Asking why there is no human apes alive today is like asking why your great grampa from the 1800's is not alive..
They only get to live one life time just like any other living thing.. its there off springs that may change,. and after many generations things dont look the same..
Its simple,. most of us look like our parents , our kids look more like us and they look less like our parents,..and there kids look less like us..rinse an repeat.
now repeat this for 200000 years and think of the question once more. yep,. your ape father died 1000's of years ago.
