comment human digestion: (spicy) food eaten at night is excreted next morning
Have you done the experiment of eating spicy food first thing in the morning to test the hypothesis of more rapid digestion of spicy foods?

comment If dinosaurs could have feathers, would they still be reptiles?
@WYSIWYG No, birds are within the clade Reptilia, and thus are reptiles.

comment Why is the autonomic nervous system divided into parts?
Can you narrow down the question? One could write books on the evolution of the ANS. By "development", do you mean evolution or embryology?

From where do you understand this? Could you provide a source?

It would actually be better if you summarized the main points of the articles.

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.

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.

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."
