If it were to happen with humans, you could expect it to happen with other species. Does a lion who taste (say) another lion get similarly hooked on lion flesh? If not, what would be special about human flesh?
Some suggest that animals hunting humans would likely do so because they’re older/injured animals who have a harder time catching their natural prey.
Predators often select the weak within their natural prey, such as the young or the old. So it does happen with other species.
> Does a lion who taste (say) another lion get similarly hooked on lion flesh?
Lions won't select other lions as prey because lions are notoriously dangerous game. Unarmed humans are very easy targets, however. That's the "hook".
If Lions who attack humans always get killed, only the ones that don't survives and reproduces.
If it's about opportunity (makes sense, catching a human does seem easier than an antelope) rather than anything intrinsic to human flesh, then why would killing them so that they don't reproduce matter? "Opportunity" does not get transmitted genetically.
And how would a lion taste another lion? Killing cubs? It happens, but the lioness is putting a strong fight, it is easier to eat humans.
From Wikipedia (article: Lion):
"When one or more new males oust the previous males associated with a pride, the victors often kill any existing young cubs, perhaps because females do not become fertile and receptive until their cubs mature or die. Females often fiercely defend their cubs from a usurping male but are rarely successful unless a group of three or four mothers within a pride join forces against the male."
What you say is true however: lions won't select other adult lions as their prey, for obvious reasons.
