Re: New Limbed Cretaceous Snake



<<Blair Hedges, an evolutionary biologist at Pennsylvania State
University, US, says: "In one fell swoop, this new fossil kind of
casts doubt on the aquatic hypothesis."

His DNA sequencing studies suggest a terrestrial origin for snakes.
And he says that, looking at evolutionary history, it is difficult
to find examples of limb loss in an aquatic environment.>>

Can somebody please explain how DNA sequencing was done in relation to this fossil?

Not at all of course. Hedges did his studies long before *Najash* was discovered, on extant species -- and he never says otherwise.
