If you aren't interested in Lamarckian evoloution you probably shouldn't bother reading this post
Dogtooth and I were in the taproom of the Cid and Aleph (a soulless chain pub we had been forced into by contingency) and the conversation was flagging. Suddenly Dogtooth seized one of my stray tentacles and tugged urgently upon it.
'Look' he hissed, 'isn't that disgraced Lamarckian biologist Paul Kammerer?'
'I don't see how it can be' I muttered, but he was already up and walking over. I followed a little way behind.
'You're Kammerer aren't you?' he said.
'I don't know this Kammerer you are talking about' said the accused party in a thick Viennese accent. I was ready to retreat at the sturdy rebuff, but Dogtooth pressed on, revealing a previously unsuspected streak of steel in his character.
'Yes you are, you fraudulent rascal. What happened, I thought you killed yourself?' The man sagged visibly in his seat.
'It's true. I am he. When my fraud was discovered I felt I had no choice but to shoot myself in the head with a pistol. There, according to scientific orthodoxy, it should have ended. However, a few days later I woke up with a cracking headache in a small wooden box. As I lay there in my coffin my mind worked furiously, and I remembered that my father had once been shot in the head in a hunting accident, but had survived thanks to receiving excellent medical attention. Clearly he had acquired an ability to survive shots to the head, and passes it on to me. I cried out loudly, and the strength of lung which my mother had acquired while shouting at passing traffic stood me in good stead. A wandering onion seller heard my cries, and dug me up. I escaped from an Austria in turmoil, and settled in South London. I have lived in secret until this moment.'
'You say you acquired a resistance to being shot in the head?' I asked. 'By what mechanism?'
He didn't seem to have any answer to this, and we were in the verge of walking away in disgust, when who should walk in but Karl Jung.
'What a coincidence' Dogtooth remarked.
