This is a lot of fun. Plug in two species or taxa and TimeTree will give you our best estimate of when they last shared a common ancestor. Drawing on a multitude of sources, you can look through the database and use TimeTree as a launching pad for further research.
- Dogs and Cats, 57.5mya
- Dogs and whales, 82.8mya
- Whales and sharks, 523.1mya
- Dogs and oak trees, 1407.8mya
Fun suggestion – play the ‘higher or lower‘ game with pairs of taxa.
