There are some question I have about the mechanism that “they” say is operative in evolution. In the previous post, I talked about one possible scenario concerning how humans got here, the way we are today. Let’s call the bone swinging creature “bone killer”. Bone Killer was walking, creeping around for thousands of years, all the while being exposed to radiation from outer space. Maybe the ozone layer was thinner than than it is now. One day , a bone killer was zapped by some cosmic ray that changed his genetic code by one gene. Let’s say it was one that made his offspring able to fashion tools from rocks, instead of using jaw bones of animals. How was that passed down? Was it a dominate gene, and all changes in genes and chromosomes were of the dominant kind? Was there a female bone killer there with him at the time of the zapping and her eggs were changed at the same time? If that is the case, then those two, and those two only, would have been able to pass the gene for tool making down to their offspring. It seems rather far-fetched to me that the cosmic ray would change a whole population at the same time. If it was one male who was zapped and the gene was recessive, how long did his offspring have to wait for a female to have the same change is her genetic code? Could it have been thousands of years? It would be a near zero chance that the female would have the exact same gene changed so that the two could breed offspring and go on to be the stone tool makers. I have never heard or read yet exactly how the mutations could occur close enough together to make a difference in the population.
It still seems to me that chimpanzees are still chimpanzees and have been for thousands of years. I am surprised that no one has observed a genetic change in chimpanzees after all the furor over the depleted ozone layer. Humans have remained unchanged for thousands of years also. I have not read about any genetic changes in Japan after the two atomic bomb blasts. I know there were some horrible things that happened to some of the people exposed to the radiation from the those bombings. Yet, still, the Japanese people are fully human beings. No sudden change in looks, abilities, or brain power in the current population has been observed.
I understand about survival of the fittest, natural selection, or whatever you want to call it. I just do not see how the changes came about the way “they” say it happened. When I was a sophomore in high school, I took biology. There was posted on the back wall showing how all the different species of birds had adapted to their environment. The web feet fowls had adapted to water and the carnivorous birds had adapted to flying and catching other birds and animals. As I looked at the poster, in my ignorance, I thought, “All those birds could have been created to inhabit a certain environment”. A duck was created to paddle in the water and an eagle was created to fly to the heavens in search of prey. It is a matter of interpretation of the evidence, I suppose.
I took my wife to her painting society tonight. As I was leaving , I saw the couple in their powered chairs coming down the sidewalk. They are the two we saw in Biscuit Cafe a few days ago. I stopped the car to say hello, and then realized Bob had a problem. One of his drive belts had broken on his powered wheel chair. I parked and went to talk to him. He remembered me for the cafe. One his neighbors took out some screws, and I then installed the belt and reintalled the cover over the drive spocket. I was glad I was able to be there at the right time and lend a hand.
IT’S FOR THE BIRDS
I have to report that the tenants in condo #14 have been missing for about a week now. I just hope they found a better place to nest! Let’s hope a cat did not get them. The tenants in #15 are busy nest building, coming and going at frantic pace at times.
Last fall, my two neighbor ladies behind us planted 7 plants near the back fence under the maple tree. I am happy to report that 5 of the 7 plants have poked their little heads up this spring. I still have hope that all will be showing before too long. I will get pictures of them soon, and ask my neighbor what kind of plant it is.
