Is a vast variety of new cichlid species in ten million years a “burst”?

One can talk about the cichlid "burst" that lasted ten million years but now, the term “explosion” has become politically incorrect usage to describe the Cambrian because shut up. Read More ›

At New Scientist: Questioning the idea of species

Denyse O'Leary
November 12, 2020
Darwinism, speciation
It's good news that they are thinking this way. If we’re going to vote money and legislation for environmental protection, we do need useful working classifications. Why waste time, money and energy “saving” a “species” that doesn’t really exist as a separate entity when some whole ecologies are critically endangered? And it doesn't matter how we choose to classify the "species" within them. At least these are more constructive discussions to be involved in than attacking or defending Darwinism. Read More ›

(Reformed) New Scientist 12: Evolution favors some outcomes, not others

Darwinism, Intelligent Design, speciation
So “Each lake contains many different species that show striking similarities in the variety of body shapes to species in the other lake, despite being more closely related to those living in their own lake” but “These body shapes adapt species to particular niches or diets, so must have evolved by natural selection.” But wait! The traditional argument for natural selection acting on random mutations (Darwinism) was that the species WOULD BE similar to more closely related species. If they’re not, … Read More ›

The Economist: Hybrids have “upturned” evolutionary theory

At The Economist: "These findings muddy Darwin’s concept of speciation as a slow and gradual process. Biologists now know that in the right circumstances, and with the help of hybridisation, new species can emerge and consolidate themselves in a mere handful of generations. That is an important amendment to evolutionary theory. " Read More ›

Researchers: How two bacteria of different species become one

Researcher: “They mix their machinery to survive or do metabolism, and that’s kind of extraordinary, because we always assumed that each and every organism has its own independent identity and machinery,” said Papoutsakis. Read More ›

Hybrid pet cat bred from species as different as humans and chimpanzees

Or so they say. Working on a story about unusual facts about cats, I (O’Leary for News) came across an interesting piece of information from a NOVA documentary: CARLOS DRISCOLL: All domestic cats, up until the last 20 years, have been purely Felis silvesteris. Humans have, very interestingly, now hybridized the domestic cat with a completely different species. NARRATOR: Anthony Hutcherson has been breeding one such hybrid, the Bengal cat. ANTHONY HUTCHERSON (Winn Feline Foundation): Bengals come from a cross between domestic cats and a wildcat species called the Asian leopard cat. Personality-wise, they are a little different from other cats, and they’re pretty active and interested and intelligent. So, if you just want a cat to sit on your Read More ›

“Astounding”hybridization between species of angelfish

August 4, 2020
Intelligent Design, speciation
At Phys.org: Other hybrids were found between species with over 12 percent pairwise distance in mitochondrial DNA. Pairwise distance is a measurement of differences in pairs of DNA sequences. "This genetic separation is quite astounding, considering that hybrids are rarely reported between species that share more than 2 percent in genetic distance," Mr Tea said. "Though coral reef fish hybrids are common; they are usually formed by closely-related species." Read More ›

New paper poses a serious challenge to the schoolroom Darwin industry. You know, one day, the study of evolution might be interesting, like the study of history. Prying the Darwin lobby and its propaganda loose from positions of power is a necessary first step. Read More ›
