Biologists puzzled by evolved RNAs and decaying DNA

Horizontal Transfer of Entire Genomes via Mitochondrial Fusion in the Angiosperm Amborella (December, 2013) Excerpt) “The ancestral angiosperm-wide genome duplication apparent in the Amborella genome not only serves as a genetic marker for the origin of extant angiosperms, but it may also have set in motion a series of events as numerous genes evolved novel functions, eventually leading to modern flowering plants.” See also: The Amborella Genome and the Evolution of Flowering Plants Excerpt) “Evolution of Small RNAs More than…

Complex behaviors of cell types in cancer

Decoding the emergence of metastatic cancer stem cells Excerpt: “By applying a physics-based approach to understand the dynamics of cancer decision-making, we were able to explain a number of recent experimental observations, including some that seemed contradictory.” My comment: The logic of the physics-based approach links physics, chemistry, biology, and math, etc. to conserved molecular mechanisms at the same time theorists tout their pseudoscientific nonsense about “mutations.” See, for example: Cancer’s deadly mutational tug of war Excerpt: Mutations are either…

In theory, or supported by experimental evidence?

Carl Zimmer typically makes statements like the one below without prefacing them with “in theory.” That’s how he establishes the bias towards evolutionary theory in nearly everything he reports. For example: “During the development of eggs and sperm, each pair of chromosomes swaps pieces of their DNA. Over the generations, long stretches of DNA get broken into smaller ones, like a deck of cards repeatedly shuffled.” Inaccurate statements like that one make it appear that the evolution of biodiversity occurs…

It’s cell type differention, not cell fate determination (2)

See: It’s cell type differention, not cell fate determination High-throughput engineering of a mammalian genome reveals building principles of methylation states at CG rich regions Excerpt: “…deviation from the derived models is a characteristic hallmark of methylation changes associated with cancer states suggesting that this phenomenon is mechanistically distinct from differentiation related methylation changes.” My comment: The article helps to detail the difference between facts about the molecular mechanisms of RNA-mediated events that lead to cell type differentiation and theories…

No excuses: Creation and the meaning of organismal complexity

E.O. Wilson On ‘The Meaning Of Human Existence’ Excerpt: “We’re one species — glorious though we are — we are just one species out of an estimated eight million,” Wilson said. “At the present time, we only know almost exactly two million species — enough to give them a scientific name. Six million species are out there, maintaining the planet for us as an autonomous ecosystem and stabilization system. Book Excerpt: ‘The Meaning of Human Existence’ “Six million species are…

No understanding of biodiversity

No single explanation for biodiversity in Madagascar Excerpt: “The study is part of a larger body of research aimed at identifying the climate, geology and other features of the environment that help bring new species of plants and animals into being in an area, and then sustain once they’re there.” My comment: Like many studies, this one posits that new species automagically arise and are somehow sustained in ecological niches. Excerpt: “What governs the distribution of, say, a particular group of…

2014 and 2004 Nobel Prize in Medicine

2014 Nobel Prize in Medicine is Awarded for Discovery of Brain’s ‘Inner GPS’ Excerpt: “… gray lines show the path followed by a rat as it moves around a box looking for pieces of food.” 2014 Nobel prize in physiology or medicine for finding brain’s ‘you are here’ cells Excerpt: John Stein, professor of physiology at Oxford University, said: “This is great news and well deserved. I remember how great was the scoffing in the early 1970s when John first…

RNA-mediated genetic engineering (Part 2)

WATCH: Bill Nye the Science Guy predicts end of creationism is nigh Excerpt: “Best known as Bill Nye the Science Guy, the 58-year-old educator, TV personality and author lamented the lingering myth that the universe is a product of divine creation.” My comment: Evolutionary theorists have not described a biologically-based evolutionary event that links one species to the evolution of another. The myth of evolution was exposed via the fact that Richard Lenski’s bacteria and Michael Desai’s yeasts did not…

RNA-mediated events are not a matter of faith

A Matter of Faith—movie review Highlighting real world problems for Christian families By Gary Bates Published: 25 September 2014 (GMT+10) Excerpt: “Parents need to be aware that they must deal with this issue of origins in the home because public education is not neutral when it comes to origins. The fact is university campuses today are really churches of atheism because they teach a materialistic view of our origins.” My comment: Until recently, I thought ‘churches of atheism’ was too harsh…

Color vision refutes the evolutionary dogma of gene duplication

The Rainbow Connection Color vision as we know it resulted from one fortuitous genetic event after another. By Kerry Grens | October 1, 2014 Excerpt 1: “The fact that we have the same few amino-acid substitutions as New World monkeys argues there was a single ancestral variation that gave rise to [the cone opsins of] both Old and New World primates,” Nathans says. “It leads to an interesting twist on the evolutionary dogma of gene duplication.” My comment: The fact…
