Valerie, the scientific fact of man descending from apes was never debunked by reputable scientific institutions. You are providing a quote from the Institute for Creation Research. Its title indicates its purpose is to prove creation theories.
Here's the Wikipedia explanation for the Institute for Creation Research:
The Institute for Creation Research (ICR) is a Creationist apologetics institute in Dallas, Texas that specializes in media promotion of pseudoscientific creation science and interpretation of the Genesis creation narrative as a historical event. The ICR adopts the Bible as an inerrant and literal documentary of scientific and historical fact as well as religious and moral truths, and espouses a Young Earth creationist worldview. It rejects evolutionary biology, which it views as a corrupting moral and social influence and threat to religious belief. The ICR was formed by Henry M. Morris in 1972 following an organizational split with the Creation Science Research Center (CSRC).
Its work in the field of creation science has been rejected by mainstream science
, but has been significant in shaping creationist thought in the United States by introducing creation science through fundamentalist churches and religious schools, and by engaging in public debates against supporters of evolution. The ICR also offers non-certified graduate level programs in Biblical Apologetics, including a minor in Creation Research. In 1992, the ICR started the Museum of Creation and Earth History and hosted adventure tours, but it was sold to Life and Light Foundation in 2008.
(There is probably a reason why Clixsense does not allow debate in the political or religious fields.) Here's a good article on proof of evolution theory: Are humans really descended from apes? | HowStuffWorks
