Don't close this thread - we are not talking religion here! And those who disagree with your premises and conclusions are not "ignorant" - ignorance is to claim that you know everything! This is why I stated that we should stay on topic...Rollo Tomassi said:One very common mistake the home-schoolers make is that evolution isn't simply reliant upon a genetic cause. DNA does in fact mutate to increase variety in species, but the X factor will always be environmental changes that select in or out a particular variation. It's not survival of the fittest, it's survival of the species best able to adapt to a changed or changing environment. Up until the late Cretaceous period reptiles the size of your house littered the planet. At some point something dramatically changed the environment. While the details of that event may never be known, what is known is that anything with a body mass greater than a few hundred pounds died off in a very short period. The environment selected them out, not their DNA. The moths that were affected by the industrial pollution someone else here mentioned were similarly selected out. It was not due to some spontaneous change in their DNA to compensate for a color shift in their environment. The lighter moths were simply not eaten by predators as often as the newly de-camouflaged darker ones and therefore were free to breed more readily. DNA does not surrepticiously change in accordance to environment, environment delimits which DNA will replicate.
The problem I have with the creationist vs. evolutionist debate is that both camps are so polarized that neither is willing to give an inch. Creationists (see fundamentalist christians) see evolution as a threat to their belief system and have the natural backlash anyone with a strong ego-investment would. On the other side Evolutionists want to use natural selection, et. al. to verify their own intellectual positions and poke at the spiritual. Neither side wants to concede a point at any cost because it validates the other at their own expense. The evolutionist lacks the spiritual and the creationist lacks the scientific.
The answer is in between. I'm not stupid enough to close my mind off to the possibility of the meta-physical, but neither am I foolish enough to ignore what's empirically provable that's right in front of my nose. It's not people with questions that scare me, it's people who have none that do. Remain the perpetual student and you'll maneuver around zealots and extremists of all stripes.
Evolutionary motivations for behavior, etc. does not excuse one from accepting responsibility for the consequences of that behavior. Neither does the socially constructed notion of morality change the basic biochemical nature of the prompts for that behavior. This is the dilemma that LMS and the rest of the home-schoolers get a headache from. They assume an understanding, or an accepting of an evolutionary basis for behavior excuses a person from behaving in anti-social ways. The irony of this is that it's just the social nature of human beings that alters the environment that should select out certain behavioral traits. The answer is that nature and nurture go hand in hand, neither can deny the other's influence on a being as a whole. But hey, don't let that stop the ignorance, have at it guys - or at least until close this thread for being quasi-religious. It makes for some great comedy.
Evolution, at the macro level, as a fact, has not been proven nor demonstrated! You guys are discussing changes and mutations, but these are changes and mutations within a certain species but fail to explain the overall premise of evolution theory whereby a new organism is created from another source/species via mutations. Every species has a genetic code and changes and mutations happen within that genetic code, but it does not create a new genetic code. The question I'm trying to get answered is who/what created the codes in all species? Where did the genetic code of the sperm come from?Deep Dish said:The rationale behind evolution is self-evident and thoroughly demonstrated.
To keep everyone interested, I would like to keep this discussion at the general level and not just have biologists talk details at the micro level - the purpose of this thread was to discuss the origin of man!
The grand scheme of evolutionary theory has not been proven, because within their framework or premise of the theory, it takes millions of years to observe this at the MACRO level. And by scientific standards, if it is not observable then it cannot be proven. This is why they reject creationism - intelligent being - so by the same rationale they should reject evolution as well! BUT, they are teaching children in schools that we came from apes? Why so, if it has not been proven? This is what needs to be discuss!ed here!
