Chimps Eat Crabs

Scientists have observed wild chimpanzees eating crabs, and hypothesize that aquatic prey facilitated brain development in early humans. 

I have seen diets based on what chimpanzees eat, and those are never complete.  None of them include insects.  Apparently, they're also missing crabs, tortoises, and monkey brains.  Let's say the diets are designed for charm rather than scientific accuracy -- although if you like the premise of eating like our close relatives, you can always adapt as we learn more about them.

Frogs Need Elephants

Elephant footprints provide breeding puddles and habitat connectivity for frogs, an example of the subtle and unexpected ways that species can interact.

This makes me wonder how much damage has been done to North America, which has lost almost all of its megafauna to humans. Horses, bison, wolves, grizzlies, etc. are confined to small areas. The mastodons and ground sloths are long gone. (They were so delicious.) We've seen that reintroducing even one keystone species like wolves can have tremendous effects. Occasionally, humans manage to replace a missing piece. How is a lawnmower like a bison? It cuts the grass so birds can forage for seeds and bugs, although regrettably it provides no other benefits such as fertilizer, meat, or buffalo robes. Ghost trees still make fruit and thorns for mammoths and ground sloths. It's the shifting baseline problem; we have a hard time seeing what isn't there.

Learn to look for the missing pieces.  And observe what's there while we still have it.
