Does anyone know of any online resource that has the most accepted tree of life printed, especially for mammals? I would like to be able to view the tree of especially the carnivora (sp) (cats, dogs, bears, etc) and see how and tentatively when they branch.

Thanks,
Pete

Hey Pete

There's a great site Palaeos: Life Through Deep Time that has a pretty complete tree of life. (Thanks to Chiro for pointing me at this site originally.)

I posted this message a while ago in another thread, but I'm going to repost it here as I think it is applicable. You are probably most interested in starting at Mammalia or perhaps Farae.

Be aware, the site is a bit confusing and takes a while of playing to understand how it is put together. There is a lot of information there though and I've learned a lot from it.

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.

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 )

Pete - there's a detailed mammal tree here:
The delayed rise of present-day mammals | Nature

if the site won't let you see it, I'll see if I can post it or something.

"Beats me."

Upon looking at the mammalia chart that you linked, it suddenly struck me that "hominoidea" can be broken up into "homi no idea."

It's a wonder that no creo has jumped on this as proof that "evilutionists" don't know what they are talking about.

Branch lengths are proportional to time, with the K/T boundary indicated by a black, dashed circle. The scale indicates Myr.

This visually should give MartinV pause regarding "no new mammalian orders" issues, because you don't see much change in the rate of branching before and after the KT boundary.

I had a website once that was interactive, you could click on a branch and it would "zoom in" and expand the branch. Thus you could start with the original basic level (say Wikipedia's) and click on mammal and get your tree, select hominids and zoom in on humans. Way cool, but I've lost the link.

Enjoy.

I think that may be one that was in Science about 2003. I'll look this evening at home.

The Tree of Life Web Project

The Tree of Life Web Project allows you to "zoom" in and follow a path up the branches.

If you are particulaly interested in mammals, you can get species-level "supertrees" of the marsupials, the bats, the carnivores, the primates, and the ruminants (or more broadly, the Cetartiodactyla).

By dropping these into place on the tree that Coragyps linked to, you will get a species-level supertree covering a good swathe of the mammals.

A supertree is basically a consensus tree of all previously published phylogenies. So they represent our current combined knowledge of phylogeny but if our current knowledge is flawed or biased then the supertrees will also be flawed and biased. But if you want a really big detailed tree they're the way to go.

Hope this helps,

Mick

PS. In the links above, I have linked to pdfs for the bat and carnivore trees, and to publisher sites for the remainder. If you have no other way of obtaining them I can send you pdfs by email if you like.

not yet

What I saw was done with java script I believe, the round tree of all life would actually zoom in on the branch selected.

Re: The Tree of Life Web Project

I selected the frog and was taken to

Terrestrial Vertebrates

Nice rendering of "The Devonian terrestrial choanates Acanthostega (bottom) and Ichthyostega (on the shore)", which came after Tiktaalik roseae, but still not what I'd seen before (maybe I dreamed it).

There is a java program called TaxonTree, I think that is the one you mean: Biodiversity Informatics Visualization

I believe there is a downloadable version, but the online version is integrated into Animal Diversity Web (ADW: Home) which I prefer to TolWeb because of all the nice pictures! There is supposedly a link on each page to get to the tree viewer, though I am unable to find it. Downloading the standalone application worked fine, though.
