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.
Talk about convergent evolution. And if the timing of the split is correct, 150 million years was the amount of time available, not half a billion years. … at least one species of tardigrade lights up as well. One wonders how exactly the individual species of tardigrade (water bear) began to do that. What was the time frame there?
At Popular Mechanics: It’s not just superficial shape that unifies the five evolved crab forms. The paper details neurological commonalities, shared circulatory systems, and more, while also detailing the organ and systems that differ in shape and size.
Eric Holloway argues that the evidence does not really support common descent, not the way Talk Origins believes and we were taught in school.
Most interesting: “Our results provide an intriguing example of inter-kingdom convergent evolution of animal and plant venoms with shared modes of delivery, molecular structure, and pharmacology.” Plants and animals are not so different after all.
Shedinger: But how could a similar series of mutations of the sort necessary to produce similarly structured eyes in different lineages occur so many times independently if the mutations are randomly produced?
