New study provides first evidence of non-random mutations in DNA | Live Science

selection, in which mutations give rise to adaptations that are passed on to offspring and alter their chances of survival. Scientists have assumed that these mutations were random and that the first step in evolution by natural selection was, therefore, also random. But this may not be entirely true, the new study suggests.

"The idea of random mutation has been around for over a hundred years in biology and is something you hear so often as a student that it is easy to take it for granted," Monroe said. "Even as a practicing geneticist and evolutionary biologist, I had never seriously questioned the idea."

The new finding does not disprove or discredit the theory of evolution, and the researchers said randomness still plays a big role in mutations. But the study does show that these genetic alterations are more complex than scientists previously believed.

Weather Update – January 20, 2022

It probably was good I left the heat up before going to work πŸ˜…

It’s going to be so cold again tonight but hopefully the heat will keep up as I turned it up in advance of the cold. 🌬 Going to want to leave those cabinets open before bed, and make sure I don’t trip over them in the morning. I would like to go for a walk this evening, but I don’t know, it sure looks raw. Maybe instead, I should do a stroll down to the library πŸ“š and get some books, before retiring to bed early. I will probably still walk down to the express bus in the morning 🚌 but it will be a brisk walk, with wind-chills in the negative territory in the morning. Probably knowing how this goes, by February it will be in the 50s.

Probably I wouldn’t mind the cold so much if I wasn’t paying for the heat, or having to wait for the bus in the cold. But my apartment is just not warm in the cold, and it’s just so miserable. πŸ§₯  In the summer, it might be hot, but I can get out of town on the hottest days, and the fan is relatively cheap to run. ☒

I know, in the summer I spend a lot more money on fuel, tires and replacing broken parts for my big jacked up truck, πŸ›» heading up to Adirondacks to beat the heat then what I spend on gas and electric even in the coldest weather, ❄️ but burning gasoline, having fires and drinking beer in woods 🍺 on a hot summer night is shit ton πŸ’© more fun then sending a check to the Nation’s Gird Corporation of the United Kingdom. πŸ”Œ
