Science, Creation & Evolutionhumans run to scavange???Thanks Not on this forum but on others, as well as watching/reading others debate on other forums. Because that is what evolution revolves around, the frequency of alleles in a gene pool. The frequency is affected by the reproductive advantage or disadvantage it gives the organism it is in. I have no idea I meant the age at which we are able to reproduce and have offspring (puberty onwards), whith out long legs ancient "humans" were still able to reach this age, have offspring and thus continue surviving as a species. Possibly, though the increase in leg length was probably not sufficent to make them think "freak" and also remember the looks wasn't everything, an individuals ability to gather food is also a factor. Also think about many of todays models, ever notice that many of them have unusually long legs. However anythoughts into what was attractive to ancient humans is mainly speculation. Why would this lead to less sucsessful mating? Also remember that we are talking about the length of the legs in relation to the body, this means that the natural variation in body mass and size of the "shot-legs" would cause this same problem (big mates with small) For several generations there would be more short legs but because the long legs on average have more offspring this difference in numbers would slowly decrease. Its all about the number of offspring they have, if they have more offspring per person than those with a competing allele they will increase their percentage of the population. Possible but unlikely, such groupings and systematic "persecution" would require a level of organisation that was beyond the ancient humans. The difference in appearance between a long leg and a short leg was probably not very major, maybe a few centimetres at most, not enough of a difference to cause one group to systematically wipe out another. Such organisation is a recent trait which led to us creating civilization, government, organised religion etc. |
