Lamarck lives!

Is that a comment regarding the sentiment Smokin' Joe is demonstrating, or have I inadvertently suggested that the physical development of the parent is gifted to the child?

(Smokin' Joe pinged as a courtesy since I mentioned his name)

I was referring to an ongoing infection of a population, or resistance thereto. Similar to the resistance europeans had to smallpox, but the Indians did not, only affecting the ability of the species to interbreed. The separate populations may be separated by viral infection as well.

Inherited disease is not one of Lamark's ideas, iirc, any more than congenital syphilis.
