Barriers to interbreeding

Baffling Genetic Barrier Prevents Similar Animals from Interbreeding from Scientific American
"In new research published in June in the journal Science, Wolf’s team has found that a surprisingly small chunk of DNA may hold the answer. A comparison of the carrion and hooded-crow genomes showed that the sequences are almost identical. Differences in just 82 DNA letters, out of a total of about 1.2 billion, appear to separate the two groups."
