A couple things: remember, fruit in ancient times was quite different from the fruit of today. A wild banana is different from a hybrid. There was a lot less sugar in all fruits before they were cultivated to produce sweeter and sweeter and bigger and bigger versions.
Saying that eating fruit is good because our ancestors ate fruit is like saying use processed vegetable oil because our ancestors had lots of fat in the diet. There's a big difference in the type and quality. All fats are not equal and all fruits are not equal.
Having said that, once again I think I should recommend a book that Shijing found and I read and was really impressed: "Cataclysm" by Allan and Delair. There's almost no way to talk about our evolutionary history without taking the data in this book into account. Just keep in mind that Allan and Delair seem to have conflated several events into one, and their timing is off by a few thousand years, but otherwise, the data they marshall to make their case is formidable.
