Document Summary
We have all evolved from ancestors that have expected much more from out planning, priorities, etc. Message/science of darwinism contradicts what we have evolved to wish for ourselves. We are creatures of culture and what we experience in our environment. Out motivations and behaviour are completely empty when we are born: there is nothing in our minds yet that determines who we will become including our personalities, motivations, etc. Human motivations and behaviours are partially influenced by gene inheritance. How do we always have genetic variation: mutations: environmental impacts (chemicals, etc. ) and random mistakes in replication, sexual reproduction effects a collection of traits, genotype x environmental interaction. You always have traits that can be effected by the environment (physical, chemical and biological) but you will also have traits effected by genes. Natural selection acts on traits not genes that are effected by genes.
