Compare different species and the time they diverged. Hyenas are cats not dogs. Genetics are fun.

4 kingdoms...

Some biologists have apparently started to use genomics to redefine the kingdom systems into things which actually are related and not just dump the groups off into a big pile if it doesn't quite make sense. The result is four kingdoms...

Plants
Opisthokonts
Excavates
SAR

Where do we fit in you might ask... we don't. There are eukaryotic, bacteria, and monkeys. We're monkeys.

Okay, we're actually Opisthokonts related to the amoebas and fungi all animals are subgrouped in here. So you're a monkey and an opisthokont.
