Phylogenetic relationship between zebra finch (zf_), chicken (gg_), and human (hs_) caspases. Numbers indicate the robustness of each node assessed by bootstrap. Two caspase-3-like genes from opossum (md_) are included. Casp, caspase; malt, paracaspase; cflar, casper; iceyh, homolog ICEY. The phylogenetic tree was rooted with the paracaspase family.
