Their length is between 18 and 20 inches long, including their tails.įrazier Farms Exotics are both online and offline pet dealers that deals with *black squirrels as well. This process of natural selection determines whether the black morph will be successful in a particular region.Ī black baby squirrel is identical to a gray squirrel except for color. The color variations in black squirrels are a result of a genetic mutation that causes excessive pigmentation. This process occurs in several species, and these individuals are called ‘ melanistic’, which means ‘ melanin’ – a pigmentation chemical.
Today, the animals are seen in both their native home of North America, including sites as wide-ranging as Ontario, Washington, D.C.
Thanks to this latest round of testing, scientists now have a better understanding of the faulty gene’s origins.Īccording to Mental Floss’ Jake Rossen, black squirrels are relatively rare, constituting just one in 10,000 of the seemingly ubiquitous rodents. Published in FEBS Letters in 2014, the research demonstrated how a “tiny molecular switch”-in other words, a pigment gene missing a piece of DNA-can determine the shade of a gray squirrel’s coat. The new study builds on McRobie’s earlier findings regarding squirrel coloring. Although genetic similarities between fox and black squirrels appear to support this hypothesis, it’s worth noting that the scientists did not entirely rule out the possibility of the allele starting out in gray squirrels and later passing on to fox squirrels. Per Live Science ’s Rafi Letzter, the researchers pinpointed the emergence of black fur to a gray squirrel allele called MC1R∆24 this gene variant is “identical” to an allele found in darker-hued fox squirrels, leading the team to theorize that the color-changing mutation originated in fox squirrels but spread to gray squirrels through interbreeding. Sujit Kumar via Wikimedia Commons under CC BY-SA 4.0 To determine the origins of squirrel melanism, or dark coloration, McRobie and colleagues from Cambridge University and the Virginia Museum of Natural History extracted DNA from gray and fox squirrel specimens found in North America.īlack squirrels are actually just gray squirrels with a different shade of fur “The most likely explanation for the black version of the gene being found in the grey squirrel is that a male black fox squirrel mated with a female grey squirrel.” “People have spotted ‘mixed species’ mating chases, with a mix of grey and fox squirrels a female,” lead author Helen McRobie of England’s Anglia Ruskin University says in a press release. This gene variant, passed from fox to gray squirrels via mating, is the same mutation responsible for black squirrels’ coloring. As a new study published in the journal BMC Evolutionary Biology explains, squirrels sporting black coats owe their distinctive appearance to interbreeding between gray and fox squirrels, which carry a faulty pigment gene known to give some members of the predominantly reddish-brown species darker fur. Despite differences in coloring, eastern gray squirrels and so-called black squirrels are actually members of the same species.
