comment Sexing fish from a tissue sample
@Tone You last comment is the kind of detail to add to the question.

comment Why do mammals produce more carbon dioxide than insects?
From where do you understand this? Could you provide a source?

comment Selection Pressure on Orca Whale Coloration
It would actually be better if you summarized the main points of the articles.

comment What are some useful (starter) metrics to use on phylogenetic trees?
Call R from Python: rpy.sourceforge.net/rpy2/doc-dev/html/introduction.html

comment Are fishes evolving?
I would disagree with the phrasing "to avoid" and replace it with "in response to". The old adage about evolution not assuming a purpose applies here.

comment Why doesn't EMG data for triceps show a clear relationship?
Is gravity doing most of the work? There would be no reason for the triceps to be active. Repeat the movement yourself and feel the muscles. You'll find your biceps contracting to control extension of the elbow.

comment Why doesn't EMG data for triceps show a clear relationship?
Can you describe the experiment? What actions are happening at the elbow? Since the triceps is an elbow extensor, you don't expect it to be active during flexion much, e.g. during curls.

Can you try to narrow down your specific question? We have a page on questions: biology.stackexchange.com/help/dont-ask

comment Why does supercoiled DNA run faster?
Can you write a title that more closely relates to the question? Reading the title, I thought the question was about snakes.

comment How much force can connective tissue withstand?
Do you have a specific connective tissue in mind? I'm guessing you are thinking of cartilage and ligament (blood is technically a connective tissue). Also in what orientation are the loads you are thinking of? Compression is very different from tension.

comment Does the human abdominal cavity use pressure to maintain posture?
This addresses the IAP issue, but not the actual question about posture.

comment How quantitative is the theory of evolution right now?
By "we", do you mean humans or animals in general?

comment Why do only two sexes exist for animals?
I don't think you can say whether or not additional sexes would be beneficial or not, without some theoretical or empirical basis. Just because a trait hasn't evolved, doesn't mean that it wouldn't be beneficial if it did (e.g., wheels).

comment Why do only two sexes exist for animals?
Is there evidence for this statement? "More than two would confer no further genetic benefit for either repair or diversity, and would likely introduce complexity and inefficiency."

Chromosome of what?

comment What is the point of a runny nose during a cold?
Does it need to be evolved? Can it not just be a side effect of some inflammatory process?

This doesn't really answer the question.

comment Why can't we call dog breeds different species?
I don't think this really answers the original question.
