As the economy re-opens, some of the changes may be permanent, particularly in cities where housing and mass-transit have faced major downswings.
Beginning of animal evolution. [54] [55] 720–630 Ma Possible global glaciation [56] [57] which increased the atmospheric oxygen and decreased carbon dioxide, and was either caused by land plant evolution [58] or resulted in it. [59] Opinion is divided on whether it increased or decreased biodiversity or the rate of evolution. [60] [61] [62 ...
Pharmaceutical companies utilize biological evolution in their development of new products, and also use these medicines to combat evolving bacteria and viruses. [94] Because of the perceived value of evolution in applications, there have been some expressions of support for evolution on the part of corporations.
Even as America's westward expansion allowed over 400 million acres (1,600,000 km 2) of new land to be put under cultivation, between 1870 and 1910 the number of Americans involved in farming or farm labor dropped by a third. [87] New farming techniques and agricultural mechanization facilitated both processes.

European colonization of the Americas led to the rise of new cultures, civilizations and eventually states, which resulted from the fusion of Native American, European, and African traditions ...
