Human Chromosome Number 2 were fused together about 200,000 years ago and it not clear what did this, but it gave us the human brain of logic, empathy and creativity. — “But what they’re showing is that we showed up about 200,000 years ago. Now there’s a little evidence that may have been back as far as 300,000. But the kicker is that we can now look at the DNA and reverse engineer it and say, what did it take to get where we are? And what scientists are now calling the smoking gun. And there’s still a lot of controversy around this is human chromosome number 2. Human chromosome number 2 is the second largest chromosome in every cell of the body. It’s got about 1200 or so genes in that chromosome. And just one of them, gene tbr number one, is responsible for most of the brain that we have for our neocortex. So our humanness, our empathy, sympathy, compassion, love, our cognitive abilities, the mirror neurons, all these kinds of things are because that one gene. Well, where this gets really interesting is where did chromosome 2 come from? And scientists have the answer, but they don’t like the answer because chromosome 2 is the product of a fusion. Proceedings from National Academy of Sciences. The volume Genetics says this very clearly. We conclude that the origin of human chromosome 2 is the product of an ancestral fusion of telomere to telomere.

Fusion of two pre existing chromosomes. That does not happen in nature. It can’t happen in nature.

So here’s what they’re saying. You got two fully formed, fully functional chromosomes, and on the end are the telomeres that protect those chromosomes when the cells divide. And that’s why they’re on the end, they take the hit. It’s a trauma in a cell when those chromosomes are pulled apart and some of the DNA doesn’t make it. So nature puts telomeres on the end to take the hit, so the good DNA remains intact, and that’s why it’s on the ends. Human chromosome two, those telomeres are right in the middle of the chromosome where they shouldn’t be, because those chromosomes were fused together about 200,000 years ago when we appeared”

Stars produce life ingredients

 

Massive Stars Are Factories for Ingredients to Life

NASA’s telescope on an airplane, the Stratospheric Observatory for Infrared Astronomy, has provided a new glimpse of the chemistry in the inner region surrounding massive young stars where future planets could begin to form. It found massive quantities of water and organic molecules in these swirling, disk-shaped clouds, offering new insights into how some of the key ingredients of life get incorporated into planets during the earliest stages of formation.

A similar process likely happened during the formation of the Sun and the inner rocky planets of our solar system, including Earth. The results are published in the Astrophysical Journal.

Illustration of a dusty disc rotating around a massive newborn star that’s about 40 times the size of the Sun. SOFIA, the Stratospheric Observatory for Infrared Astronomy, found the inner regions of two of these kinds of discs are filled with organic molecules that are important for life as we know it. These include water, ammonia, methane, and acetylene — which is a chemical building block to larger and more complex organic molecules — illustrated in the call out.

Life on Venus?

Fascinating new discovery of life in the atmosphere of Venus was announced today. Brian had previewed it on his blog.
