Evolution in Four Dimensions: Genetic, Epigenetic, Behavioral, and Symbolic Variation in the History of Life is a book by Eva Jablonka and Marion J. Lamb about evolutionary biology. First published by the MIT Press imprint Bradford Books in 2005, the book challenges the gene-centric view of evolution for what the authors consider its excessive ...
The Variation of Animals and Plants Under Domestication is a book by Charles Darwin that was first published in January 1868. A large proportion of the book contains detailed information on the domestication of animals and plants but it also contains in Chapter XXVII a description of Darwin's theory of heredity which he called pangenesis .
J. Bruce Walsh was skeptical of Jablonka's claims in the book Epigenetic Inheritance and Evolution regarding the importance of epigenetic inheritance in evolution. [11] R. J. Berry, however, wrote that the book made a strong case for the importance of epigenetic inheritance in evolution and recommended the book for evolutionary biologist
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.
Classical genetics is often referred to as the oldest form of genetics, and began with Gregor Mendel's experiments that formulated and defined a fundamental biological concept known as Mendelian inheritance. Mendelian inheritance is the process in which genes and traits are passed from a set of parents to their offspring.
Genetic variation can be identified at many levels. Identifying genetic variation is possible from observations of phenotypic variation in either quantitative traits (traits that vary continuously and are coded for by many genes, e.g., leg length in dogs) or discrete traits (traits that fall into discrete categories and are coded for by one or a few genes, e.g., white, pink, or red petal color ...
In 1985, biologist Robert G. B. Reid authored Evolutionary Theory: The Unfinished Synthesis, which argued that the modern synthesis with its emphasis on natural selection is an incomplete picture of evolution, and emergent evolution can explain the origin of genetic variation.
The transgenerational inheritance of a stress response can contribute to the heritable plasticity of the organism, allowing it to better survive environmental stresses. It also helps add to the genetic variation of specific lineages with little variability, giving a greater chance of reproductive success .
