The case for epigenetic inheritance in evolution
It is commonly thought that genotype is a property assignable exclusively to the nucleic acid genome while phenotype is a property whose assignment must be distributed among entities at many or all levels of biological organization. In evolutionary biology there is a problem of hierarchy in the theory of selection due to this requirement for distributive assignment: to which level(s) is the cau...
متن کاملEpigenetic Inheritance: What News for Evolution?
Whether epigenetic variation is important in adaptive evolution has been contentious. Two recent studies in Arabidopsis thaliana significantly add to our understanding of genome-wide variation and stability of an epigenetic mark, and thus help pave the path for realistically incorporating epigenetics into evolutionary theory.
متن کاملEpigenetic variation, inheritance, and selection in plant populations.
Plant populations show phenotypic diversity, which may be caused by genetic and epigenetic variation. It has recently been shown that new epigenetic variants are generated at a higher rate than genetic variants and several studies have shown that epigenetic variation can be influenced by the environment. Although the heritability of environmentally induced epigenetic traits has gained increasin...
متن کاملEpigenetic inheritance speeds up evolution of artificial organisms
DNA is not the sole medium by which parents transmit information to their offspring. Epigenetic inheritance, in particular, is based on the partial transmission of the cellular state of the parental cell to its descendants. Although the reality of epigenetic inheritance is now firmly established, whether it has an influence on the long term evolutionary process is still subject to debate. To ad...
متن کاملEpigenetic inheritance systems contribute to the evolution of a germline
Differentiation within multicellular organisms is controlled by epigenetic markers transmitted across cell division. The process of differentiation will modify these epigenetic markers so that information that one cell type possesses can be lost in the transition to another. Many of the systems that encode these markers also exist in unicellular organisms but do not control differentiation. Thu...
