I have put important words in bold. These words are important in biology and I will refer to them throughout the post. It isn't overly important for you to know the exact meaning, so long as you get the gist of what I'm talking about you will be fine following this post.
Writing Links are in italics and these discuss how the science could be used in writing.
A bit of background science
In biology it is important to classify different organisms. This classification is done so that organisms with similar biological characteristics are grouped together which makes researching them and discussing them a whole lot easier.
The system works down to identify species. Before any further discussion can be made we should look at the definition of a species:
A species comprises a a group of individuals that can usually breed to produce fertile offspring.
