Sadness and science

Today is a sad day. I received a letter from the family of Dr Elaine Morgan, author of The Scars of Evolution and other inspirational books on human evolution, letting me know that Elaine died last Friday. She was 92 years old and had lived a wonderfully full life, so her passing is not a tragedy. But it is still sad that such an inspirational, intelligent, kind and humble woman is no longer with us.

She has been a tremendous inspiration to me. It was reading her books on the Aquatic Ape Hypothesis (AAH), and her ideas in the seminal “The Descent of Woman”, that led me to write Watermark. But it wasn’t only what she wrote that I found inspirational. Her bravery and dedication in taking on the scientific establishment in arguing the case for the AAH was a wonderful example to us all that there should be no holy cows in science. If science really is an objective search for evidence, then challenges to accepted thinking would be welcomed, you would think. But that wasn’t the case for Elaine, and her trials and tribulations in getting the role of water in human evolution taken seriously shone an interesting light on the difference between the ideal view of what science is, and how it is actually practiced.

The philosophy of science fascinates me. But that term, “philosophy of science” confuses some people. What is there to be philosophical about? Science is an entirely objective pursuit, surely. But, it is carried out by humans, so can it really be entirely objective? And, do we want it to be? Perhaps objectivity is a laudable goal, but maybe one that will never be achieved. In any case, there is something chilling to me about the idea of an entirely objective scientist, motivated only by evidence and not by an acceptance or understanding of the human condition (whatever that may be!). Elaine was motivated by the human condition. By the curiosity and wonder that is characteristic of our species. It may be true of other species, but we have no way of knowing that, at present. We do know it about ourselves, though.

There are four books that have had an enormous effect on my understanding of science:

  • “The Logic of Scientific Discovery” Karl Popper
  • “The Structure of Scientific Revolutions” Thomas Kuhn
  • “What is this Thing Called Science?” Alan Chalmers
  • “The Descent of Woman” Elaine Morgan

All four are fascinating, but of those four, Elaine’s book has had the greatest influence on me, probably because I’m a woman who, like her, had become heartily sick of the “man the hunter” theories of human evolution. Men stood up to hunt better, men made and used tools, men have strong upper bodies for spear-chucking etc etc. Women co-evolved as a side-product; they were relegated to picking up berries off the floor, making themselves sexually attractive to men and looking after the resultant babies. But what about this great big thing in our heads? That’s what really differentiates us from all other species on the planet. All the time our brains were evolving to be larger and larger, there was very little change in the tool sets we were making. Sorry, men were making. We just didn’t need all that brain power to bang rocks together a bit more accurately.

The arguments are very persuasive that our brains developed to accommodate language, and so it must have given us a significant advantage to be selected for so effectively. And with language came music and laughter and empathy and all the “touchy-feely” stuff which had been ignored in theories of what drove human evolution. We are fundamentally communicators, not hunters. Sure, we have to hunt and scavenge to survive. But many species do that very effectively in social groups; lions, wolves, orca etc.  You don’t need a massive brain like ours to do that well. And which sex is generally accepted to be more adept at language? I leave that question hanging 🙂

Elaine has been described as a “housewife” in newspaper and media articles many times, as if there is something truly amazing about looking after a family and being able to think outside the box. I agree with Elaine; humans have evolved the way we have because women were, and still are, adept at doing both.

Rest in peace Elaine. You lived a wonderful life.

  1. ‘there should be no holy cows in science. If science really is an objective search for evidence, then challenges to accepted thinking would be welcomed’

    My thoughts exactly but so often not the case. Those who question ‘the established consensus view’ are discredited by those who stand to benefit from a hypothesis being accepted as fact. Open minds are all to rare.
