Re: [Vo]:How does evolution work without selective pressure
Not true in the slightest. Different people fall under different economic and social conditions that enhance or limit the ability to find a mate, intellectual development changes who CHOOSES to have offspring, which is an even bigger selective pressure (Idiocracy, anyone?)

People are a domesticated species, and domesticated species tend to evolve rapidly, I think. Evolution never works in reverse. - Jed

Alain Sepeda alain.sep...@gmail.com wrote: human, by losing many natural pressure (resuistance to disease, survival to pregnancy), For most of history we have been under pressure from disease, especially in Eurasia, where population density was higher and mobility east and west of people and disease vectors has been much higher than the rest of the world. This has had a major long term influence on Asians and Europeans compared to people in the Americas and the Pacific. That is the theme of J. Diamond's book, Guns, Germs, and Steel: The Fates of Human Societies The removal of major infectious disease just happened a moment ago in evolutionary terms. It has not had any effect on people yet. The differing effect of infectious disease in Eurasia versus the Americas lasted long enough to have some evolutionary consequences, according to Diamond. - Jed
Re: [Vo]:How does evolution work without selective pressure
Frank, It is called Variety. Look around you and you will see multiple types of trees, birds, people, etc. I think we are constantly being biologically mutated all of the time by the flux of Dark Energy flowing thru us and low energy nuclear reactions it can create with regular matter. Sometimes that mutation is an advantage, sometimes a disadvantage, sometimes it just adds variety, like skin color. Disadvantage might be a cancer or disease. Advantage might be a modified gene that gives better hearing. If dark/vacuum energy flux increases through us/Earth, it will weed out the weakest thru environmental pressures, like the next ice age, or very bad biological health. This is the weak anthropic principle at work. We currently live in an era of low vacuum energy and mild climate. I think that can change quickly due to the sun or comets increasing this vacuum energy in our space. That is just my interpretation Stewart darkmattersalot.com On Fri, Feb 1, 2013 at 12:02 PM, fznidar...@aol.com wrote: I have read many times about how we are evolving.

I think that selective pressures have changed in a meaningful sense. And they are not some of the ones above; consider, for example: 1. The ability to find a dress matching the marketing standards. This only holds for women who have good fashion. Fashion sense presumably falls on a gaussian distribution, and it is plausible that for every woman who chooses a man for his good fashion sense, there is a women who chooses a man despite, or for, his bad fashion sense. 2. The ability to resist a call late at night -- perhaps this is a reference to fidelity? It seems like infidelity would be where evolution would push people, but I haven't followed this question. 3. Hand-eye coordination goes back to the basic selection pressures. This is an interesting one, because it shows that even though selection pressures have surely changed for people in a meaningful sense, there are still the must-haves, so to speak. But I doubt that zoologists would say that people are under the pressure of natural selection in the same way the way that zebras or lions or inchworms are. Are there any zoologists here who can elaborate on this? Eric
