I've been watching nature shows on Netflix (Wildest series) and different animals of the same "family" are actually different species.
e.g. Asian elephants vs African elephants. Asian elephants are much smaller than their African counterparts.
Also with monkeys, different locations have their own species. Take langurs for example (see link below)
Just in the Indian subcontinent, there are many species of the same "gray langur".
In saying all that, how many species are there of modern day humans? It can't be just 1 homo sapiens it's quite obvious there are differences based on location. (Africans have darker skin. East asians have distinctly-shaped eyes and etc). Monkeys have lots of species even of the same "family" (see example above) and we're also primates.
