The research shows that the volume of this endocast closely tracks the number of intact odor-receptor genes an animal carries.
Bigger bulbs point to richer gene repertoires – and stronger sense of smell. That tight anatomical-genetic link opens a reliable window into the olfactory abilities of mammals across deep time.

What an interesting article! Thanks for sharing things like this, Robin. It’s fun to learn about our sense of smell (as well as that of other creatures).
Love articles lie this, thanks for posting it
Glad you both enjoyed it!
