Google's Doodle of American geneticist and biologist Nettie Stevens, in honor of her 155th birthday
Google's Doodle of American geneticist and biologist Nettie Stevens, in honor of her 155th birthday

Throughout history, scientists and many other people had debated how the sex of a human being - and other animals - is decided. In the 1800s, for example, many Europeans believed that the food a mother ate during pregnancy helped determine the sex of her baby.

But Stevens’ research proved that X and Y chromosomes are the deciding factor.

Her scientific research was groundbreaking. Yet she was not always given credit for the discovery. Another scientist, Edmund Beecher Wilson, found similar results at around the same time. He was most often credited with the discovery.

But on Thursday, it was all about Nettie Stevens. Her name was a trending topic on Twitter.

One Twitter user wrote, “I've never heard of Nettie Stevens before today. Thank you Google Doodle for giving her appropriate attention and respect.”

And that’s What’s Trending Today.

I’m Dan Friedell.
