WebApr 11, 2024 · The "Modern Synthesis" paradigm of the 1930s and 1940s resulted from integrating Darwin's evolutionary theory based on natural selection with the finding of granular gene heredity. The Modern Synthesis disproved many biological myths, notably Lamarck's notion of acquired character transmission and the mixing concept of inheritance.

WebEvolution is not the same as adaptation or natural selection. Natural selection is a mechanism, or cause, of evolution. Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits. WebPopulation genetics is the study of the transmission of genetic variation through time and space. This course explores what the patterns and dynamics of genetic variation in populations can teach us about the processes that underlie evolution. Topics include the quantification of genetic variation, mutation, selection and fitness, genetic drift, …
