In a major study published last month, scientists came up with a creature they believe was the evolutionary precursor of all placental mammals -- the biggest group of mammals, and the one that includes humans, horses, whales, bats, and many more.
But because the bug-eating, shrew-like creature is a hypothetical computer simulation, rather than found via fossil specimen, it can't receive a scientific name. And -- as this writer can say from experience -- "earliest common placental mammal ancestor" doesn't really dance off the tongue.
So here's your chance to name grandaddy shrew.
They're asking readers and listeners to tweet their naming suggestions to @Radiolab or @AMNH with the hashtag #nameyourancestor, or email them into email@example.com. (Include us with your suggestions and we'll retweet the ones we like too -- @Star_foreign and @katecallen).
The deadline for submissions is March 5. Here are some of our favourites so far:
