Ask Sam: that special time when scientists worldwide cringe as Sam & the team speculate wildly on a diverse range of topics before picking up the phone to call in the real experts. 
This time, we've got another hirsute mystery: Are insect and plant hairs also made from the magical (seeming) protein called keratin? Also, do bugs get cancer? And which came first: the chachalaca (not a typo) or the turkey? 
The Ask Sam Hotline (1-844-GO-OTTER) is always open, so do your best to stump the gang and send us down another figurative rabbit-hole!
