Is evolution random?

Hiya,

Following on from yesterday’s post about noticing our environment below is an extract from a coincidental email that dropped into my inbox this morning – very thought provoking…

“Recent experiments have shown that living organisms can evolve quickly to adapt to changing environments. Environmental stress can trigger a response which speeds up the cycle of reproduction while making the reproduction of genetic material “deliberately faulty” in such a way as to generate mutations which may prove a better fit to the new environment. This backs up Stephen Jay Gould and Niles Eldredge’s theory of punctuated equilibrium, which views evolutionary change as something which happens in bursts with long periods of stability. It also shows that Jean Baptiste Lamarck’s original theory of adaptive evolution is at least as relevant as Darwin’s and Wallace’s later theory of natural selection to a complete understanding of the evolutionary process.

The key insight of Lipton and Bhaerman’s book is that we can be conscious agents of our own evolution. They make a comparison between human beings and cells. Each of us experiences our self as a single human being, but we are really a community of cells operating autonomously but cooperatively, the self-interest of each requiring the survival of the whole. Now we stand at a comparable evolutionary threshold to that which separated single-celled organisms from the first multi-cellular organisms. For certain single-celled organisms there was a survival advantage in grouping together in communities. Eventually these communities developed a membrane around them and became a multi-celled organism. Originally all of the cells were the same. Later the specialisation of cells within the community of the organism allowed for more complex development. As human beings we are grouped together as members of a society, but we are still working, to some degree, at cross-purposes. When these communication problems are solved we can work together, like our cells, as a single organism pursuing not just survival but “thrival” as Lipton terms it.”

  1. do think we are “adaptable”…our bodies become what we eat…our personalities become like people we are involved with…our ways become like where we live…
    So choose wisely if at all possible!

      Absolutely Marilyn, we certainly seem to be at least 50% nurture. So let’s be aware of what nurture we are giving and receiving. 🙂
