There is always an exemption to the rule!

It can happen to transgenders, can't it? How ever biological males will really be incapable of conceiving no matter what happens.

Can someone tell me if the music is Tchaikovsky? If not who and what concerto...

The title is kind of misleading. This phenomenon happens with a lot of female pregnancies in the animal kingdom as well. For example birds will eat the eggs they lay if there is a lack of food.

@regemo Hi there!! I am writing to you because you seem knowledgeable about this study. Forgive me for bothering you but I've been trying to search for a study that tells WHY nature sought it so that in majority of species, there is a sexuality separation. What was it that led to the requirement of males and females rather than a single sex? Would you know where i should look for it? (on the internet only please). Thank you so much for ANY help!!

[regemo]

@vegeteriancannibal I remember an argument that gender might have arisen from the necessity for some species to carry the undeveloped young until they are born, as opposed to just laying eggs. Carrying the young around meant the animal was less proficient at hunting for food and less able to defend itself from predators. Having a mate that does not become pregnant increased their survival and were better able to pass on their genes. Leading to more gender specific members of that species.

Respond to this video... But the most convincing theory for the origin of gender is that in fungi it might have developed so that fungi didn't fertilize their own self. Having a gender type allowed fungi to fertilize with other gender typed fungi and mix genes. Type "lotus artificial life origin of gender" in google for a website with a lot more theories.

Of course in animals with more complex brains gender does not necessarily determine sexuality. They are not equivalent.

@regemo Thank you so much, English is not my first language so I was struggling for the right phrase to Google. ''Origin of gender'', so obvious. I feel stupid right now, hehe!!

Anybody know if this sinister Mom role (snacking on one's young in utero) is also seen in females in comparable species?

[lootje84]

I want to know the song! Have been searching for such a long time! This reminds me of Belle and the Beast from Disney but I know It's different

[SHAVENAPE]

It's Saint Saens, from Carnival of the Animals, entitled Aquarium, appropriately enough.
