I am writing an essay for Biology tonight, and I would like help ASAP?

This is the prompt... "I would like you to discuss the impact of language and culture on the principles Darwin set out in 'the Origin of Species.' This short essay should deal with the affect that Homo sapiens have had on human and non-human evolution by natural selection. Also, consider how the evolution of non-instinctual thinking (culture and reason) in primates like us may affect the future." sooo... ANY HELP AT ALL WILL BE GREATLY APPRECIATED (:
