Re:

To a large extent that is true of most vertebrate species. What we often think of as "genetically programmed instincts" are in fact the product of conditioning by experience. It's the age-old nature vs. nurture debate. Partly true, but some particular examples of physical sexual dimorphis...

Re: are the horse and chicken related?

Like all members of the animal kingdom, they must share a distant common ancestor (they both have what is known as eukaryotic cell structure). They're related in the same sense that all modern animals, plants and fungi are related - very distantly. At some stage in primeval natural history, a single...

Re: Evolution

And my last question is, Ricin is highly poisonous for most animals, including insects. This substance protects plants from animals that would eat the seeds. From the perspective of evolution, how can we explain that plants evolve characteristics/traits that are helpful for the them? Plants which l...

Re: Evolution of the distinction of gender

Sexual dimorphism in some species also seems to have important results in terms of encouraging pro-survival activities and behaviours. For example, in insect populations like bees and ants, the phenomenon of gender allows members of the group to assume radically different roles - a kind of "div...

Toxicity/harmfulness of food stabilisers in large quantities

Hi all, Firstly, I do hope I've posted in the right forum - being something of a biology rookie I wasn't quite sure under which category this question might fall, but since it has to do with human biology I'm hoping I've posted correctly. Sincere apologies if I haven't! Anyway, I'm interested to kno...
