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).

comment Presence of MHC on red blood cells
@Biogirl - They can be if they have the wrong blood-type or Rh factor.

comment Number of genes required to sustain life
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.

comment What is a “pure odorant”?
@JohnC - More or less. Peanut Butter has a unique scent and is readily available. Using purified Limonene would work, as I'm sure there's a nerve profile for Limonene - but the purified product isn't readily available. The benefit of Peanut Butter is specificity. It's a known scent (to people in countries that like peanut butter), and a unique scent that's instantly identifiable. You could confuse oranges with limes or lemons by scent, but a healthy person will always recognize peanut butter as peanut butter. It tests sense of smell and cognitive function simultaneously.

comment Why are urban birds still scared of humans?
What's your evidence that an individual animal who has never encountered humans before is "scared" of humans more than other species?

comment Abnormal Prolactin Level
It could be, but this website is NOT for medical advice. If this is your personal condition, please seek a qualified medical professional. If this is a hypothetical condition, please clarify exactly how Prolactin levels are abnormal (hyper- or hypo-) and what you mean by 'nodule near the pituitary'.

comment What happens if an IV drip with a saline solution slips out of the vein, but keeps dripping into the body?
Well, I simply do not know how dangerous it is. My intuition says it's not particularly dangerous since the extra fluid is, eventually, absorbed. However, I'm not a medical professional and don't know the circumstances that dictates when it becomes dangerous. Thus, the big warning at the beginning. Better safe than sorry. :-)
