The Avalon explosion, named from the Precambrian faunal trace fossils discovered on the Avalon Peninsula in Newfoundland, eastern Canada, is a proposed evolutionary radiation of prehistoric animals about 575 million years ago in the Ediacaran period, with the Avalon explosion being one of three eras grouped in this time period.

Modern-day zoogeography also places a reliance on GIS to integrate a more precise understanding and predictive model of the past, current, and future population dynamics of animal species both on land and in the ocean. Through employment of GIS technology, linkages between abiotic factors of habitat such as topography, latitude, longitude ...
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 ...
While Lamarck's contributions to science include work in meteorology, botany, chemistry, geology, and paleontology, he is best known for his work in invertebrate zoology and his theoretical work on evolution. He published a seven-volume work, Histoire naturelle des animaux sans vertèbres ("Natural history of animals without backbones;" 1815 ...
The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
Canada's 15 terrestrial ecozones are further subdivided into 53 ecoprovinces, 194 ecoregions, and 1,027 ecodistricts. [13]Canada is characterized by a wide range of both meteorologic and geological regions that are divided into fifteen terrestrial and five marine ecozones, [14] such as the forests of British Columbia and Central Canada, the prairies of Western Canada, the tundra of Northern ...
Rereading the Fossil Record: The Growth of Paleobiology as an Evolutionary Discipline (University of Chicago Press; 2012) 432 pages; A history since the mid-19th century, with a focus on the "revolutionary" era of the 1970s and early 1980s and the work of Stephen Jay Gould and David Raup. Paul Tasch (1980). Paleobiology of the Invertebrates.
Humans determine which animal or plant will reproduce and which of the offspring will survive; thus, they determine which genes will be passed on to future generations. The process of artificial selection has had a significant impact on the evolution of domestic animals. For example, people have produced different types of dogs by controlled ...
