For Evolution

In an opinion piece at the Guardian, the National History Museum's Michael Dixon says the removal of Darwin and evolution from school curriculum is worrisome.

Brown bear.

By sequencing four ancient cave bears and comparing them to other bear species, researchers retraced historical admixture of cave bears and brown bears.

Plasmodium vivax parasites that infect humans have highly similar genomes to parasites that infect apes, a finding with possible disease-eradication consequences.

The system, called EvolvR, can continuously diversify all nucleotides within a tunable window at user-defined loci using CRISPR-guided nickases.

Velociraptor mongoliensis

Using bioinformatic and molecular cytogenetic approaches, researchers retraced ancestral "diapsid" reptile genome patterns from extant bird and reptile genomes.

A phylogenetic analysis of green-blooded lizards find the trait likely arose more than once, Reuters reports.

A multi-region analysis of colorectal cancers suggests samples from opposite sides of a tumor can help trace early, invasiveness-related tumor characteristics.

Sequencing has helped clarify the baleen whale family tree, though the researchers tell the New York Times it's more of a phylogenetic network.

Using haplotype profiling, phylogenetics, and other analyses, researchers retraced sickle allele emergence to a single event occurring roughly 7,300 years ago.
