(115,734 posts)Sometimes there are dead ends and a species becomes extinct; this can be the result of any number of circumstances.
Humans are not the only species that kills its own kind. Other animals kill members of their own species as a result of competition for territory, food or mates. Male lions that take over a pride often kill existing cubs so they can mate and produce their own cubs, keeping their own genetic line going (like medieval human kings). Adorable little meerkat females kill and eat the young of subordinate females. Humans are actually less murderous than many other species. The only difference seems to be motivation; humans are more likely to be proactively violent than most species other than chimpanzees.
