The above is garbage since fossils do not show a placenta and there is no DNA to make such a comparison. What we do have are live specimens with and without a placenta. The problem is that since both examples are alive NOW it is only an evolutionist assumption that leads to the conclusion that those without a placenta came before those with one. In addition because there is no way at all to tell what the DNA of any species was a million years ago or a hundred million years ago, there is absolutely no way to calibrate this so called 'clock'. There are more problems with the molecular clock such as that different DNA tests give different cladistic diagrams and the fact that evolution assumes that all species are continually being changed by mutations which means that according to evolutionist assumptions a human and lizard have undergone as many years of mutations as each other since the supposed descent from fish. Thus any study that claims to use a molecular clock is dishonest and absolute nonsense.

The study didn't rely on fossils, try again... I repeat, the first requisite to being able to attempt to rebut something is to first *understand* it properly.
and there is no DNA to make such a comparison.
The researchers *did* use DNA to make the comparison. Learn to read.
What we do have are live specimens with and without a placenta.
And some with *partially developed* placentas. Is there some reason you "forgot" to consider the significance of that?
The problem is that since both examples are alive NOW it is only an evolutionist assumption that leads to the conclusion that those without a placenta came before those with one.
You totally misunderstand the point of the study, but oh well.
In addition because there is no way at all to tell what the DNA of any species was a million years ago or a hundred million years ago, there is absolutely no way to calibrate this so called 'clock'.
There are many ways, actually. Try reading the literature.
There are more problems with the molecular clock such as that different DNA tests give different cladistic diagrams
Actually, the results are remarkably consistent and the causes of the few anomalies are pretty well understood.
and the fact that evolution assumes that all species are continually being changed by mutations
No, actually, it doesn't. Why don't you learn something about evolution before you attempt to debate it?
which means that according to evolutionist assumptions a human and lizard have undergone as many years of mutations as each other since the supposed descent from fish.
But not necessarily as many retained mutations. You seem pretty unclear on the basics...
Thus any study that claims to use a molecular clock is dishonest and absolute nonsense.
Your arguments are flawed, therefore your conclusion is faulty.
