Protein Phylogeny
The tree shown below were produced by program Phylogeny.fr [1] using protein FASTA sequences of KRAS protein homologues obtained from Homologene [2]. Each tree was generated using different construction parameters. Phylogeny.fr
allows one to determine the phylogenetic tree using the FASTA format of genes and proteins.
TreeFam Phylogenetic Tree
The above tree was obtained from TreeFam[2].
Analysis
The phylogenetic tree obtained using the program Phylogeny.fr[1] and the one from TreeFam is highly similar, indicating the likelihood of the results being accurate. Expectedly, Chimpanzees and humans are the closest in the phylogenetic tree as chimps share up to 98% of human DNA. C.elegens being further from all the mammals is also an expected result, since, as an invertebrate, it's evolution probably diverged long ago from mammals.
