Jordan peterson, a culturally popular psychologist, has made the following biological claim:
Human beings and their closest biological relatives, chimpanzees, are innately afraid of and attracted to reptiles.

The claim is plausible and believable. I know many people fearful enough of snakes and reptiles that they won't even touch one. I also know nearly every little boy would put one in his pocket. What gives concern before I'd take this without challenge is that Peterson has a long line of theory that nearly hinges entirely on this point.
I'm sure he's not the first to suggest this, so I suspect there's proper studies on human/chimp fear of reptiles. What does the evidence say?
He makes many other evolutionary and behavior claims derived from this base claim. They are equally questionable, but testing all in a single question is probably too much.
