Thanks for your valuable input I hate to say it but you are right The level of detail in both the lead and the main article are too much If History of biology can fit into K History of evolutionary thought should fit into less than K I will try and break out detail into child articles I can already see Evolutioanry ideas of the Enlightenment and Eclipse of Darwinism or perhaps just Alternatives to natural slection coming I also see a bunch of detail moving to transmutation of species and there is probably too much overlap with Modern evolutionary synthesis now as well You have given me quite a bit to chew on
