I find some of the original ideas in this thread intresting, Like the heart thing. If both parents have synthetic hearts where will the offspring get the genetic coding to make an organic heart, while that depends where the parents got the synthetic hearts like if they were born with real hearts and had them replaced then their reproductive cells will still have the genes to make a heart even though the organism doesn't have one, it originally did. But if both parents were born without hearts for some reason, then it may be a recessive trait and the offspring may inherrit the domminat trait of having a heart from the grandparents, but if several generations in a row didn't have a heart it is probabal that the offspring will not have a heart, even thought that seems completly illogical because we need our hearts where as we don't need our wisdom teeth. But hypothetically if such a thing did happen we would have to rely on our technology for our survival, thus the synthetic hearts. |
Good points... well taken.
Now the whales apparently developed a new way of breathing that is somewhat different then what they used when they were still land animals. (swamp critters).
That change had to happen before they could live completely as ocean animals, and not like a seal or whatever. If environmental changes forced such a transformation then logically I would think that the changes did not take thousands of years, because from what I gather climate changes happen rather quickly.
We might have such a thing as rapid evolution as well as long-term evolution. I do not know if science has concidered that as a possible yet. (other then when it comes to micro-organizems such as those that cause flu or AIDS.)
When I said "confused" I was suggesting that perhaps the DNA would evolve another way to pump blood through the body that is of a different design then that of our current heart. Or a different kind of heart (altered design).
Hmm? We might evolve a heart that can filter out what causes heart attacks, or harmones that act like Oat Meal to thin out the blood to prevent heart attacks?
Now I will make a radical statement - evolution is all about our DNA learning new tricks to help us survive. DNA is like an Intelligent Designer with it's eye on the future. ( I am going to get into trouble for saying that - perhaps ). DNA learns from experience and feed-back from what is happening in the body.
But I just got that idea a moment ago and so it needs more time for confirmation purposes.
