Sharks (a type of cartilaginous fish) and trout (a type of bony fish) both obtain oxygen from the water through their gills. Interestingly, an accurate phylogenetic tree including only sharks, trout, and humans (a type of mammal) would place humans as the sister group to trout! This shows that gills are a:
a. synapomorphy that distinguishes trout and humans from sharks
b. plesiomorphy shared by sharks and trout, but secondarily lost in humans
c. synapomorphy used to distinguish fishes from mammals
d. plesiomorphy revealing why humans are distantly related to trout
