Wolf Evolution and "Settled Science"
Are the red and eastern wolves separate species, or hybrids with coyotes? And what has that got to do with climate change? Actually a lot, in illustrating what scientific inquiry is and what it isn�t.
COMPARING CANID GENOMES
A report in this week�s Science Advances questions conclusions of a 2016 comparison of genome sequences from 28 canids. The distinction between �species� and �hybrid� is of practical importance, because the Endangered Species Act circa 1973 doesn�t recognize hybrids. But DNA information can refine species designations � or muddy the waters.
