DNA from bone fragments reveals lost populations of bovines in the cold caves of Central Asia.

Modern humans evolved from an 80-20 mixture of two deep streams
Genome models are converging on a scenario in which two stem lineages separated 1.5 million years ago, and merged together 300,000 years ago.

How Neanderthal ancestry affects growth and muscle
Study of a Neanderthal-derived haplotype of GHR show effects on height and lean body mass

How many Denisovan ancestors?
New studies magnify the observation that three groups of Denisovans may have contributed to many living people's genomes, but I find some unanswered…

The ancient mixture in cave lion genomes
Introgression is widespread among lineages of big cats. Our ancestors encountered one of the biggest products.

Matrilineal networks may be the key to understanding Neanderthal mixture
A new study focusing on the X chromosome finds repeated maternal dispersal bias in Neanderthal and modern evolution.

Tracing the wave of Neanderthal-modern interactions
A rapid expansion of modern people ran into Neanderthals and mixed with them nearly to the ends of their range.

A shorter, sharper Out-of-Africa story is emerging
A new study of genomic ancestry in Papua New Guinea supports a short timeline for the dispersal of modern people

The gene from Denisovan to Neanderthal to modern mucus
A “genetic sandwich” reveals how a block of DNA entered several populations successively and was affected by natural selection.

Denisovan HLA and its role in immunity
Today's people have inherited several immune alleles from archaic people. Understanding what difference they made is a continuing challenge.

The humanity of a new Denisovan
Identification of the Harbin skull by mtDNA and proteins and what it means to be Homo sapiens.

Lactase and the Neandertals
New research shows that a common gene variant that may explain some lactase persistence in East Asia is introgressed from Neandertals.
