So I have recently interacted with a handful of pets, petting them along their torsos and not just their heads and back. They have most of the same organs protected in a ribcage that humans have. And they seem to have similar organs unprotected (kidneys, namely, we're all wary of a kidney punch in a barfight).
I'm wondering at what point in the divisions that occurred [theoretically, 40 days 40 nights, all that] that some creatures branched into each of the following with the same general kinds of arrangement of organs and quite similar protections of subsets of those organs:
a) humans
b) dogs
c) cats
d) a whole big list of animals (who I might just be proven wrong wrt the premise of my question)
I know there are at least a few of you that delved deeply into biology or other related topics that might be able to address this in some way. I am curious.
I thank any useful responses in advance and might thank useless responses as they arrive!
