Speciation is a continuous process during which genetic changes gradually accumulate in
the genomes of diverging species. Recent studies have documented highly heterogeneous …

The global population is currently undergoing an upward shift in its age structure due to
decreasing fertility rates and increasing life expectancy. As a result, clinicians worldwide will be …

The transition from ‘well-marked varieties’ of a single species into ‘well-defined species’—especially
in the absence of geographic barriers to gene flow (sympatric speciation)—has …

Purpose Although surgery is used increasingly as a strategy to complement treatment with
radiation and chemotherapy in patients with metastatic epidural spinal cord compression (…

Due to a worldwide increase of cancer incidence and a longer life expectancy of patients
with metastatic cancer, a rise in the incidence of symptomatic vertebral metastases has been …

The great apes are the closest living relatives of humans. Chimpanzees and bonobos group
together with humans, while gorillas and orangutans are more divergent from humans. Here…

The typically repetitive nature of the sex-limited chromosome means that it is often excluded
from or poorly covered in genome assemblies, hindering studies of evolutionary and …

Six extant species of non-human great apes are currently recognized: Sumatran and Bornean
orangutans, eastern and western gorillas, and chimpanzees and bonobos [1]. However, …

Background Several studies suggested great ape cultures, arguing that human cumulative
culture presumably evolved from such a foundation. These focused on conspicuous …

The Southeast Asian Sunda archipelago harbors a rich biodiversity with a substantial
proportion of endemic species. The evolutionary history of these species has been drastically …
