Octopus, Squid Genome Assemblies Reveal Hallmarks of Cephalopod Evolution
Researchers detected genome shuffling, gene expansions, and RNA editing changes in the cephalopod lineage using genome assemblies for three representatives.
Comprehensive Genealogy Spanning Modern, Ancient Humans Emerges from Large-Scale Genomic Analysis
Using a non-parametric tree-recording approach, researchers established a "genealogy of everyone" that is expected to inform human evolutionary studies.
HIV Sequencing Study in Netherlands Uncovers Virulent Variant Mutations, History
Along with analyses focused on de novo mutations contributing to virulence and transmissibility, researchers traced the HIV-1 VB variant back to at least the early 1990s.
Fast-Evolving Human Genome Sequences Found to Have Brain-Related Regulatory Roles
An integrated analysis that spanned thousands of human accelerated regions suggested they harbor regulatory elements with roles in human brain development.
Sequence-Based Blood Type Analysis Suggests Neanderthals, Denisovans Arose in Africa
The researchers used recently generated genome sequences for three Neanderthals and one Denisovan to determine their blood types and examine their evolutionary history.
