Animals condisered to be of the same species:
a) can interbreed to for fertile offspring
This is the definition of a species. Interbreed means not just reproduce like male and female labradore dogs, it means a labradore and grey hound, these are from different breeds, but their offspring mongrels will still be feritle. A lion and tiger will produce a liger that is infertile.
b) live in the same area
This is not the definition of species, humans are one example of a species that live in different areas. When a species occupies an isolated area and there is no mating outside, evolution will sellect characteristics such that over a very long time a new speices emerges.
c) look alike
This is not the defintion of species. In humans, peacocks, bower birds the male and females do not look similar.
d) all of the above
As c) and d) are excluded it can not be all of the above
About Me

- I come from a Science family: My father Geoffrey Hill was Australia's first computer programmer on CSIRAC the fourth computer in the world. He is credited with invention of Computer music and the development of “Interprogram” a language before Basic. My PhD is in Atomic and Molecular Physics. I have researched the activated oxygen layer above the ozone layer, and 'Assigned' the world's smallest molecule. At the University of Toronto I researched high power UV lasers. I have specialized in automation in fibre optics. This developed into research in Machine Intellect and Robots. I have enjoyed work as an Explainer with Questacon and my time as a part-time soldier. I currently teach High School Science at Epping Boys’ High.
