Understanding past domestications is an exciting area of interdisciplinary investigation, between archaeologists and plant scientists, which may offer insights relevant to future directions in the evolution of crops under human manipulation.
Genetic and genomic approaches, often used in concert with ethnobotanical data, have been successful in illuminating the evolution of crops from wild species under domestication (Purugganan and Fuller 2009).
An in-depth analysis of the spatio-temporal evolution of crop diversity in agricultural landscapes is necessary to provide insights on how to improve the resilience of agroecosystems to climate instability and new pest pressures by increasing in situ crop diversity, while promoting a greater sustainability of agriculture.
The recurrent evolution of crop-related weeds during agricultural history raises serious economic problems and challenging scientific questions.
Evolutionary processes represent environmental adaptations over long time scales; evolution of crop genomes is not inducible within the relatively short time span of a human generation.
It is a crucial step in the evolution of crop species since humans have an important impact on their origins and changes.
Yunnan province is renowned for three kingdoms of plants, animal, and nonferrous metals, parallel evolution of crop adaptation to nonferrous metals, and anticancer foods for human being are mostly cultivated in this region.
However, management plans to hinder the evolution of crop pests are rarely designed at the landscape scale and if so, they do not consider remnant patches of wild vegetation.
Large scale population genomic analyses have the potential to provide insight into evolution of crop plants and their genomes, since the genomic regions that have been targeted by selection during crop evolution are expected to exhibit characteristic changes in levels of polymorphism [ 41].
Around the world, crop diversity is concentrated in a number of centers of origin and diversification, where evolution of crop species has occurred through millennia of interacting natural and human selection pressures, heterogeneous environments, isolation, migration, and farmer exchange (Harlan 1975).
Here, we used artificial selection to measure the rate of evolution of crop-wild hybrids compared to their wild relative under simulated ecological contexts that favored two traits found in a hybrid-derived weed: early flowering, a wild-type trait, or long leaf length, a crop-derived trait that is correlated with plant size and lifetime fecundity.
