The Aquatic Ape: New evidence?

The Waterside Ape BBC Radio 4 Publicity Sir David Attenborough considers whether new evidence will help a once widely ridiculed theory of human origins move towards to mainstream acceptance. In 1960, the eminent Oxford marine biologist Sir Alister Hardy proposed a revolutionary idea: that our human ancestors had not started their existence on the wide savannahs of Africa, but had become accustomed to living alongside water – swimming and diving in the shallows, collecting the abundant food, and learning to…

The quantum / classical RNA-mediated ‘tipping point’

Researchers identify ‘tipping point’ between quantum and classical worlds Excerpt: “Any popular explanation of quantum theory usually begins with Schroedinger’s cat – a thought experiment describing a cat inside a closed box, that may be either dead or alive,” Vered says. “Rather than looking at the tipping-point between life and death, our experiment examines the point at which quantum behavior gives way to classical physics. Since quantum behavior kicks in at a very small scale, one could liken our results…

Removing natural selection; reshaping the horse; adjusting evolutionary theory

Prehistoric genomes reveal the genetic foundation and cost of horse domestication Reported as: Reshaping the horse through millennia Excerpt: “Domestication is generally associated with repeated demographic crashes. Yet, mutations that negatively impact genes are not eliminated by selection and can even increase in frequency when populations are small. Domestication thus generally comes at a cost, as deleterious mutations can accumulate in the genome. This had already been shown for rice and dogs. Horses now provide another example of this phenomenon.” My…

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…
