In honor of DNA day I’m doing the history of genetics! It will be ONLY The very early part. Hopefully it will teach people about how genetics works and how it got started! Btw. I know I’m late on DNA day, it’s been an extremely busy year so far! Also if you would like to learn more about the subject there are many books on topics of genetics. An easy to understand and fun to read book is “a cartoon guide to genetics ” by Larry gonick and mark wheels. It’s the one I read and where I remember MOST of this information from. It’s a good book for people with learning disabilities. The book goes WAY beyond what I’m covering. Up until recent day. It’s available on Amazon for about $10 which is dirt cheap.
Back in caveman days it was thought that everything was living. Trees, animals, rocks….. They also didn’t have an understanding of reproduction. They didn’t see a connection between reproduction and sex. It wasn’t until people started domesticating animals that people seen reproduction patterns….. Animals doing it and stuff! Then people discovered that it took a man and woman to makes babies. Then farmers began what’s called “practical genetics ” or what’s known today as selective breeding. The best sheep, goats, probably people……. Were mates so they could make the best of something. Seeds were also not immune. Farmers would “weed out” strains of seeds they didn’t like making only the best crops and planting only the best seeds. Early farmers didn’t know why pollen worked on plants. Around 800 B.C. They tried to use “magic” to help plants have sexy time! There’s a story out of the bible that tells about early genetics. In Genesis chapter 30 the story of Jacob and his father Laban. Jacob said he would watch over his fathers sheep. As payment for watching over them Laban said he could have the spotted sheep. But Laban wanted the all black sheep for himself. Jacob would strip willow rods till they were white and lay them by a watering hole. He was trying to “bring out the white” in Labans sheep with the rods. However Laban sheep produced spotted sheep anyway because of recessive genes ( not because of the rods).while Greeks had theory’s of heredity ( they wondered why children look like their parents). A philosopher named Socrates wondered why they don’t act like their parents. The Greek Doctor Hippocrates realized that men made semen. He also thought chicks did to! He thought that the semen went through the whole body….. There was finger, toe, nose, mouth, hair semen . Two index finger semen make the kiddo have fingers…. You get the point. While the seman was in the woman the ” semen battle began” if the fathers index finger semen won then kiddo would have his dad’s index finger….. If moms semen won the battle then the kiddo would have moms green eyes…. Then came Aristotle who thought all boys came from their fathers…… Etc…. In the Middle Ages spontaneous generation was founded. Example: maggots could come from rotting meat, frogs come from slim. An Italian man named Francesco redi did an experiment that slayed the idea of spontaneous generation. He put meat in two jars. One covered , one not. The one covered didn’t have maggots. The one that was not covered had maggots.then came along a scientist named Anton van leevenhook . He was the first to make use of the microscope. He discovered that fleas, fish, dogs and humans were sexual beings. He also was the first to see Bacteria. He also discovered the sperm cell. But he believed that each sperm cell had a tiny human in it. If it was a boy then they also had tiny humans in their sperm……. William Harvey studied the chick embryo and believed that all animals came from eggs. He called it ” ex ovo omnia ” which is Latin for out of egg, all. After dissecting deer he admitted he was wrong. Finally a scientist named Oscar hertwig observed that fertilization was the union of a single sperm and a single egg. Back to plant sex…… By 1700 the sexual nature of plants had been resolved by a scientist named camerarius.
