Genetic variation, which is generated by mutation, recombination and gene flow, can reduce
the mean fitness of a population, both now and in the future. This 'genetic load'has been …

Although the first ancient DNA molecules were extracted more than three decades ago, the
first ancient nuclear genomes could only be characterized after high-throughput sequencing …

Domestication of horses fundamentally transformed long-range mobility and warfare.
However, modern domesticated breeds do not descend from the earliest domestic horse …

During the last glacial–interglacial cycle, Arctic biotas experienced substantial climatic
changes, yet the nature, extent and rate of their responses are not fully understood …

Despite the substantial role that chickens have played in human societies across the world,
both the geographic and temporal origins of their domestication remain controversial. To …

The domestication of animals led to a major shift in human subsistence patterns, from a
hunter–gatherer to a sedentary agricultural lifestyle, which ultimately resulted in the …

The evolutionary basis of domestication has been a longstanding question and its genetic
