Ectrodactyly is a condition in which children are born with claw-shaped hands and/or feet due to their being born with missing digits. It is sometimes referred to as ‘lobster claw syndrome.’ The image at left is of a family sharing this genetic condition. It appears to have been taken in Spain in 1930.
When I was much younger, I read of a tribe in Zimbabwe, Africa where about 1/4 of the population had this condition. I remember how their condition intrigued me even then. Because it was against tribal law for people to marry outside the tribe, many of the Vadoma people had ectrodactyly. You may read a little more about them here.
This video is fantastic, easily understandable and well explained. Thank you, it’s a great help to my grade school son.
