I thoroughly agree with your intelligent assesment Julia, of Richard Dawkin's writng style, and yes, one has to sift out his suppositions, but I found reading him an easy way to get a handle on the facts he uses to come to his conclusions, anything he quotes as fact cannot be in dispute or other scientists would have "strung him up" !
There are many other excellent books on the whole subject of Evolution, there is a not so old thread about them on here.
I am awating with excitement more understanding about early Hominids, such as the Denisvonians (spelling?) discovered in a cave in Siberia I believe, and genetically different to Neanderthals. There have been some more early Hominids come to light in China I believe, interesting stuff !
I am also interested in the evolution of the human mind/intellect. It seems that though huge leaps forward were made, tool making, using fire, then agriculture,the mind had not evolved enough to take on board concepts we find commonplace, and had not the ability to do "joined up thinking".
I think many in today's human race still do not think clearly, which gives us many of the problems we face.
The mind has some evolving to do, it is not generally yet fit for purpose. To be fit for purpose it would only seek ways to benefit the human race, at present most effort seems to be centered on finding ways of destroying it.
