Benjamin Lewin is a molecular biologist who founded the journal Cell [1] and authored the textbook Genes. [2] He is credited with building Cell into a recognized journal of cellular biology in a short period of time to rival Nature and Science .
The Baldwin effect compared to Lamarck's theory of evolution, Darwinian evolution, and Waddington's genetic assimilation. All the theories offer explanations of how organisms respond to a changed environment with adaptive inherited change. In evolutionary biology, the Baldwin effect describes an effect of learned behaviour on evolution.
Lewin served as vice chancellor for research at University of California, Davis from 2011 until 2016. In 2016 he returned to the faculty in the University of California, Davis Department of Evolution and Ecology and the Genome Center. [11] Lewin is a member of a group biologists that propose to sequence the DNA of all life on Earth. [12]
Evolution of photosynthesis – Origin and subsequent evolution of the process by which light energy is used to synthesize sugars; Evolution of sexual reproduction; Evolutionary arms race – Competition of sets of genes, traits, or species, that develop adaptations against each other; Evolutionary capacitance – Evolutionary biology hypothesis
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]
Molecular evolution describes how inherited DNA and/or RNA change over evolutionary time, and the consequences of this for proteins and other components of cells and organisms. Molecular evolution is the basis of phylogenetic approaches to describing the tree of life. Molecular evolution overlaps with population genetics, especially on shorter ...
A large body of molecular evidence supports a variety of mechanisms for large evolutionary changes, including: genome and gene duplication, which facilitates rapid evolution by providing substantial quantities of genetic material under weak or no selective constraints; horizontal gene transfer, the process of transferring genetic material to ...
The gene-centered view of evolution is a synthesis of the theory of evolution by natural selection, the particulate inheritance theory, and the rejection of transmission of acquired characters. [ 6 ] [ 7 ] It states that those alleles whose phenotypic effects successfully promote their own propagation will be favorably selected relative to ...
