Researchers: Unusual island life forms may have been genetically pre-coded to vary

"Choi et al., publishing in PNAS, have proposed a very un-Darwinian account of how “spectacular adaptive radiations” occur on oceanic islands such as Hawaii. This has been a “paradox of evolutionary biology,” they admit. Maybe the diversity is an outworking of “ancient polymorphisms” of ancestors with a rich gene pool." As a hypothesis, it has everything going for it but Darwinism. Read More ›

Researchers: "It is not just that angiosperms are species-rich, but many individual angiosperm families show more morphological variety than all other seed plants combined, a distinction that reflects the dynamics of their genomes." An episode we never heard before from the history of life. Is this the new Cambrian Explosion? Read More ›

Another issue re the origin of plants between 3.4 and 2.9 billion years ago…

Evolution, Intelligent Design, Origin Of Life, Plants
Timothy Standish: I couldn’t help but notice that the time photosynthesis is supposed to have evolved doesn’t line up with either the time when oxygen is supposed to have become an important element in the atmosphere, half a billion years later, or the time that fixed carbon begins showing up in the fossil record, which is much earlier, possibly over half a billion years.

Researchers say they have a “precise estimate” for the time of origin of photosynthesis

Botanist Margaret Helder writes to comment “The point to reflect on is what all those heterotrophs did for food prior to the appearance of the autotrophs. Any organic molecules in the environment would be quickly digested if there were only organisms around with no capacity to reduce carbon.” Read More ›

Stanford: Plants evolved complexity in two rapid bursts — 250 million years apart

Researcher: "The most surprising thing is this kind of stasis, this plateau in complexity after the initial evolution of seeds and then the total change that happened when flowering plants started diversifying," said lead study author Andrew Leslie, an assistant professor of geological sciences at Stanford's School of Earth, Energy & Environmental Sciences (Stanford Earth). "The reproductive structures look different in all these plants, but they all have about the same number of parts during that stasis." Read More ›

The big story here isn’t about the disconnect between molecular and fossil data; it’s about how early on more complex life forms got started (all that complexity in such a short time isn’t looking good for random mutations). Read More ›

At Science: "Other bird species may also respond to “calls” from injured plants, recent evidence shows. Two European birds, the great tit and the blue tit, locate insects that are attacking pine trees by detecting the volatile chemicals the stressed trees release ... " Read More ›

Well, that’s good news for the hope of finding life on other planets! But researchers hoping to rush in and save Darwinism should know that if the earliest organisms could photosynthesize, an intelligent origin of life is virtually certain. Read More ›

So what becomes of all the Darwinian casuistry around “fitness” and “costly fitness” if things can happen so simply as this? The article emphasizes the benefits of studying “evolution.” Indeed, but that can’t mean fronting Darwinism 101 any more. Read More ›
