5 human siblings between the ages of 18-34 were found living together in an isolated village in Turkey. While it is odd that the siblings are still living together after all of these years, it isn't nearly as odd as the fact that they are all quadrupeds.
To quote the Yahoo News story: Researchers believe the five brothers and sisters, who can walk naturally only on all fours, may provide new information on how humans evolved from four-legged hominids to walk upright.
From the report it sounds like these scientists would sell their most loyal Erlenmeyer flask to study the siblings. But to me, learning about our humble evolutionary beginnings from present day humans is nothing new. If these scientists have a weakness for home made ice cream and a penchant for croquet, they can simply accompany me to one of my family reunions to witness various characteristics, appearances, and behaviors of pre-modern man.
