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 ...
After Man was at the time of its release portrayed in reviews as a book about the extinction of mankind, though Dixon has stated that mankind's end was simply an excuse to discuss evolution, humanity having very little do with the "plot" of the book. [2] Following its success, the book has been translated into a number of different languages. [5]
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 ...
A recapitulation theory of evolutionary development was proposed by Étienne Serres in 1824–26, echoing the 1808 ideas of Johann Friedrich Meckel. They argued that the embryos of 'higher' animals went through or recapitulated a series of stages, each of which resembled an animal lower down the great chain of being.
The book follows a path backwards in time through evolution and meets different groupings of organisms. In this backward chronology, the ancestors of any set of species must eventually meet at a particular moment. The last common ancestor is the one that they all share which the authors call a "concestor".
The evolution of animals with backbones is one of the greatest stories in natural history. To tell this story, David presents explosive new fossil evidence from China, a region he has long dreamt of exploring and the frontier of modern paleontological research. This episode goes through how the vertebrates evolved and came onto land.
The Future Is Wild (also referred to by the acronym FIW) [1] is a 2002 speculative evolution docufiction miniseries and an accompanying multimedia entertainment franchise. The Future Is Wild explores the ecosystems and wildlife of three future time periods: 5, 100, and 200 million years in the future, in the format of a nature documentary.
