Description : What evolutionary advantage did the compulsion toward religion confer on humans?

Last Answer : Have there really been 110 billion humans? I think I’ll need a source for that. Every biologist I’ve ever heard mention it says that more people are alive today than have ever been alive in the past. So, we’re talking 16 billions, max.

What would be the evolutionary advantage given to mockingbirds by mimicking other birds?

Description : What would be the evolutionary advantage given to mockingbirds by mimicking other birds?

Last Answer : Pure speculation here, but since one of the functions of bird song is to lay claim to a territory, maybe it’s the bird equivalent of posting “No Trespassing” signs in several languages. Could be that it deters competition not only from other mockers, but from other rivals for food resources.

What is the evolutionary advantage of the occurrence of sperm cells and larval stage in the life cycle of sponges?

Description : What is the evolutionary advantage of the occurrence of sperm cells and larval stage in the life cycle of sponges?

Last Answer : The sexual reproduction in sponges, in addition to contributing to genetic variability, also facilitates the colonization of farther environments by these beings, since sperm cells and larvae are mobile and can swim in the exterior to compensate the immobility of the adult individual.
