If we are evolved from apes, why don't all ape evolve and become human.
Or
Why the today's ape stop evolving to become a human?

1$\begingroup$ Because their environmental niches suit being apes. Evolution does not have a goal. $\endgroup$– jamesqfDec 12, 2020 at 3:12

$\begingroup$ @jamesqf Why don't all apes evolve then? $\endgroup$– maryaDec 12, 2020 at 3:16

3$\begingroup$ Why do you think apes don't evolve? Like any and all other creatures, they continuously evolve to become better suited to their environment, which is why there are about 20 species of living apes, each suited to their particular environments. And I downvoted your question because I think it is pure creationist claptrap. If it's not, the answer is pretty obvious: why do we have different species of cats, bears, equines, or any other group? $\endgroup$– jamesqfDec 12, 2020 at 4:15

I am not going to bother putting any references for this answer as all the information is a google search away.
Humans did not evolve from apes. Extant humans and apes developed from a common ancestor. One lineage from this common ancestor evolved and became apes. Another lineage went on to become humans.

Unless one can describe a "common ancestor", this phylogenetic knee jerk response begs the question. Humans evolved from animals not distinguishable taxonomically from apes. Phylogeneticists invoke the common ancestor explanation because their analysis is actually a form of cluster analysis, where groups of traits split dichotomously into smaller groups of traits. This is not a model of evolution.
