Denisovans, a group of now extinct humans who lived in Eastern Eurasia in the Middle and
Late Pleistocene, were first identified from DNA sequences just over a decade ago. Only ten …

The sequencing of ancient DNA from archaic humans—Neanderthals and Denisovans—has
revealed that modern and archaic humans interbred at least twice during the Pleistocene …

Neanderthals and modern humans interbred at least twice in the past 100,000 years. While
there is evidence that most introgressed DNA segments from Neanderthals to modern …

Recent studies suggest that admixture with archaic hominins played an important role in
facilitating biological adaptations to new environments. For example, interbreeding with …

During human evolution, the knee adapted to the biomechanical demands of bipedalism by
altering chondrocyte developmental programs. This adaptive process was likely not without …

With the rise of affordable next-generation sequencing technology, introgression—or the
exchange of genetic materials between taxa—has become widely perceived to be a …

During the late Pleistocene, isolated lineages of hominins exchanged genes thus
influencing genomic variation in humans in both the past and present. However, the …

Humans have undergone large migrations over the past hundreds to thousands of years,
exposing ourselves to new environments and selective pressures. Yet, evidence of ongoing …

Recent studies of cosmopolitan Drosophila populations have found hundreds to thousands
of genetic loci with seasonally fluctuating allele frequencies, bringing temporally fluctuating …

The evolution of mankind has constantly been influenced by the pathogens encountered.
The various populations of modern humans that ventured out of Africa adapted to different …
