Because they don’t eat chickens. snert
We have a great many ancestors that were monkeys. I would guess that humans have at least a dozen monkey ancestors.
It’s perfectly correct to say that humans evolved from monkeys.
Wow, this is deep. I think it may cause the whole evolutionist crowd to re-think their beliefs. I’m not sure if they have a thesis for this. Cause if they did, it’d probably be one of the first things explained in any description of evolution. It’d be the kind of thing that anyone with any rudimentary knowledge of logic or biology would know.
Dan, there are many unanswered questions about this that do not have an adequate explanation in current science. Any researcher who finds out how species can pass on different characteristics to their offspring based on selective pressure will surely win a Nobel Prize.
We’ll call it ‘Darwingate’, and scream fraud when google ignores our creative speeling.
I’m not sure why this wasn’t in GQ in the first place.
Well then, explain the short black people that forage the jungle deep in Africa.
Why are there still bacteria and plants? In fact, the main part of life is bacteria and plants. We are just parasites on that basic foundation of life.
Well, “has it” depends on what Terraplane intended to mean. If the intent was a complete aside – “by the way, unrelated to evolution, our common ancestor didn’t persist into modern times” then it’s technically correct but does not address the OP.
If the intent was “because the common ancestor turned into humans and chimps and was no longer itself,” that’s flat-out wrong. As would be “Humans and chimps better suited the environment and lived, while the common ancestor necessarily died out, being an older form.”
Evolution does not change one species into another, it (sometimes) changes a population of that species into another, often leaving the original species intact. Evolution does not move in a direction toward improved forms; instead, accident and chance pick off some forms while leaving others behind. This tends to select for traits fitting the current environment but does not imply a better form the next time environmental conditions change.
Species split into populations, subspecies, and new species all the time. The “old” species can co-exist with the new subspecies or species until fate causes further changes, up to and including wiping out one or both of the now-different forms.
If the common ancestor evolving into humans and chimps meant there were no more of the common ancestor, we wouldn’t still have wolves and:

The reason we don’t have the common ancestor any more is unknown and probably unknowable – it just happened that they perished and we didn’t. But that’s not true for dogs, as you can see, or for many other species.
What needs explaining?
I think I could mate with one of those.

Apes are our evolutionary relatives, not our evolutionary parents. Our mommys and daddys are dead, but our cousins and nephews are still alive.
Anyway, as others have said, the important thing to understand is that evolution is a local phenomenon. Let’s say there’s a big group of some animal. While foraging, half of them cross a ford over a river into a rocky area, while the rest stay closer to home, which is more forested. Then there’s an earthquake and the river’s impassable. These two groups now live in different conditions – one in forest, one in rock. The things there to eat are different. The shade is different, and therefore means of temperature control. The footing is different. So if the rocky group evolves over time to meet these new challenges, it’ll be very different than the other group. But they’ll both still exist, because they both have adapted to suit their current environments. Until such time as something else changes and they either adapt again, or die out.
Which one? Is she the gorilla your dreams?
Yes, that’s it, but delete the “probably” from your second sentence. Also, apes split off from monkeys a lot more than 3M years ago. Multiply that by 10.
While the genus *Homo *probably evolved on the grassy plains of Africa (~2M years ago), our earlies ancestors who walked upright probably didn’t. The more common hypothesis these days is that we’ve been walking upright for at least 4M years, and probably even longer. At that time, our ancestors were likely living in a mixed environment of woodlands and grass and were still adapted to spending a significant amount of time in the trees.
A nitpick, maybe…but if you are saying that species always get highly modified over time, I don’t think that is certain. Crocodiles and coelacanths (for example) are considered to be nearly identical to their long ago ancestors.
Note the 4 words immediately after “probably” in that post. No nitpick required.
