WebClines in life history traits, presumably driven by spatially varying selection, are widespread. Major latitudinal clines have been observed, for example, in Drosophila melanogaster, an ancestrally tropical insect from Africa that has colonized temperate habitats on multiple continents. Yet, how geo … Ontogeny (also ontogenesis) is the origination and development of an organism (both physical and psychological, e.g., moral development ), usually from the time of fertilization of the egg to adult. The term can also be used to refer to the study of the entirety of an organism's lifespan. Ontogeny is the developmental history of an organism within its own lifetime, …

WebLande (1982) has presented a quantitative genetic model for the evolution of ontogenetically varying traits which clearly defines the parameters required for an analysis of ontogeney and evolution: (1) the genetic variance/covariance matrix; (2) the … Weblution of ontogenies. Direct selection at any age results in a correlated response at all other life history stages. This selection al ters growth curves, or causes the evolution of ontogeny.
