In modern terms, this transmission from parent to offspring could be considered a method of epigenetic inheritance. Scientists are now questioning the framework of the modern synthesis, as epigenetics to some extent is Lamarckist rather than Darwinian. While some evolutionary biologists have dismissed epigenetics' impact on evolution entirely ...
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 ...
Epigenetic mechanisms. In biology, epigenetics is the study of heritable traits, or a stable change of cell function, that happen without changes to the DNA sequence. [1] The Greek prefix epi-(ἐπι-"over, outside of, around") in epigenetics implies features that are "on top of" or "in addition to" the traditional (DNA sequence based) genetic mechanism of inheritance.

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 biologists. [12]
New types of inheritance, including cultural and epigenetic inheritance. [55] [56] The way that organismal development and developmental plasticity channel evolutionary pathways [57] [41] [43] and generates phenotypic novelty [48] [49] [58] How organisms modify the environments they belong to through niche construction.

Embryology theories of Ernst Haeckel, who argued for recapitulation [3] of evolutionary development in the embryo, and Karl Ernst von Baer's epigenesis. A recapitulation theory of evolutionary development was proposed by Étienne Serres in 1824–26, echoing the 1808 ideas of Johann Friedrich Meckel.
Epigenetics of human development is the study of how epigenetics (hertiable characteristics that do not involve changes in DNA sequence) effects human development. Development before birth, including gametogenesis , embryogenesis , and fetal development , is the process of body development from the gametes are formed to eventually combine into ...
It is thought that transgenerational epigenetic inheritance can enable certain populations to readily adapt to variable environments. [19] Though there are well documented cases of transgenerational epigenetic inheritance in certain populations, there are questions to whether this same form of adaptability is applicable to mammals.
