Homo sapiens ancestors likely had year-round access to fruit until relatively recently in human evolution.

“our homo sapien ancestors do appear to have arisen in equatorial africa and stayed there until maybe 60 70 80 000 years ago and there in the equator there's fruit all year round depending on what type of fruit when it's coming into season i live near the equator now and i can tell you firsthand that different times of the year different types of different types of fruit become available so some people will say but paul we didn't have access to fruit year round pretty sure we did up until pretty recently in human evolution and humans seem to do well with fruit year-round if you want to do fruit seasonally that's fine but i think that most of us can do well with fruit year-round and probably would have sought fruit year-round based on our equatorial origins in the past”
