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?
In an “incredible” display of convergent evolution, sixteen different deep-sea fish developed extreme light-absorbing qualities, like a “black hole,” for camouflage amid bioluminescence.
Researcher: “The degree to which baleen whales and dolphins independently arrive at the same overall swimming adaptations, rather than these traits evolving once in the common ancestor of both groups, surprised us,”
Food for thought: “Weirdly, it’s easier for us to generate beautiful images of skulls than it is to know what these frogs eat,” Blackburn said. “Natural history remains quite hard. Just because we know things exist doesn’t mean we know anything about them.”
But still we hear, “There seems to be no more design in the variability of organic beings, and in the action of natural selection, than in the course which the wind blows.” Darwin, “Life and Letters,” i, p. 278 ? Hadn’t the Darwinists better change their story a bit?
So there is no Darwin switch. Different jellyfish converge on moving around via different sets of genes.
Is this magic, design, or a miracle?, a friend asks
Researchers knew that jumping spider (Toxeus magnus) young didn’t leave the nest for twenty-one days and adults were not observed to bring back food for them. So they checked it out: They looked more closely and noticed that the mother was secreting a liquid from its upper abdomen onto the surface of the nest, which Read More…
Using a five-factor test. Convergent evolution is cited: Researchers found that the personality traits of killer whales were similar to those of both humans and chimpanzees but more similar to chimpanzees. Killer whales were similar to chimpanzees and humans for the extraversion factor (e.g., playful, gregarious and sociable). Killer whales and chimpanzees also shared a Read More…
Here’s an inventive turn of phrase from Nature: “Eye evolution came easy for simple sea creatures Family tree shows that jellies and their relatives evolved eyes independently at least eight times.” Jellyfish and their kin have no brains and make do with rudimentary nervous systems. But an analysis now shows that these simple sea creatures Read More…
