I am a computational biologist with a background in biology, not computers. My PhD work was on gene prediction and comparative genomics but my current research is in systems biology, specifically protein-protein interaction networks.

comment Largest direct ancestor of humans
@Remi.b the Dimetrodon is not a mammal. I can't find it on NCBI Taxonomy oddly enough, but according to the Wikipedia link you posted: "Dimetrodon is nevertheless more closely related to mammals than it is to any living reptilian group, though it is not a direct ancestor of any mammals."

comment How to generate a set of intercorrelating genes using R language?
Bioinformatics questions are often borderline here. If you're asking about the underlying biology, they're on topic. If the answer you are looking for is code, they probably aren't. You might want to check out biostars.org instead.

comment What does to “evolve” exactly mean?
Ooker, English Language & Usage would be the best fit but you'd just receive the same answer as posted by @Mr.ShinyandNew安宇 above. Almost certainly by Mr Shiny himself. Feel free to post there or flag it and ask for migration. Just be warned: the ELU folks don't believe in the kind of prescriptivist ideas that prompted your question :). They're a firmly descriptivist bunch. You might also want to discuss it in the ELU chat room

comment What does to “evolve” exactly mean?
In any case, as has already been pointed out to you, you cite just one definition and even that one only states that it is "especially from a simple to a more complex form." That does not mean exclusively. Other definitions include the specific meaning used in biology. Also, dictionaries do not define words. Usage defines words and those definitions are then included in dictionaries. Finally, there are many examples of evolution leading from a simple to a more complex organism, just like your definition suggests. I don't see an issue here.

comment What does to “evolve” exactly mean?
@Ooker actually, biologists are quite careful when using the term. It is just horribly abused by the popular press. Things like "more evolved" for example will not be used by people working in the field.

I think this may be off-topic because it is about semantics, not biology.

comment Why can't we defibrillate the heart within 1 minute after ventricular fibrillation by electroshock?
@Majid that's fine, you should always accept whichever answer you prefer. I just found your choice surprising, that's all. I did not mean to pressure you to change anything. It is completely up to you.

This answer would be greatly improved if you could add references supporting your claims.

comment Why can't we defibrillate the heart within 1 minute after ventricular fibrillation by electroshock?
@Thirdkidney I am surprised you accepted the other answer. It makes a lot of claims with absolutely no evidence to back it up. It is, essentially, the opinion of some random internet user. I'm not saying it is wrong (I don't know and cannot judge), just that there is no reason to think it is correct. This answer, on the other hand is supporting its claims with references so if the two answers disagree, I would believe this one. Incidentally, I also happen to know that Medica is a practicing physician, yet another reason to rethink your acceptance.

comment How much energy does a lion contain?
@fileunderwater I quite agree with points 1 and 2. However, the answers clearly push it into the realm of physics in my opinion. I don't see any biology in any of them. Which is not to say they are not fine answers, just not biological ones. I don't see how this can be answered by biology, it is pure physics.

comment How much energy does a lion contain?
@Nit oh, damn. I can't vote to migrate (we have no path to Physics) only close. I think this is a cool question I just don't see anything biological about it. You could ask exactly the same thing replacing lion with stove.

comment How much energy does a lion contain?
This question appears to be off-topic because it is about physics, not biology. It just happens to use a living organism as an example.

comment How much energy does a lion contain?
I think this would be a better fit for Physics. I don't see how this is a question about biology. Fun question mind you, just off topic.

comment Can white eggs be considered as non-vegetarian?
@ChrisStronks I never made any such claim. The OP asked for a biological answer, not a cultural one. Eggs are animal cells and, therefore, animals. Whether you should eat them or not is up to your own sense of morality and I wouldn't presume to offer an opinion. That they are an animal cell is not debatable however, that is a simple fact.l

comment Can white eggs be considered as non-vegetarian?
@Anixx actually, none of the egg's matter consists of cells. The egg itself is a single, huge cell.
