Don't think I even knew this thread existed, though having said that someone will probably point out a post a I made .
I recently had a holiday in the north of Spain and visited a city called Burgos, home to a cathedral which is on the UNESCO World Heritage list. Burgos has a beautiful old town where the cathedral is situated. Well worth a visit.
Whilst I was there I visited their Museum of Human Evolution. Five floors of the history of mankind. This is a well laid out exhibition, luckily for us English speakers most of the exhibits are in both Spanish and English, though of course they offer the usual audio accompaniment in various other languages.
Two of the exhibits particularly struck a chord with me. Firstly the information about Neanderthals, many years ago I read about about them (The Neanderthal Enigma by James Shreeve) and since then I've found the parallels between them and us fascinating ( they took care of their sick and infirm and buried their dead) and been annoyed about we now use the name as a term of abuse. It is thought the last places they inhabited was Spain. I've always been struck by the idea of the last one, the last of his or her kind. Of course they wouldn't know they were the end of an evolutionary line. But to slowly watch all your family die and not know where anyone else of your kind were. To die somewhere completely alone. No one left to bury you. I can only imagine deep sadness as slowly hope of ever finding another again.
The other exhibit was a recreation of a brain. This was a large construction which you could enter and inside there were lights demonstrating what the electrical activity when thoughts or brain activity occurs. Each thought like a ticker tape parade cascading through the synapses, electrical fireflies, thoughts foraging fermenting. Miniature fireworks, sparks, speed of light dancing divesting directing a mesmerising collage of coherence.
