About 70% of crop genetic diversity and 30% of livestock genetic diversity has been lost. [19] The loss of genetic diversity reduces the resilience of food systems to pests, diseases, abiotic stresses, and climate change, posing a threat to food security. [20] These risks can reduce yields, therefore having an economic and social impact.
Ecological economics is an economic science that extends its methods of valuation onto nature in an effort to address the inequity between market growth and biodiversity loss.

James Clerk Maxwell developed a model to explain electric and magnetic phenomena using the aether, a model that led to what are now called Maxwell's equations and the understanding that light is an ...
In maximum parsimony, Dollo parsimony refers to a model whereby a characteristic is gained only one time and can never be regained if it is lost. [8] For example, the evolution and repeated loss of teeth in vertebrates could be well-modeled under Dollo parsimony, whereby teeth made from hydroxyapatite evolved only once at the origin of vertebrates, and were then lost multiple times, in birds ...
