Incomplete lineage sorting

[BarryDesborough]

A tiny bit of knowledge is a dangerous thing.

Good news! The gorilla genome sequence was published in Nature last week, and adds to our body of knowledge about primate evolution. Here’s the abstract:

Gorillas are humans’ closest living relatives after chimpanzees, and are of comparable importance for the study of human origins and evolution. Here we present the assembly and analysis of a genome sequence for the western lowland gorilla, and compare the whole genomes of all extant great ape genera. We propose a synthesis of genetic and fossil evidence consistent with placing the human–chimpanzee and human–chimpanzee–gorilla speciation events at approximately 6 and 10 million years ago. In 30% of the genome, gorilla is closer to human or chimpanzee than the latter are to each other; this is rarer around coding genes, indicating pervasive selection throughout great ape evolution, and has functional consequences in gene expression. A comparison of protein coding genes reveals approximately 500 genes showing accelerated evolution on each of the gorilla, human and chimpanzee lineages, and evidence for parallel acceleration, particularly of genes involved in hearing. We also compare the western and eastern gorilla species, estimating an average sequence divergence time 1.75 million years ago, but with evidence for more recent genetic exchange and a population bottleneck in the eastern species. The use of the genome sequence in these and future analyses will promote a deeper understanding of great ape biology and evolution.

I’ve highlighted one phrase in that abstract because, surprise surprise, creationists read the paper and that was the only thing they saw, and in either dumb incomprehension or malicious distortion, took an article titled “Insights into hominid evolution from the gorilla genome sequence” and twisted it into a bumbling mess of lies titled “Gorilla Genome Is Bad News for Evolution”. They treat a phenomenon called Incomplete Lineage Sorting (ILS) as an obstacle to evolution rather than an expected outcome.

Do they know which ethnic group is more chimpanzee then human?

Do they know which ethnic group is more chimpanzee then human?

You do realize ethnic groups aren't different species, right?...

That by itself doesn't answer the question; some ethnic groups are more closely related to Neandertals than others, after all. But no, there's no reason to think any ethnic group is closer to chimpanzee than any other.

How so? They assume man came from monkey.

Monkey's have many different species, why would evolution cause us to change the word species to ethnic group?

Every time a chimpanzee has a offspring it always resembles a chimpanzee. If a Neanderthal came from a chimpanzee why are there no more Neanderthals? And since we know the famous chimpanzee from the 70's; that was thought to be a humanzee, was in fact 100% chimp. Why haven't we found out more if the Neanderthal was in fact 100% human.

The first dog was likely a wolf according to science, but that doesn't stop most dogs from breeding other breeds of dogs, yet do we see any apes breeding chimpanzees? Has a Ligger ever been found in the wild or only captivity?

No, they don't.

 

[Bungle_Bear]

You most definitely find Liggers in the wild!

But I suspect you really mean Liger? Unless large felines have started taking blue sky holidays they couldn't exist in the wild.

 

[toolmanjantzi]

No, they don't.

Oh, that's nice.

 

[toolmanjantzi]

Yes, that's what I meant. Autocorrect, gets the blame most of the time, but this time it was me.

Why could they not exist in the wild? Is it due to the offspring being STERILE?

Ethinic groups are not different species. We can all breed together freely. Species can no longer breed due to mis-matched genes or completely incompatible behavior.

Every time a chimpanzee has a offspring it always resembles a chimpanzee. If a Neanderthal came from a chimpanzee why are there no more Neanderthals? And since we know the famous chimpanzee from the 70's; that was thought to be a humanzee, was in fact 100% chimp. Why haven't we found out more if the Neanderthal was in fact 100% human.

All modern people are descended from a single population of creatures we'd call humans.

Some modern populations have a small amount of DNA that is the same as Neanderthal DNA.

This lines up with the ethinic groups that come from parts of the world where Neanderthals used to live. It's not rocket surgery.

The first dog was likely a wolf according to science, but that doesn't stop most dogs from breeding other breeds of dogs, yet do we see any apes breeding chimpanzees? Has a Ligger ever been found in the wild or only captivity?

But after only a few thousand years there are a number of genetic diferences between modern dogs and wolves. Just scale that up over a longer time frame and isolated populations and you can clearly see how this could lead to actual change in species.

That is quite a problem for the procreation, for sure, but ligers are not necessarily sterile though. Liligers are known....

The main reason they don't exist in nature though, is that the habitat of the parent species doesn't overlap. Got to be able to meet to do the deed, you know.....

But a dog and a wolf can still breed. Humans and monkey's can not breed. Let alone the different species of birds can not breed. So, the thoughts of man coming from a chimpanzee is not even possible.

And regardless of ethnicities, there would be a dominant ethnic group.

Maybe Neanderthal are part angel and part human.

Anyone tried?

True. That is what science is saying too.

 

[BarryDesborough]

Do they know which ethnic group is more chimpanzee then human?

As the blog title says, "A little bit of knowledge is a dangerous thing." And lo, we have this question!

In all humans most of their genes will be most closely related to other humans' genes. The nearest equivalent for most of these genes will be found in chimpanzees, but for some genes, the nearest equivalent genes will be found in gorillas, or in orangs.

This would be so for any human of any ethnic group.

Did you miss the part about blue sky holidays? Lions live in Africa, Tigers in Asia. I don't care how big you think a lion's ***** is, 5,000 miles is just too far.

I don't think anyone thinks humans come from chimps... They both come from the same ancestral ape group.

Dogs and wolves have only been separated for a few thousand years... chimps and humans have been separate for millions of years. More differences have racked up.

Check out our close family:

A is a modern chimp B is an Australopithecus. Much closer in structure. If you saw B alive today, you might mistake her for a chimp till you saw that she mostly walked on her hind legs and had what looked like human feet.

Maybe Neanderthal are part angel and part human.

Don't tell the racists that! They'd be heart broken to find that the sons of Shem and Japheth were tainted by the Nephilim and only the sons of Ham were pure.

The theory of evolution does NOT say that man came from a chimpanzee. The theory says that we (humans and chimps) share a common ancestor, e.g., were at one time the same species (neither human nor chimp), but branched off from one another 6 to 10 million years ago and evolved separately. During that time, we (chimps and humans) became no longer sexually compatible. Whether or not they could combine the DNA in a lab and create a living being, I don't know and don't want to know.

Maybe Neanderthal are part angel and part human.

So which part of the neanderthal genome comes from angels?

German researchers publish full Neanderthal genome

Why is it impossible? Please explain. Why can't isolated populations accumulate mutations over time to the point that they can no longer produce hybrid offspring?
