    So perhaps you should add the big-chip Einstein to the other side.. indeed add him to those "nasty, condescending" atheists.
    Here's one more quote.
    It was, of course, a lie what you read about my religious convictions, a lie which is being systematically repeated. I do not believe in a personal God and I have never denied this but have expressed it clearly. If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it.

    The idea that the super-volcano "Toba" caused a near extinction has been getting a bit of popular press lately. There have been some studies that suggest that the total human population might have been at a very low level relatively recently.

    All our closer relatives are extinct. Some species share a lot in common, but slugs, leopards, and giant redwoods are more separate compared to each other, than we are compared to chimps.

    Well, we are smarter than any other thing on the Earth (that's what I like to think at least). Water bears can survive freezing, boiling and the vacuum of space, although technically I don't know if you'd really call that "adaptable" or just "tough".
    Wouldn't an extinction event that affected humans not also affect chimps?

    Chuz, the genetic difference is evidence of part of the process of evolution. If the shift continues far enough and leads to speciation, it would be a complete step in the process of evolution. It seems to me that speciation would be unlikely.
    If we and apes descended from a single ancestor, why are we so less genetically diverse than any of the other three?

    If you mean closest living relative species, I'm pretty sure that Bonobos are less genetically diverse than Humans.




    Again, not sure I follow. Neanderthals weren't very different from modern Humans in mentality and physicality. We know that they buried their dead with flowers and made musical instruments, and physically the biggest dsifference is that we are more gracile.



    We aren't more adaptable to our environment than other species are, we are simply more likely to adapt the environment to suit our needs. Clothing, houses, the use of fire, etc are examples of this adapting the environment.

    As far as inherent adaptabilty goes, it's pretty hard to beat the common rat.
    Yes, I meant extant species. Chimps are far more genetically diverse then humans.

    2. 99.9995% of all scientists accept evolution as fact - and yes, many of these scientists (in fact the majority of them) believe in a god. Evolution doesn't seem to hurt their belief in a higher power, so why does it hurt yours? In my opinion, if God had used evolution to develop all the species over millions of years, that would have shown a lot more creativity on his part, than had he just said "presto!" and made them all appear by magic.

    3. Evolution and the Big Bang theory do NOT explain HOW the universe got here - they aren't supposed to. They just explain how the universe and life on earth DEVELOPED since the big bang, which is the furthest back that scientists have been able to trace the origin of the universe. Just like the theory of gravity does not explain WHY gravity exists - it just explains HOW it works.

    4. Creationism isn't science - it's just philosophy, because it deals with the supernatural and the untestable. Science deals with what is observable (the natural world only) and testable.
    Was that directed at me?

    No, I was just summing up the anti-evolution comments in this thread, and responding to them. And since I am a multi-account troll, you can just ignore me.

    Genetic bottlenecks of other mammals

    The population of the Eastern African chimpanzee,[35] Bornean orangutan,[36] central Indian macaque[37] and all tigers,[38] and the separation of the nuclear gene pools of eastern and western lowland gorillas,[39] all recovered from very low numbers around 70,000–55,000 years ago.
    I can't really talk to you about the genetic bottlenecking of each individual species, but it seem s that there are at least a few other species that hit this same problem at around the same time that is talked about in the link.
