Does popular understanding of evolutionary theory need more depth and nuance?
The concepts of co-evolution and the symbiotic relationship between an organism and its environment are both established and obvious. The growing body of information related to non-genetic inheritance is very interesting, but it's not really a broad "rethink" of the core concept of evolution.
Still, it brings forth a few concepts that don't really get out of the classroom and into the mainstream such as the roles of behavior and teaching on reproductive success. When the subject comes up in the coffee house you'll hear appeals to `intelligence` or `strength` as intrinsic traits. Many successful organisms accumulate advantages through life (e.g. knowledge, immunities, strength). Some of these accumulated traits can be passed to offspring (knowledge through teaching; immunities through mother's milk); others simply aid the individual in achieving greater reproductive success. This isn't new information nor is it surprising to folks with knowledge of the subject, but it is missed in a more secular setting.
Unfortunately, it's hard to get to even this level of nuance because the public hasn't got past "survival of the species" and "nature vs nurture."
