Northwestern scientists also discovered in their research that Boule appears to be the only gene known to be exclusively required for sperm production from an insect to a mammal. "This is the first clear evidence that suggests our ability to produce sperm is very ancient, probably originating at the dawn of animal evolution 600 million years ago," said Eugene Xu, assistant professor of obstetrics and gynecology at Feinberg. "This finding suggests that all animal sperm production likely comes from a common prototype." Read more... Link to comment Share on other sites More sharing options...
