Great site Chiro, if a little confusing.
Being an extreme amateur at the whole 'tree of life' thing I finally took some time to run through the entire history of man from an evolutionary point of view and put some times against them. Hopefully it's of use to others as well.
So starting at
Chordata here is the full chain that I was able to trace to modern man. I'm not sure what level (phylum/order/family) these all belong to, so if someone more educated wants to fill in that info I would appriciated it for my own sake.
Assuming that each of these are equally 'distant' from each other (a vast and unfounded assumption) and also assuming that the 7500 level number that I've seen bandied around, that gives about 200 'levels' per line item below.
Chordata (early cambrian : 540mya )
Craniata (early cambrian : 540mya )
Vertebrata (lower cambrian : 540mya )
Gnathostomata (ordovician / early silurian : 438mya )
Teleostomi (late ordovician / early silurian : 438mya )
Osteichthyes (late silurian : 410mya )
Sarcopterygii (early devonian : 400mya )
Rhipidistia (early devonian : 400mya )
Osteolepiformes (early / mid devonian : 390mya )
Elpistostegalia (mid devonian : 380mya )
Tetrapoda (late devonian : 360mya )
Reptilomorpha (early carboniferous : 350mya )
Batrachosauria (carboniferous : 320mya )
Cotylosauria (carboniferous : 320mya )
Amniota (late carboniferous : 280mya )
Synapsida (upC : 280mya )
Eupelycosauria (early permian / late permian : 280mya )
Sphenacodontia (upC : 280mya )
Therapsida (early permian : 280mya )
Theriodontia (mid permian : 260mya )
Cynodontia (late permian : 250mya )
Eucynodontia (early triassic : 240mya )
Probainognathia (late triassic : 210mya )
Mammaliformes (late triassic : 210mya )
Symmetrodonta (upT-upK : 210mya )
Mammalia (mid jurassic : 170mya )
Cladotheria (mid jurassic : 170mya )
Theria (mK : 170mya )
Eutheria (mid cretaceous : 100mya )
Epitheria (late cretaceous : 65mya )
Archonta (late cretaceous : 65mya )
Primatomorpha (late cretaceous : 65mya )
Primates (late cretaceous / early paleocene : 60mya )
Haplorhini (early eocene : 50mya )
Anthropoidea (mid eocene : 45mya )
Hominoidea (late oligocene / early miocene : 20mya )
Hope it's helpful to someone other then me.
