That said creatures that are similar morphologically will also be similar in terms of cytochrome c. The nested patterns of both will tend be in agreement. This could not be a result of chance, but that does not mean that evidence against chance is evidence for evolution.
There are two books that I would recommend on life’s overall pattern morphologically and genetic.
“The Biotic Message” by Walter ReMine
”Evolution a Theory in Crisis” by Michael Denton (especially chapters 5, 6, and 12).
Dont be dissuaded by negative evolutionist “reviews”. There is a lot of decent info in these 2.
