Now researchers have utilized genetics to generate by far the most intensive map ever made of cats’ path to worldwide domination, released this 7 days from the journal mother nature
Evidence reveals that these ancestral creatures bred with area animals, leaving behind distinct DNA which is found in our modern-day Animals.
This may be an excellent start, states Greger Larson, a paleogenomicist at Oxford, and it sets the phase for applying historic chromosomal DNA to much more refine The story of historical cats.
