a bonobo humanity?

I’m just finishing off my third reading of On the origin of species, and hopefully I’m a little wiser. It’s likely I read it the first time, in Penguin Modern Classics, just to be able to say I’d read it – but unfortunately, nobody asked. Many years, perhaps decades later, I read it again, the same copy. I remember nothing about it, or the whys and wherefores. This time I’ve read it as part of the four-volume set, edited by James Watson, including The Voyage of the Beagle, which I very much enjoyed, and The Descent of Man and The expression of the emotions in man and animals, which I look forward to with some trepidation, due to the wealth of detail he presents, and the archaic language, which I struggle with. 

The thesis that Darwin presents, so threatening and generally offensive to the much more religious world of his time, is natural selection, or descent with modification. In presenting the thesis he had to provide a multitude of examples, from his own observations and experiments, to those of colleagues in the ‘naturalist’ world, many of whom – no doubt the majority – were hostile to that thesis. For those of us who aren’t naturalists or biological scientists, or inhabitants of the 19th century with its often out-dated nomenclature, this makes for difficult, though often enlightening, reading. And I’m left impressed with the detail of his analysis, the work he did not only on cirripedes (barnacles) and pigeons, but various plants, beetles, ants and bees, amongst other beasties. Reading his Beagle book, with all its descriptions of the wildlife and geology (and the ‘savages’) of South America in particular, was good preparation for this third reading – just as The Origin will surely prepare me for The Descent of Man, though I’m still feeling a bit daunted, pre-embarkation. First I’ll finish reading Janet Browne’s biography, which is a joy. 

I’ve been trying to process this wealth of detail, while being well aware that it’s only a fraction of what has since been discovered. Bats, as he notes, are able to inhabit, to carve out a niche for themselves, in islands far from other lands, due to their powerful flight systems, while other mammals are scarce in such isolated places, or are more unique in their anatomy. Island birds’ wings become vestigial due to a lack of predators and an abundance of ground vegetation, but why did they develop wings in the first place? Darwin hints at what we now know – that the Earth’s activity may have connected or separated today’s islands or continents, over a period of history far greater than was previously thought. His friend Charles Lyell’s geological observations were far from accepted at the time, though Darwin himself (doubtless influenced by the first volume of Lyell’s 3-volume Principles of Geology, which accompanied him on the Beagle voyage) found shell fossils in the mountain regions of western South America. Generally speaking, many of his researches raised more questions than answers, but those questions couldn’t be resolved by the accepted creationist model. Blended inheritance, from what I’ve read, tended to be his explanation for minute differences developing over eons, but this conjecture, I think, isn’t mentioned in The Origin. 

Darwin’s thoroughness, the multitude of examples he presents, are the best sign of his realisation that what he was presenting was revolutionary – ‘Darwin’s dangerous idea’, as Daniel Dennett termed it. Its impact, as we know, was massive, and somewhat negative at first, but it surely helped in the acceptance of the genetic thesis in the 20th century, and led to the greater scientific grounding of biology and biochemistry. Darwin’s doggedness, his unrelenting recognition of the importance of his theme, while recognising that so much more remained to be discovered, so many questions remained unanswered, gives the work a modern feel, though that’s often undermined by what we now consider archaisms, and the sense, accurate enough, that he was a wealthy amateur aiming his work at other wealthy amateurs (more or less exclusively male), who nevertheless held the future of science in their hands. The situation is better these days – somewhat.
