Emma Darwin, devoted wife and cousin of Charles, has written her first ever blog post, Emma Darwin - On the bi-centenary of the birth of her husband, Charles. She observes:
I am most comforted to learn that my husband's legacy has helped guide the development of cures for the deadly afflictions that ultimately took the lives of our dearest Annie and Charles Jr. and so many other innocent children.
Well said, Emma. Not all evolutionary study is purely descriptive: some of it has profound, real-word applications.
