Dr Edwards: What is a species and why is it difficult to define?
A species is the only level in the heirarchy that can be defined. Its not something that humans create and so it has a little reality to it. Genus, Family class and the level below it is not real and depends on taxonomist. Why is it difficult to define? Because species are changing while we are looking at it. It is not static but evolves with time. Something that is a species now may be another species in the future. The other problem is, there are a lot of variation in a species.

And we spent one whole hour JUST to define a species. HAHAHA. This is one of what i study fyi. Interesting yes?
