High altitudes (> 8,000 ft or 2,500 m) provide an experiment of nature for measuring
adaptation and the physiological processes involved. Studies conducted over the past~ 25 …

Whether Andean populations are genetically adapted to high altitudes has long been of
interest. Initial studies focused on physiological changes in the O2 transport system that …

The ecoevolutionary drivers of species niche expansion or contraction are critical for
biodiversity but challenging to infer. Niche expansion may be promoted by local adaptation …

Populations residing for millennia on the high-altitude plateaus of the world started natural
experiments that we can evaluate to address questions about the processes of evolution …

Various approaches have been used to understand the origins of the functional traits that
characterize the Andean high‐altitude native. Based on the conceptual framework of …

High altitude, defined as elevations lying above 2500 m sea level, challenges human
survival and reproduction. This environment provides a natural experimental design wherein …

The tropical Andes are a global hotspot of avian diversity that is characterized by dramatic
elevational shifts in community composition and a preponderance of recently evolved …

High-altitude adaptation is a classic example of natural selection operating on the human
genome. Physiological and genetic adaptations have been documented in populations with …

Abstract Objectives The Sherpa ethnic group living at altitude in Nepal may have
experienced natural selection in response to chronic hypoxia. We have previously shown …

Biological anthropologists aim to explain the hows and whys of human biological variation
using the concepts of evolution and adaptation. High-altitude environments provide …
