There are cultures who consume a lot of dairy, others consume a lot of tubers. Some go crazy on coconut, but is there any who consume a lot of their calories from eggs? If so, how is their health?
An interesting question because relatively modern agrarian production methods and genetics are really what allow us to enjoy a consistant supply of eggs, but there were traditional cultures with fairly high egg consumption, but almost all of them agricultural. The traditional French and Korean diets stand out to me as being relatively high in eggs.
Edit: also Filipino cuisine is very very high in eggs. I guess many of the Asian cuisines are, which makes sense considering that's where chickens originally come from.
Travelling all over SE Asia you become very familiar with the dominant power of the egg - including eggs with foetus growing in it in China... not quite ready to go THAT Paleo... It would be interesting to determine at what point all these cultures became so egg-domninant - possibly something to do with Hinduism/Buddhism gaining ground and the symbolism of the egg - but i'm just plucking that one out of the air...
I have read that northwest indians had access to large numbers of sea birds eggs seasonally. They stored the yokes in bull kelp capped with grease (probably bear or whale) for long term storage. The yolks would get thick as they dried. I imagine it was a pretty strongly flavored food. Even with this kind of storage they wouldn't get nearly as many eggs as we can. Also I would probably consider most of those cultures as horticulturists, depending on how far north they are.
