comment If dinosaurs could have feathers, would they still be reptiles?
I believe the "velociraptors" from Jurassic Park are really Deinonychus, not Velociraptor (the dinosaur on the right). Great point about them having feathers, though!

comment How much heat can a human sustain?
AFAIK the main difference in steam's behavior comes from "latent heat", in which the energy absorbed by the liquid as it changes into gas is released when it changes back into a liquid. But that'll only happen above 100 deg C -> scienceline.ucsb.edu/getkey.php?key=1322

comment How can we create a living dinosaur using DNA technology?
Woolly mammoths were around a lot more recently than that. According to Wikipedia, they diverged from the steppe mammoth around 400,000 years ago and didn't start going extinct until around 40,000 years ago. Isolated populations of woolly mammoths are believed to have existed 4,000-7,000 years ago.

comment More general usage of the term 'congener'
Can you give us an example sentence where you'd like to use this term? I'm finding it hard to understand why you wouldn't just use the family or order name itself (i.e., "Tigers, like other big cats, ..." instead of "tigers, like their confamiliars, ...")

comment Why is it called “Ebola virus disease”, not just “Ebola” or “Ebola disease”?
I notice that a lot of the examples you provide are geographical names. Maybe the convention is to use the name of the disease if there is one (encephalitis, chikungunya) and to use "[geographical place] virus disease" where it's a geographical term to avoid confusing it with the place name (St. Louis, Ross River, Ebola River, the town of Marburg, and so on).

comment From a computer science perspective, how is DNA compared for various purposes?
DNA sequences are usually compared using BLAST (en.wikipedia.org/wiki/BLAST), which breaks sequences into short words which can be searched efficiently. However, that does require having entire sequences around somewhere, which might be a privacy violation.

comment Has a new functional structure ever been observed arising spontaneously?
@r2d2 I've updated my answer to reflect your point. Don't forget that for most (all?) animals, every individual starts as a single cell, so everything is "just the phenotypic expression of a bunch of stupid base pairs", plus whatever else was contained in that cell.
