Bird, tested and released, turned out to be a hybrid of three species

From ScienceDaily: Scientists have shown that a bird found in Pennsylvania is the offspring of a hybrid warbler mother and a warbler father from an entirely different genus — a combination never recorded before now and which resulted in a three-species hybrid bird. This finding has just been published in the journal Biology Letters. “It’s Read More…

Addressing the speciation mess: View species as models?

The abstract of a new paper, “Species as Models” by Jun Otsuka of Kyoto University (PhilSci Archive, 2018): This paper argues that biological species should be construed as abstract models, rather than biological or even tangible entities. Various (phenetic, cladistic, biological etc.) species concepts are defined as set-theoretic models of formal theories, and their logical Read More…

World’s simplest animals as different from each other as humans and mice

The world’s simplest animal is trichoplax adhaerens. It is so simple that researchers wisely decided to forego the venerable Biological Species Concept that depends on an animal’s form (tricoplax doesn’t have much of a form) and just use genetics. But when evolutionary biologist Michael Eitel sequenced the genomes of several thousand of them, he was Read More…

New goal: 66k animal genomes mapped

Earlier this month, 15 genomes were released. The Vertebrate Genomes Project aims to sequence every extant vertebrate species—there are about 66,000—and to make them of the highest possible value. … “What we thought was a ‘genome’ back [when G10K was launched] really wasn’t suitable for in-depth studies,” G10K cofounder David Haussler, a computational biologist at Read More…
