Biological evolution has been traditionally viewed as due to mutations in genes. However this kind of evolution can require hundreds of thousands or millions of years to take hold Now we know that evolution can happen much faster, in as little as a few generations. Further, I see the human species as evolving very fast in the direction of longer lifespans, with the average lifespan from birth in the US and advanced countries increasing about 4 hours each day that goes by.
Please view this short video segment. And then comment on us humans evolving to live longer. And also comment on how interesting and useful you find this video kind of communication compared to the usual text-based blog entries found here.
I have suggested that the rapid kind of evolution involved is epigenetic evolution which moves far faster than Darwinian genetic evolution. It is the kind of evolution that has allowed us to grow taller in just a few generations and that is leading to our ever-longer average lifespans. See the blog entries US falling behind in longevity increases – why?, Social evolution and biological evolution – another dialog with Marios Kyriazis, and a more-technical presentation Stochastic epigenetic evolution – a new and different theory of evolution, aging and disease susceptibility.
This blog entry and several subsequent ones including short video segments on longevity science are being brought to you in close collaboration with Robert Kane Pappas. Pappas is the filmmaker who produced the recently-released film To Age or Not to Age. Pappas captured hundreds of hours of interesting video in shooting the film over a 4-year period, including extensive interviews with a number of prominent aging-science researchers. It was possible to incorporate only a small fraction of that interesting material in the film itself. However, Robert will be identifying short interesting segments of materials both in the film and not in the film, and I will be remarking on them just as in this blog entry. The same videos and my same remarks will appear on both this site and on the film site To Age or Not to Age.
Readers/viewers – please share your reactions in comments. What do you think are the implications of us living longer lives? Are we like the opossums? And what is your reaction to this kind of blog entry? Would you like to see more of them?
