Crows don’t have a prefrontal cortex so, as Offord notes, [the researchers] suggested convergent evolution (convergence on a common goal rather than common ancestry) as an explanation [for having skills similar to macaques’]. Even so, they say, the quality is probably innate. [Interesting, how often convergent evolution is invoked these days.]
Into what? Crocobirds? Smithsonian Magazine is anxious for us to know that they are NOT “living fossils.” They have evolved a lot, we are told, though admittedly they are evolving around in a circle. It would be interesting to know why stasis became such a threatening concept in some quarters.
I have recently posted a new video on my Intelligent Design YouTube channel. In this video I discuss several areas in the philosophy of science and modern evolutionary biology, and their relationship to ID. These thoughts were prompted initially by an interesting paper by philosopher of science Jeffrey Koperski ‘Two Bad Ways to Attack Intelligent Read More…
Of course, it’s even more unlikely to have all just happened by chance a number of times than just once. Nonetheless, New Scientist tries valiantly to ascribe it all to natural selection (acting on random mutation).
Toepads don’t evolve until after lizards get into the trees, not before. And padless lizards will leave trees at a high frequency — much higher than padbearing lizards. Okay, now here’s a question: How, exactly, does the tree lizard “evolve” toe pads just because they would be convenient? It’s not self-evident. Many lizards did not but others did. As Michael Behe would ask, “How, exactly?”
Researchers: Complex vision evolved independently in vertebrates and arthropods and so the ability to distinguish living from non-living motion using the relative positioning of the joints has most likely arisen convergently in the two groups of animals.
But wait. “Natural selection,” as usually understood, assumes ancestor-descendant relationships. That’s the point of it. If mammals “have clearly been taking pages from other play books,” how exactly, were they able to do so?
The house mouse, beloved of cats, only arrived in North America with Europeans, so there aren’t millions of years to make up a story about how things happened.
Researchers: We find that two particular mutation rates, G →U and C →U, are similarly elevated and considerably higher than all other mutation rates, causing the majority of mutations in the SARS-CoV-2 genome, and are possibly the result of APOBEC and ROS activity.
Re the researcher’s comment, “It may seem very unlikely that such complex traits could evolve twice, independently, but evolution doesn’t always follow a simple path,” well, he is virtually admitting that Darwinism stretches (snaps?) the bounds of probability but no one is allowed to discuss that honestly. That is most likely why there is a controversy in the first place.
Researcher: “Our latest findings contradict the current dogma in the field—that relatives of the amphibious hippo might have been part of the transition as mammals re-entered life in the water.”
If it washed up on the beach. The sea whip coral is technically an animal but you might not guess that.
Researchers compared the fingerprints of three koalas killed by cars, a chimp that died in captivity, and human ones. The koala prints were more like human ones than the chimp’s were.
Researchers: “This is the first clear example of snake venom evolving for defence, and provides a remarkable example of convergent evolution, or how natural selection can cause the same solution to a problem to evolve multiple times.” Sure, it all just somehow happens with no underlying intelligence in nature?
Researchers: While scientists have worked out that different animals evolve to look the same because they occupy similar places in the ecosystem, they have yet to explain how animals evolve to become convergent, particularly the forces driving their early development.
