Uncommon Descent Serving The Intelligent Design Community

Researchers think they know how chromosomes came to exist

At Quanta: "Now, in a paper appearing today in Science Advances, an international team of researchers led by Daniel Rokhsar, a professor of biological sciences at the University of California, Berkeley, has tracked changes in chromosomes that occurred as much as 800 million years ago. They identified 29 big blocks of genes that remained recognizable as they passed into three of the earliest subdivisions of multicellular animal life." Okay, but all this information exploding such a long time ago… ? Read More ›

Templeton is trying to have agency, directionality, and function in life forms without underlying intelligence

Purpose statement: There is a growing recognition that biological phenomena which suggest agency, directionality, or goal-directedness demand new conceptual frameworks that can translate into rigorous theoretical models and discriminating empirical tests. Read More ›

Lockdowns Accomplished Nothing

I blew it when I predicted in 2020 that the Covid scare would be like the many scares before it, much hyped but not nearly as deadly as the fear mongers suggested it would be. But I was spot on when I pushed back against the lockdown being pushed by the Imperial College London crowd (which recommendations were ultimately adopted by most nations). So concludes a new paper out of Johns Hopkins University, “A Literature Review and Meta-Analysis of the Effects of Lockdowns on COVID-19 Mortality,” As summarized in National Review, the “paper starts by noting that “an often cited model simulation study by researchers at the Imperial College London (Ferguson et al. (2020)) predicted that a suppression strategy based Read More ›

At Mind Matters News: How do insects use their very small brains to think clearly?

Another strategy, one that enables social insects to engage in complex behaviors, is an established but little understood concept: The colony can have a memory that individual insects don’t have. Stanford biology prof Deborah M. Gordon, author of Ant Encounters: Interaction Networks and Colony Behavior (2010), recounts an experiment she did, to create an obstacle for ants and see if they remembered it. Read More ›

At Scientific American: Salamander “junk DNA” challenges long-held view of evolution

Douglas Fox at SciAm: The salamanders would be on death’s door if they were human. “Everything about having a large genome is costly,” Wake told me in 2020. Yet salamanders have survived for 200 million years. “So there must be some benefit,” he said. The hunt for those benefits has led to some heretical surprises, potentially turning our understanding of evolution on its head. Read More ›

Researchers: Moons make planets habitable — but not all planets can have them

University of Rochester: The researchers found that rocky planets larger than six times the mass of Earth (6M) and icy planets larger than one Earth mass (1M) produce fully—rather than partially—vaporized disks, and these fully-vaporized disks are not capable of forming fractionally large moons.

At Mind Matters News: The deadly dream of Human+ Look at the price tag…

Miller: In premises 1 through 5, human personhood is taken as a contingent property tied to the process of evolution. If these premises are sound, then the definition of “human person” can freely evolve with each new phase in the transhumanist program of self-enhancement. Read More ›

Everything is Coming Up “Non-Random”!

On January 12, 2022, Phys.Org had a PR on an article documenting “non-random” mutations found in wild tobacco plants, published by a team from UC Davis. Now, three weeks later (Feb 1, 2022), we have another paper, working with human populations in Africa, and which, according to a team from the University of Haifa, “surprisingly” turns up “non-random” mutations. From the PR on the first paper: The scientists found that the way DNA was wrapped around different types of proteins was a good predictor of whether a gene would mutate or not. “It means we can predict which genes are more likely to mutate than others and it gives us a good idea of what’s going on,” Weigel said.
