Which of these provides evidence from developmental biology of a shared evolutionary history? a. the skeletal structures of a leg of a horse and a flipper of a whale are very similar. b. both snakes and dogs have pelvic bones even though they are vestigial structures in the snake. c. both lobsters and frogs go through metamorphosis as a process in their life cycle. d. the dna sequences of the cytochrome c genes in chimpanzees and spider monkeys are over 90% identical.

D. The DNA sequences for the cytochrome c genes in chimpanzees and spider monkeys are over 90%  identical.

Cytochrome c gene encodes for a protein that is very common among primates. This gene does not have undergone much changes during the process of evolution. Cytochrome c is a respiratory pigment found in the mitochondria of eukaryotes.

the most common type of reef is the fringing reef. this type of reef grows seaward directly from the shore. they form borders along the shoreline and surrounding islands.
