The article was the first announcement of the Darwin–Wallace theory of evolution by natural selection; and appeared in print on 20 August 1858. The presentation of the papers spurred Darwin to write a condensed "abstract" of his "big book", Natural Selection.
Professor of biology Jerry Coyne sums up biological evolution succinctly: [3]. Life on Earth evolved gradually beginning with one primitive species – perhaps a self-replicating molecule – that lived more than 3.5 billion years ago; it then branched out over time, throwing off many new and diverse species; and the mechanism for most (but not all) of evolutionary change is natural selection.
Neutral theory – Theory of evolution by changes at the molecular level; Shifting balance theory – One version of the theory of evolution; Price equation – Description of how a trait or gene changes in frequency over time; Coefficient of relationship – Measure of biological relationship between individuals
Darwin's finches. Evolutionary biology is the subfield of biology that studies the evolutionary processes such as natural selection, common descent, and speciation that produced the diversity of life on Earth.
As the most celebrated argument in evolutionary biology, (Edwards, 1998, pp. 564–569) Fisher's principle is a staple of popular science books on evolution. For example, see: Gould, Stephen Jay (2002). The Structure of Evolutionary Theory. pp. 648– 649, 678, 692. Dawkins, Richard; Wong, Yan (2004). "The Seal's Tale".
The first is a historical study of classical evolutionary thought, drawing extensively upon primary documents; the second is a constructive critique of the modern synthesis, and presents a case for an interpretation of biological evolution based largely on hierarchical selection, and the theory of punctuated equilibrium (developed by Niles ...
Universal Darwinism, also known as generalized Darwinism, universal selection theory, [1] or Darwinian metaphysics, [2] [3] [4] is a variety of approaches that extend the theory of Darwinism beyond its original domain of biological evolution on Earth.
[3] [4] [5] George Romanes dubbed this view as "Wallaceism", noting that in contrast to Darwin, this position was advocating a "pure theory of natural selection to the exclusion of any supplementary theory." [6] [7] The book is seen as laying the foundation for the neo-Darwinian theory of evolution. [6] [8]
