Imagine that we take a population of horses, split them in half and place them in completely different environments. The two species will evolve separate from each other and because the environment is ...
This is at least partly an historical question, and I am not even remotely a biologist of any sort, so apologies beforehand if it's a little obscure. I often wonder how many distinctions were made in ...
Forgive me if my question does not belong here or if I'm using incorrect terms, but I'm not educated in biology at all. I'm investigating the workings of the biological classification system. I was ...
What is the difference between breed, variant, sub-species and species? Are there any similarities between sub-species and sub-population of a region?
This came up in an argument with some friends. I know that birds are direct descendants of dinosaurs, shown pretty clearly through the fossil record. However, is it proper to say that birds are ...
