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.”
Convergent evolution
Blood feeding evolved independently about 100 times despite being a very complex trait
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?
Spiders and birds of Paradise use the same molecular strategy for mating displays
Convergent evolution
Two jellyfish genomes differ “as drastically as humans do from sea urchins.”
So there is no Darwin switch. Different jellyfish converge on moving around via different sets of genes.
Detailed bat and dolphin convergence in echolocation
Is this magic, design, or a miracle?, a friend asks
Move over, mammals. Spiders provide milk for their young too
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…
Convergent evolution: Psychology Association says killer whales share personality traits with humans, chimps
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…
Convergent eye evolution shows that evolution is “easy”?
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…
Why some birds are smarter than others?: They have larger brain structures that mediate information
From ScienceDaily: University of Alberta neuroscientists have identified the neural circuit that may underlay intelligence in birds, according to a new study. The discovery is an example of convergent evolution between the brains of birds and primates, with the potential to provide insight into the neural basis of human intelligence. “An area of the brain Read More…
Convergent evolution: Green blood evolved four times in lizards
From Louisiana State U: Green blood is one of the most unusual characteristics in the animal kingdom, but it’s the hallmark of a group of lizards in New Guinea. Prasinohaema are green-blooded skinks, or a type of lizard. The muscles, bones and tongues of these lizards appear bright, lime-green due to high levels of biliverdin, Read More…
Why a four-eyed fossil lizard is a problem for Darwinism
Yes, four eyes. From Gunter Bechly at ENST: Based on two fragmentary fossils, Smith et al. (2018) just described the new monitor lizard Saniwa ensidens from the 49 million year old Bridger Formation in Wyoming. Both known specimens surprisingly had four eyes! Additional to the normal pair of lateral lens eyes, and the usual parietal Read More…
Spiders evolving disguises separately, in parallel, are another problem for Darwinism
Spiders evolving disguises separately, in parallel, are another problem for Darwinism Not that one can directly admit it. From Catherine Offord at The Scientist: The Hawaiian stick spider has evolved the same three color morphs on multiple different islands in parallel, according to research led by biologists at the University of California, Berkeley. The team’s Read More…
Secrets of 520 million-year-old brain debated, raise conundrums
From Andrew Urevig at National Geogaphic: Contradicting some previous accounts, the team argues that this new evidence appears to show that the common ancestor of all panarthropods did not have a complex three-part brain—and neither did the common ancestor of invertebrate panarthropods and vertebrates. … That structure can be traced back through the fossil record. Read More…
Convergence: Fish develop a variety of strategies in order to eat other fishes’ scales
From ScienceDaily: A small group of fishes — possibly the world’s cleverest carnivorous grazers — feeds on the scales of other fish in the tropics. The different species’ approach differs: some ram their blunt noses into the sides of other fish to prey upon sloughed-off scales, while others open their jaws to gargantuan widths to Read More…
Spiders and ants independently developed baskets for carrying sand
From Nature: Desert spiders are master engineers A spider living in the Sahara Desert excavates its burrow by hauling out bundles of sand fastened with silken cords, while another carries sand balls in a ‘basket’ of its own bristles. … A similar basket evolved independently in desert ants, the authors note.More.
