comment How is it proved, that antediluvian people didn't live for hundreds of years?
@SuzanCioc - The problem is that without some basic assumptions the current scientific understanding can't actually answer your question. What is possible is significantly different from what is supported. If you have questions regarding a specific data type - like morphology or genetic data - then you'd get a more specialized and more detailed response. Simply saying "We weren't there so how can we know for sure?" is sort of like trying to prove I'm human and not a computer program despite only communicating online. ;-) In order for things to function, basic things must be assumed 'true'.

comment Human evolution: Where *exactly* did the first human come from, whose parents were not?
@Jim - I didn't call them our ancestors. I called them our 'closest evolutionary cousins' as the species we evolved from are now extinct (although they did use tools as well - but we've known that for some time).

Since RNA is the presumed precursor to DNA and might have sustained life before DNA evolved, do RNA counterparts count?

comment What is a “pure odorant”?
@JohnC - There may not have been a very good reason. They wanted something with a unique smell that was cheap, and Peanut Butter was probably a convenient option. More important than the smell is the caveat that the lack of smelling abilities found in the study can be attributed to more than just Alzheimer's. It's a quick and dirty early signal, but it also has a pretty high false-positive rate.
