I've been reading Understanding Human Evolution, by Ian Tattersall, which is a recent summary of the research and is similar to his The Fossil Trail, which I read in 1995. This has been quite an active field, with new fossil discoveries, new archaeological techniques and new DNA analysis tools, and the still-fuzzy picture of hominin evolution seems to be advancing slowly, by the decade. Rather than summing up the contents of this book, I've decided to describe how and why I became interested in this topic.
In my case, I think that this has partly to do with the fact that my parents came from two different countries, and we moved from England to the U.S. in 1957, when I was seven. Growing up in a suburb of New York City, I had no sense of ethnicity, though I generally seemed to fit the description of a WASP, which was the dominant culture there. But the cultural environment was quite mixed at the time, with all of the job opportunities attracting people to the area. As I wrote earlier, there were already many Italian immigrants at the time, and, after World War II, others moved to the vicinity. I had friends whose parents had moved from the Midwest, and some of my friends' parents had met in Europe during the war: one's mother was from Czechoslovakia and another's was from Belgium. A girl in my class was from Norway. One family was Polish, and their son appeared in the 1963 film version of Lord of the Flies. Another family had moved from Australia after a divorce. At the time, I didn't think about this, and, much later, it came more into focus for me when "ethnicity" and "community" became buzzwords in the media: these had never been meaningful concepts to me. Although I've now lived in various parts of the country, I don't particularly identify with any region, though I seem to have a slight preference for the Northeast, perhaps because I grew up in New York.
After moving to the U.S., I never saw my English grandfather again and saw my English grandmother and Greek grandparents only once. I had very little contact with my cousins, aunts and uncles. By 1977, my father was already dead, but his mother was still alive, and I corresponded with her inquiring about family history. Her health was declining then, and she had her brother help me. He sent me some very basic genealogical information, along with a MacArthur clan tie, since his grandmother was a MacArthur born in Edinburgh. Shortly after this, my grandmother had a stroke, and she died in 1980. Since then, I've done a lot of genealogical exploration and know my English background fairly well, as far back as the eighteenth century.
The reason why I mention this is that much of what I discuss on this blog is related to human evolution, which, to me, is partly a continuation of my interest in genealogy. Evolution became an interest of mine when I read The Selfish Gene, by Richard Dawkins, and The Diversity of Life, by E.O. Wilson, in the early 1990's. I also studied Anglo-Saxon archaeology in Oxford in the summer of 1993. My overall conclusion is that you can only find out so much about your past, particularly your evolutionary past. It looks as if all of my ancestors were in Africa once, and later they left Africa, possibly returning, and probably mated with Neanderthals and Denisovans at some point. As research advances, it may be possible to know more about this through DNA analysis. As a practical matter, you can only speculate on what the daily lives of your ancestors were like just a few hundred years ago. I at least know what my great-great-great-great-great grandfather was doing in the eighteenth century: he was a farmer living in Aston Rowant, Oxfordshire. I've visited his grave and have a copy of his will. While, on the whole, I know very little about my ancestors, I seem to know more about them than most people know about theirs. Although, throughout my life I've never cared much about belonging to a group, everyone's true group consists primarily of their ancestors, whether they like it or not. As my father used to say, "Blood is thicker than water." Despite the fact that natural selection works through genetic variety, we probably have greater affinities to people who are closer to us both culturally and genetically. I wouldn't waste my time socializing with a gorilla. As someone who is now old enough to say that I grew up in a different era, I am often reminded that many of the people around me are living in a conceptual world far different from my own.
