At Ars Technica: Specifically, as the tardigrades sped up, they would transition between having five legs on the ground, then four legs on the ground, then three legs on the ground—just like insects and arthropods, despite a 20-million-year evolutionary gap between them. “
A fluke discovery. And we’ve only begun to scratch the surface of the remarkable stuff that’s out there.
The big mystery isn’t why early, easy escape would be an advantage but why birds and bats never found a way to do it. But we shall see.
Really, the only connection is that youngorum is another life form that grew very large in a comparatively short period of time. Maybe a number of unrelated examples will point to a general rule but the story doesn’t shed light on the peculiar history of whales.
Here’s a question: Given what we (hope we) know today about the origin and development of life forms, would anyone today propose neo-Darwinism (natural selection) in any of its forms as an explanation – if they hadn’t already had to accept it anyway in order to get to where they are today?
From introduction: [I]n Part 2 we look at the textbook examples of microevolution in light of gene sequencing. In every example of microevolution used to support Darwinism, mutations only degraded existing genes. No new genes were created. But without new genes, Darwinism is limited to microevolution.
Pushing back the time things could have happened just by accident (a million monkeys typing)… Researchers: “This is likely to be controversial, but we think, and hope, that it will spark some great conversations and it could lead to a change in our understanding of the ways body warmth is maintained.”
When they are explaining stuff like this, you have to know that they are not talking about Darwinian evolution. Whatever they may claim.
Of course not. The whole point was to pretend that nothing does.
We are told, “Data from 329 aerospace engineers and 72 neurosurgeons suggests they are not necessarily cleverer than general population”: Researchers examined data from an international cohort of 329 aerospace engineers and 72 neurosurgeons who completed 12 tasks online using the Great British Intelligence Test (GBIT) from the Cognitron platform, as well as answering questions Read More…
This find challenges the hypothesis that all snakes living across the world today evolved from extreme burrowers, because the vision genes lost in scolecophidians are present in most other living snakes. The researchers say it would be extremely unlikely for such genetic deficiencies to have been reversed through evolution.
Is the suggestion that octopuses “might be evolutionarily closer to ammonites than previously thought” another way of saying that a complex system developed much earlier than thought?
“It is interesting, just how crazily different it is,” says evolutionary biologist Mike Worobey of the University of Arizona, Tucson. Thought: Maybe lots of viruses are weird but we don’t pay much attention to most of them.
Takehome: Of course we can “see ourselves” as an earthworm. But it doesn’t work in reverse. And Pamela Lyon sheds no light on that fact, apart from denigrating humans.
“It’s remarkable that concurrent evolution occurred at the molecular level in all these animals,” said UCR evolutionary biologist and study lead Simon “Niels” Groen. “Plant toxins caused evolutionary changes across at least three levels of the food chain!”
