Yes, you read that right. America’s founding father has been shown by recent scholarship to not just have been a lawyer for slaveowners, but also to have owned enslaved people himself.

Yes, you read that right. Recent scholarship confirms irrefutably that he not only represented slaveowners as a lawyer, but also enslaved people himself.
Classifying Tigers
Did you know there are active debates about how many tiger subspecies there are? In the 1900s there were multiple subspecies classified by tiger’s appearance: fur length, coloration, striping, and size. With the advent of genetic testing new possibilities have opened up in deciding what to count as a species or a subspecies. In 1999, a genetic analysis suggested there were only 2 tiger subspecies. A 2006 skull study suggested expanding 1 of those into 3, or 4 subspecies total. A 2015 morphological, ecological, and molecular study pointed towards 2 subspecies again. Then a 2018 whole-genome sequencing study pointed towards six tiger subspecies.
Why does this debate matter (besides to biologists)? The answer matters a lot to conservationists. More subspecies means breeding programs have fewer candidates for each potential tiger mating, and fewer subspecies means more candidates. In other words, the number of tiger subspecies impacts how easy it will be for humans to create more tigers, and help combat wild tigers’ continued decline.
