hooberus - the evidence for the common ancestry of all living things that is found in our genome is off-the-scale compelling.
It requires an a priori religious motive to deny it. How about explaining your objections in your own words instead of the cut-and-paste appeals to authority?
Here is a very simple snippet of evidence that I personally find very convincing....
Occasionally a virus will infect an animal and get its DNA implanted in its host genome, HIV is an example of such an infection. Most infections are of soma (body) cells and end with the death of the hapless victim. Very occasionally a virus will infect a germ (sex) cell of its host and will then become part of the genome of all of its victims descendants.
These kind of infections, known as "endogenous retroviruses", are very rare and very random. Remember your DNA consists of 3 billion base pairs and is split into 24 pairs of chromosomes. If the same remnant of a virus was found in exactly the same place in the genome of two different people it would be irrefutable evidence that they both inherited it from a common ancestor.
If many such examples were found that exactly matched in two people we know for an absolute certainty that they have shared the same family tree.
Now that the whole human genome has been deciphered many of these examples have been found, every one in exactly the same place proving the common ancestry of every human on earth. However scientists next looked at the genome of the primates and found the very same remnants of ancient virus DNA in exactly the same places.
Not only that but they found a "family tree" of endogenous retroviruses that confirmed exactly the relationships we previously believed to be the case. In other words those species we knew for other reasons to be our closest relatives share more endogenous retroviruses than those more distantly related. We can therefore show exactly when each of these viruses infected our common ancestors.
This is the same kind of evidence with the same degree of certainty that scientist use every day to establish paternity or to convict those accused of serious crimes.
