You have a supplier spreadsheet with a category column that reads Animals > Dogs > Food, and you want Drupal to end up with a real taxonomy tree: Animals, with a child Dogs,...
The first experiment that Christoph Adami discusses is one where scientists transported lizards from one island to another. Source
Why do some groups of organisms contain thousands of species while others have only a handful? Evolutionary biologists have spent decades trying to answer this question using mathe...
CT scans and DNA revealed that Australia’s rare sea muppets only look like seahorses and actually belong to a separate evolutionary lineage. A tiny fish from southern Australia cou...
A human, an octopus, and a coral could hardly look more different—yet deep inside their cells, their chromosomes still carry recognizable pieces of a genome inherited from an anima...
In the end, Christoph Adami’s method has not shown anything about the entropy or information content of ancestral sequences. Source
Fossils anchor root evolution to the tree of life
What Adami has actually done is taken a prediction that has nothing to do with evolution and attribute it to evolutionary theory. Source
Growing evidence that early human relatives do not fit neatly into traditional categories is prompting a proposal to expand the genus Homo. The human family tree is becoming harder...

To make sense of some characteristics that species exhibit from birth, you have to turn to an old discredited theory known as Lamarckism.
"According to evolution, biology should be a level below human technology because evolution is constrained." Source
Solanaceae species diversification began in the Late Cretaceous -- when dinosaurs ruled the Earth
Recent advances in our understanding of human evolution challenge the way we currently name and classify our ancestors, according to new research from Monash University. The study,...
Nobody looks at a bear and thinks, “If it only had a long tail, it would be more bear-like.” Source
The enzymes found in modern organisms are complex proteins, often with multiple folded substructures and specialized catalytic sites. Proteins are encoded by genes. Tracing the his...
Far beneath the surface of the ocean lies the largest and least explored habitat on Earth. The deep sea is cold, dark, highly pressurized—and home to a huge amount of undiscovered...
It’s a familiar concept: the long, slow march from mud to mind meant that only toward the upper tier would we find such developments as cognition. Source
Evolution is a fact of life. So much so that even the theory of evolution is evolving. Lately, a centuries-old discredited idea has been making a strong comeback. It helps us expla...
The formation of complex terrestrial ecosystems was a significant innovation in the evolutionary history of life on Earth. This event signified the expansion of life beyond marine...
Scientists believed there were only two species of hornerid bryozoans in Aotearoa New Zealand, but new research shows several more have been secretly evolving and thriving in the n...
