Convergent evolution

Talk about convergent evolution: Lizards evolved for life in trees at least 100 times

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?” Read More ›

Researchers: Spiders use the same cues as vertebrates in distinguishing living vs. non-living things

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. Read More ›

Interesting finding: COVID-19 populations show high convergent evolution

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. Read More ›

Convergent evolution: Our most distant relatives were sponges, not comb jellies, say researchers

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. Read More ›

American Museum of Natural History: Whale and hippo skin adaptations evolved independently

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." Read More ›

Odd: Koala fingerprints almost indistinguishable from human ones

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. Read More ›

Convergent evolution of cobra venom

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? Read More ›

Convergent evolution: Tasmanian tiger pups “extraordinarily”similar to wolf pups

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. Read More ›

In addition to other weird characteristics, the platypus has biofluorescent fur

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? Read More ›

Crabs evolved separately at least five times

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. Read More ›

What next? A tree that stings? Yes.

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. Read More ›
