Uncommon Descent Serving The Intelligent Design Community

Novel RNA and peptide species thought to have sparked evolution of complex life

Researcher: According to the new theory, a decisive element at the beginning was the presence of RNA molecules that could adorn themselves with amino acids and peptides and so join them into larger peptide structures. "RNA developed slowly into a constantly improving amino acid linking catalyst," says Carell. (He talks about the emergence of "information-coding properties" as if that would just happen.)

UK Spectator: “Why is Canada euthanising the poor?” (Slippery slopes dept.)

April 30: Since last year, Canadian law, in all its majesty, has allowed both the rich as well as the poor to kill themselves if they are too poor to continue living with dignity. In fact, the ever-generous Canadian state will even pay for their deaths. What it will not do is spend money to allow them to live instead of killing themselves. As with most slippery slopes, it all began with a strongly worded denial that it exists. In 2015, the Supreme Court of Canada reversed 22 years of its own jurisprudence by striking down the country’s ban on assisted suicide as unconstitutional, blithely dismissing fears that the ruling would ‘initiate a descent down a slippery slope into homicide’ Read More ›

Richard Weikart on the non-religious racism that anti-racists ignore

Weikart: While researching my book, Darwinian Racism, I examined the websites and publications of many neo-Nazi, white nationalist, and alt-right individuals and organizations. What I discovered was that most white nationalists and white supremacists today embrace a social Darwinist version of scientific racism and vehemently oppose Christianity. Read More ›

Before dividing, cells toss out waste products

Researcher: "Our hypothesis is that cells might be throwing out things that are building up, toxic components or just things that don't function properly that you don't want to have there. It could allow the newborn cells to be born with more functional contents," says Teemu Miettinen, an MIT research scientist and the lead author of the new study. Read More ›

Result of “de-extinction” project not very encouraging

Researchers: Yet despite their best efforts, the scientists were unable to recover nearly 5% of the Christmas Island rat’s genome. Many of the missing genes were related to immunity and olfaction, two highly important functions for the animal. “It’s not just the irrelevant stuff that you’re not going to get back,” Gilbert said. “And so what you’ll end up with is nothing like what went extinct.” Read More ›

Casey Luskin asks: Can claims about punctuated equilibrium accommodate the scientific data?

Luskin: Punctuated equilibrium compresses the vast majority of evolutionary change into small populations that lived during shorter segments of time, allowing too few opportunities for novel, beneficial traits to arise. Read More ›
