In addition they gathered samples from present day cats for comparison. For each of those samples they looked at mitochondrial DNA, genetic content present in each individual mobile that is definitely handed on from mom to child, making it a practical tracer of evolution.
“Cats have performed considering the fact that prior to they ended up domesticated what we wanted them to carry out,” states Leslie Lyons, a feline geneticist within the College of Missouri.

.. is really benefiting from its romance from individuals,” she suggests. But that sort of relationship isn’t a thing that is simple to pinpoint employing DNA by yourself.
