Alex_Trebek 0 Posted September 3, 2009 Author Share Posted September 3, 2009 I'm going to say: What is a Reptile Alex?CORRECT!Balloon Guy: 1000Human evolution for 1000:According to genetic studies, humans and chimpanzees diverged from their common ancestor about this many years ago. (of the choices 6,000 years ago, 60,000 years ago, 600,000 years ago, 6,000,000 years ago, 60,000,000 years ago, 600,000,000 years ago). Link to post Share on other sites

Humans and chimpanzees diverged from a common ancestor somewhere between 5 and 8 million years ago. However, you were only off by about 54 million years. Balloon Guy: 0Next category please!

Balloon Guy: 0Next category please!that's what I first wrote...six million, I just starting thinking how ridiculously short of a time span for random chance to mutate the changes that represent ~100 millions bits of DNA code that differ between chimps and man... ( yes, that's what 3-4% difference in DNA between the two species would represent...~100 million bits of information )Okay fine.Let's do Genetics until it's finished Alex.

brvheart 1,750 Posted September 3, 2009 Share Posted September 3, 2009 I guess you're right.100 millions of bits of different DNS sequences...6 million years, thats only 21.36 benefitial mutations per day.I guess that's well within the parameters of evolution...It looks like we won the powerball several times!

vbnautilus 48 Posted September 4, 2009 Share Posted September 4, 2009 So we only won Powerball like a couple times a year?There is about one mutation per sex cell in humans due to copying errors. You guys are saying six million years isn't long enough to accumulate some good ones? Is that what you are saying? Then, how long would be? Link to post Share on other sites
crowTrobot 2 Posted September 4, 2009 Share Posted September 4, 2009 So we only won Powerball like a couple times a year?the odds of beneficial adaptations occuring and proliferating (at least in small reproductively isolated populations) are pretty close to 100%, so there's no analogy there Link to post Share on other sites

The nucleotides are made up of three major parts.1) Deoxy ribose(pentose sugar)2) phosphate group3)bases ( PurinesOkay..you got me there Mr. Trekekekekl Link to post Share on other sites
