The latest edition, the fifth edition, was cowritten with Michael Morales and Eli C. Minkoff, and has been revised to incorporate recent discoveries and current developments in the field of vertebrate evolution. This new addition includes entirely new sections. Some examples of these are conodonts, primates, and dinosaurs.
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. [3]
The mechanisms of evolution focus mainly on mutation, genetic drift, gene flow, non-random mating, and natural selection. Mutation: Mutation [12] is a change in the DNA sequence inside a gene or a chromosome of an organism. Most mutations are deleterious, or neutral; i.e. they can neither harm nor benefit, but can also be beneficial sometimes.
Given the right circumstances, and enough time, evolution leads to the emergence of new species. Scientists have struggled to find a precise and all-inclusive definition of species . Ernst Mayr defined a species as a population or group of populations whose members have the potential to interbreed naturally with one another to produce viable ...
This edition was accompanied by a festschrift entitled Richard Dawkins: How a Scientist Changed the Way We Think (2006). In March 2006, a special event entitled The Selfish Gene: Thirty Years On was held at the London School of Economics. [64] In March 2011, Audible Inc published an audiobook edition narrated by Richard Dawkins and Lalla Ward.
Darwin made extensive revisions to the sixth edition of the Origin (this was the first edition in which he used the word "evolution" which had commonly been associated with embryological development, though all editions concluded with the word "evolved" [90] [91]), and added a new chapter VII, Miscellaneous objections, to address Mivart's ...
