Discussion Overview

The discussion revolves around the ongoing process of evolution, particularly in humans, and whether current societal factors, such as poverty and education, influence genetic selection. Participants explore the predictability of evolutionary trends and the implications of modern medicine on natural selection.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants question whether humans are still evolving and if this process has reached a peak or continues indefinitely.
  • There is a suggestion that modern medicine may reduce natural selection by allowing less fit individuals to survive and reproduce.
  • Others argue that while evolution is ongoing, it may not manifest significantly in humans due to societal factors.
  • Some participants note that evolutionary predictions are challenging, especially for complex organisms in varied environments, though simpler organisms may show predictable trends.
  • There are discussions about the implications of socioeconomic factors on reproduction rates and potential genetic selection, with some questioning the existence of specific "poverty" or "education" genes.
  • Participants express uncertainty about the relationship between genetic traits and socioeconomic status, suggesting that the dynamics of poverty and education are complex and not solely determined by genetics.
  • There is mention of historical trends in reproduction rates among different socioeconomic classes, with some noting shifts in who tends to have more offspring over time.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether current human evolution is occurring or how societal factors influence it. Multiple competing views remain regarding the role of genetics in socioeconomic status and the predictability of evolutionary trends.

Contextual Notes

Limitations in the discussion include the complexity of defining genetic traits related to socioeconomic factors and the challenges in predicting evolutionary outcomes in humans compared to simpler organisms.

I have read "pop" books from the experts.

Sean B. Carroll has addressed the role of DNA in his book, “The Making of the Fittest”. He even has an excerpt on the web.

Martin Kenneth Jones has written about:

Those educated in the new field of Bioarchaeology are probably aware of the work being done at …

The George Pitt-Rivers Laboratory for Bioarchaeology accommodates a diverse range of projects from various parts of the world.

I'm sure that evolution is still going on and that the researchers will be presenting us many surprises in the near future.

There was a snippet on a T.V. programme yesterday regarding hedgehogs.Unfortunately a lot of them get killed on U.K. roads because most of them. freeze when headlights are approaching.Apparently, however, it has been recently noticed that more of them make a run for it and avoid getting squashed.Hopefully this running reflex is passed on.Is this a nice example of evolution at work?
