Anybody knows of a simple definition and example of Homology. I read somewhere it's similarity in DNA among individual species or different species. I'm not quite clear on how it works with different species. Does it just mean humans-humans are similar and another species would be bear-bear? Oh, yeah I'll be posting random words because I'm a bit confused about them, thanks.
metazoa - all animal phyla more advanced and complex than sponges. Meaning multicellular animals e.g. humans?
