Jul 6, 2026, 10:46 AM@futurebird I have a vague memory of reading about some flea species that makes (small) environment based adaptations in *one* generation.
Mom-flea living in a tough environment, has baby fleas with a helmet like growth that makes them tougher prey.
@discobeez @futurebird in mammals it’s proven that gene expression is altered by the parent’s trauma and those changes last several generations. Maybe the mechanism is similar?
Jul 6, 2026, 12:25 PM@discobeez @futurebird that's wild. I was reading that grasshopper vs locust is a one-generation change too. https://explosion-scratch.github.io/locusts/
That's a dimorph, not evolution. Spadefoot toads can do it. If they are born under certain conditions they are carnivores, otherwise they are vegetarians.
Jul 6, 2026, 3:03 PM@MCDuncanLab @futurebird not sure anybody was talking about evolution :-)
Also, that's an interesting article!
