lines arose from some earlier line that was certainly not a human and certainly not a monkey.

Incidentally, the fact that both lines arose through biological evolution doesn't say anything one way or the other about the question of design. That is a theological question. Evolution is a biological question. Scientists simply seek answers to the question "what happened?", and "how did it happen?", in natural terms. They don't address the question "who made it happen", or "who designed the system?", because they are not theologians. However, scientists who are believers, and there are many of us, know the answer to that question as well.

Answer 3

*rubs his forehead*

Science... does not deal... with PROOF. PERIOD. End of discussion.

Science CANNOT prove ANYTHING. Science cannot PROVE evolution. It cannot PROVE gravity. It cannot PROVE that if you fill a balloon with 2 parts hydrogen and one part oxygen STP and hold it over a flame, you will get a huge BOOM and the creation of one part water.

Science deals with EVIDENCE. Homology is one of MANY evidences in favor of evolution. So far there is no evidence against evolution. That does NOT mean there is no such evidence, just that we haven't found any yet.

There may very well be a region in space where the laws of science are so significantly different that the balloon mentioned above would instead produce half a part hydrogen peroxide and leave a part of hydrogen, all happening with a quiet whimper. We don't know if there is or not. BUT, every single time we've done the 2 * H2 + 1 * O2 experiment, we've gotten BIG BOOM and water. So we consider this the rule. We can never rule out 100% the exception to the rule.

Answer 4

Man and monkeys evolved from Carpolestes, a small tree-dwelling, fruit eating creature with grasping digits. Homology tends to go against design. Using the same structures for upright-walking humans as four-legged creatures explains back and knee problems but doesn't suggest design.

Answer 5

These mutations are not really very frequent, and when they become somewhat unduly accumulated, they tend to speciate or diverge into a completely different species or morph. The chimp and human gene pool diverged millions of years ago, and over those millenia, both populations accumulated mutations that diverged each one respectively from their common ancestor gene pool, resulting in the two different species we have today. The small differences are obviously is due to the relatively short period of time since they speciated. Structuraly both species are similar, having hands that are common to most monkeys and primates. The chimpanzee though has a somewhat more clumsy and rudimentary clutch when found to a human's. It also has a banal walk, as it does not stand on two legs and uses it's forearms in what is called a knuckle walk. Zoning into being adapt, a chimp is suave at tree climbing, which a human, although is capable of doing so, is not adapt at. The most significant differences though, happen to be in mutations of control or master genes which switch on DNA segments while the organism is developing. Mutations in these genes cause great differences in the developed organism. For instance there are 18 differences a certain master gene between man and chimpanzee while in that same gene, there are only 2 differences between a chimpanzee and a chicken. These differences although quite turgid, are not considered lofty enough to be vividly different.

Answer 6

Homology is a huge indicator for evolution. The fact that we share the same basic set of bones with cats, dogs, dolphins and just about every other mammal shows that we started with some common template.

Answer 7

A shark has eyes, so does a fly, and a mouse. A Ford Tarus has a battery, so does a Honda Civic, and a Boing 747. A cup of coffee is nearly 100% water, so is a Coke and a cloud. Which one evolved from the other one.

Answer 8

I'd say it's proof of evolution. If God made everything and is all-powerful, mammals would not need a similar bone structure to each other. However, equally, God could make things similarly. There's no reason why he'd HAVE to make them different.

Answer 9

Hmm... I think I see where your going. but you're going to have to find something more specific.

Things we share with other animals.....
brains, lungs, nerves, livers, colons, stomachs....you see where I'm going.

I could say that genetically, we are closer to the Ape then other animals, but if we evolved from them, I'll let the professionals decide.

Answer 10

Watch out for false prophets... You will know the tree by its fruit. A good tree bears good fruits. A bad tree bears bad fruits.'

we have seen Htler,bush so and so on ,so we know about the bad fruits....
