New Modeling Tool Has Implications for Better Understanding of Disease Remember domain, kingdom, phylum, class, order, family, genus, species and Darwin’s tree of life metaphor we learned about in high school biology? That way of describing living-things lineages is just science’s best guess about
There are over 500,000 plant species in the world today. They all evolved from a common ancestor. How this leap in biodiversity happened is still unclear. Researchers now present the results of a unique project on the evolution of plants. Using genetic data from 1,147 species the team created the most comprehensive evolutionary tree for green plants to date.
Researchers analyzed the genomes of 20 butterfly species and found evidence that many butterflies — including distantly related species — have a surprisingly high amount of gene flow between them. The findings challenge conventional views about species, and indicate that hybridization may be a key process in the emergence of biological diversity.
No, but seriously, if “‘species’ are simply not what we thought they were,” as the researchers’ media release reads, all those carefully thought-out explanations of the neo-Darwinian origin of various butterfly traits must compete with “a complete morass of inter-connectedness.” Darwinism is dying
