So why then, if man and chimpanzee and orangutan and gorilla all evolved
from one common ancester, why can we not trace back their family tree?
I don't know what we have from the fossil record, but you have to
understand that it is very incomplete because we only find one in of many
thousands or even many millions of remains. Animals with hard shells or
bones can be found more easily. We also seem to find bones in deserts and
we don't look for them 1,000 feet underneath of a jungle. So we are
missing many samples that might exist and many more animal remains are
simply completely lost forever.
A better, more modern way of determining phylogenetic trees is to look at
DNA similarities. We are most like the chimp.
