ORIGINAL: captiveplatypus yeah I still don't understand how you can't both be a Christian and think Evolution is possible. It is entirely possible. quote:
ORIGINAL: seeksfemslave Darwinian theory says that random mutations occur and if the resulting body types have advantage in the environment then that change takes hold. This would lead one to expect that all members of any given species would be approximately the same. Your expectation is incorrect. Nearly all mammalian species have a gene pool with many alleles. Exceptions are cheetahs and humans. Cheetahs are the most genetically homogeneous species of mammals. They might as well be clones. Humans are also genetically fairly homogeneous due to the Toba-extinction event 78 thousand years ago. quote:
ORIGINAL: captiveplatypus Say a Lion. All pretty much of muchness. ergo Natural Selection verified. Now lets look at human beings...... None of the positives above presented a great deal of advantage to the possesser or the species as humans came on the scene. In fact many possessing them verge on the edge of mental instability. How then did those qualities survive ? Lions have it easy. They have one specific function. As you yourself notice: humanity has many functions. As to these positives and negatives: it is a division into various qualities and functions - and sometimes the wage of sin, speaking from a spiritual point of view. It is like a see-saw: what is perceived as a deficit may in fact enhance another quality. quote:
ORIGINAL: captiveplatypus Incidently I assume large mammals have more complex genomes than small ones, The assumption is not correct. I have forgotten a lot and am not up to date, but the complexity of genomes is pretty much the same for sexually reproducing eukaryotes - whether they are mammals, fish, plants or algae. As to the size of the genomes, as you may have intended: I expect mammalian genomes to all have approximately the same number of genes: they all have similar organs that require the same genes to build them, after all. So size does not matter. On the other had: rapidly evolving species - thus not necessarily large species - like humans, may perhaps have more junk-DNA or perhaps duplicates of certain genes. quote:
ORIGINAL: captiveplatypus so size does matter when short time scale evolution is considered. If I am wrong, about genomes I mean,then I refer to the comment that chimpanzees share 93% of the genome with humans. Hope I am using the right technical term. What a difference that 7% makes. If you are not certain about the facts, then why speculate about it? I recall that the shared genome was 98 %. Anyhow, chimpanzees approximately have the same number of genes that humans do. It is just that two percent (or seven) of our genes are not shared. quote:
ORIGINAL: Daddy4UdderSlut Exactly... in general terms, this is an optimization problem, and the maximum rate of improvement in the solution in any short time interval, will be given by the slope of the function gradient at the current solution. That is about as clear as mud. quote:
ORIGINAL: Daddy4UdderSlut For those who find the preceding sentence clear as mud, what I am saying is, ges will happen with a speed that is limited by the incremental improvement in fitness from the current organism interacting with the current environment. That also is about as clear as mud. quote:
ORIGINAL: Daddy4UdderSlut In this example, although mammals existed for hundreds of millions of years before the ice age, there was no great advantage to being a mammal (and internally regulating body temperature) during the temperate period. Once the ice age came, the advantage in being a mammal was huge to avoid dying of exposure, and so mammals and variations thereof rapidly accelerated in their frequency and diversity. Then, as the huge dinosaurs died out, a niche opened up for larger mammals to overpower smaller mammals, and so those also became more prevalent. As I said, I am not up to date. However, when I was, I considered the arguments for homeothermic hot-blooded dinosaurs - high bird temperature - pretty convincing. Many dinosaurs probably did not sit on their eggs, but relied on the sun to hatch them. When the comet impact caused a "nuclear winter", the eggs did not hatch. Long lived poikilothermic (cold-blooded) reptiles like crocodiles and turtles could winter this 'winter', but the hotblooded dinosaurs could not. Birds did sit on their eggs, so those could hatch. Mammals had the advantage not to rely on eggs for reproduction. quote:
ORIGINAL: LadyEllen I sometimes think its a shame that those less well adapted to our society - those who could but wont get a job - are not bred out, leaving we stronger types to survive and prosper. It is a waste of human resources. Those people are deliberately trapped in their predicament by society. quote:
ORIGINAL: LadyEllen If God wants to get involved in this, then he will have to explain why these scroungers do so well in his intelligent design, when they are breaking not only many of his commandments but also many of the laws we have which spring from those commandments. Those people are the product of five million years of human evolution. As far as any biologist is concerned, they have the same worth as any other human being. You are clearly unaware of it, but you do need them. They have useful and superior qualities unsuspected by you. A deaf person will always consider ears useless as in his eyes they do not have any apparent function. Any characteristic deleterious to the species has long since been selected against and removed from the gene pool.
