Where is it given as a fact?

comment Function and Mechanism of Height Genes
Can you link to the sources that postulate "on/off" genes or to what some of those genes might be? That would help potential answerers follow the paper trail to the function of those genes.

comment Why do we spend so much time on creating taxonomies?
Your question is too discussion oriented for the stackexchange format. The answer invariably will be "it depends whom you ask." I suggest looking at the broader impacts section of the grant that supported your work, which should answer the question "why does this matter?".

comment Why do crabs spit?
Can you add some references to your answer, specifically the "airing out" process and those who hypothesize that stress is the cause?

It looks like the phylo constructor changed since the link posted above: stat.ethz.ch/pipermail/r-sig-phylo/2014-May/003467.html

comment Construct Phylogeny form Edgelist
It seems like standard edge list format is two columns (e.g., for igraph: shizukalab.com/toolkits/sna/sna_data). Can you output your list in that format?

comment Why do sneezes come out the mouth?
To say that "all of the rapidly-expelled air" comes out of hte mouth is not accurate. Maybe the amount that comes out of the nose is sufficient.

comment Is it “easier” for researchers to detect evolutionary ancestry than distance in the evolutionary tree?
In short, extant species are not ancestors of one another because, even if they are sister taxa, each has its own separate evolutionary history since they diverged. So, no to question 1.

comment Human Bones classification and anatomy quiz
@AliceD I disagree. Here's a question with a valid attempt at answer, seeking clarification. Seems like a reasonable homework question. Maybe not the more interesting, but valid and worthy of answering.

comment Human Bones classification and anatomy quiz
As you not in your question, I think there are some difficulties in translation. I suspect that "plane" should be translated as "flat", that "mixed" is likely "irregular", and "odd" and "even" are "paired" and "unpaired". Does that sound right?

Limbs with bone in them and fins with fin rays (lepidotrichia) in them are different. Which one are you interested in?

Do you have a citation or source that asserts that elastin and collagen production cease?

comment Efficient algorithm to calculate various population divergence statistics
Have you looked at BioPython? Specifically the Genepop module (biopython.org/wiki/PopGen_Genepop) looks useful. If you've already got some Python experience, it might be the fastest way to get started.

comment If dinosaurs could have feathers, would they still be reptiles?
You say "Some dinosaurs actually had feathers". I'd go further and say that every taxon that we know of that has or had feathers is a dinosaur.
