Fungal pathogens cause more than a billion human infections every year, resulting in more than 1.6 million deaths annually. Understanding the natural history and evolutionary ecology of fungi is helping us understand how disease-relevant traits have repe
Generally, it is believed that hominids first evolved in Africa and then migrated to other areas. There were four main stages of human evolution. The first, between four and seven million years ago, consisted of the proto homininsSahelanthropus,OrrorinandArdipithecus.These humans may have been b...
The evolution of foresight: What is mental time travel, and is it unique to humans? In a dynamic world, mechanisms allowing prediction of future situations can provide a selective advantage. We suggest that memory systems differ in the deg... T Suddendorf,MC Corballis - 《Behavioral & ...
Evolution, theory in biology postulating that the various types of living things on Earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations. The theory of evolution is
Humans are standouts in their propensity to trade. More specially, the kind of trading found in humans—featuring the exchange of many different goods
Most models assume that the advantage of sex relies on the increased production of genetic variation, which can be used by natural selection. For this to occur, there must be forces that systematically diminish this variation (that is, that cause 'negative linkage disequilibrium'), such as genet...

As a result of recurrent NAHR events, more CYP21A2 haplotype variants with different allele patterns belonged to the same RCCX structure. The intraspecific evolution of RCCX CNV described here has provided a reasonable expectation for that of complex, multiallelic, tandem CNVs in humans. 展开 ...
Understanding how and why menopause has evolved is a long-standing challenge across disciplines. Females can typically maximize their reproductive success by reproducing for the whole of their adult life. In humans, however, women cease reproduction seve
