Huh? It's part of the history of science. In this case attempts to explain the fossil record.
This whole excursion into Lamarck started when I replied to FreedomProtector:
He had posted If someone was to lift weights and increase their muscle mass, would genetic traits of bigger muscle would be passed on to their children? --the typical answer was an unscientific, yes...
And I replied:
I'm having a hard time believing this; are you claiming that the teacher was so awful that you couldn't tell the disproved Lamarckian theory from normal biology?!
Lamarck was, to say the least, speculating in an area where our current knowledge is so much superior that it's misleading to suggest that his ideas (or observations about ideas) were ever part of science.
Give it up. The guy's a fraud.
