Brian Hall traces the roots of evolutionary developmental biology in his 2012 paper on its past present and future. He begins with Darwinian evolution and Mendel's genetics, noting the tendency of the followers of both men in the early 20th century to follow separate paths and to set aside and ignore apparently inexplicable problems.

At the same time inflammation and increased production of pro-inflammatory cytokines may cause GH resistance and a decrease in circulating IGF-1 and IGFBP-3 which in turn reduces endochondrial ossification and growth. [25] [29] However, the EGP appears to conserve much growth capacity to allow for catch-up growth. [30]
Common traits which may be linked to genetic patterns are earlobe attachment, hair color, and hair growth patterns. [10] In terms of evolution, genetic mutations are the origins of differences in alleles between individuals. However, mutations may also occur within a person's life-time and be passed down from parent to offspring.
In modern times, exponential knowledge progressions therefore change at an ever-increasing rate. Depending on the progression, this tends to lead toward explosive growth at some point. A simple exponential curve that represents this accelerating change phenomenon could be modeled by a doubling function.
Irruptive growth is a growth pattern over time, defined by a sudden rapid growth in the population of an organism. Irruptive growth is studied in population ecology. [1] Population cycles often display irruptive growth, but with a predictable pattern of subsequent decline. [2] It is a phenomenon typically associated with r-strategists.
Among the earliest biological rules in modern times are those of Karl Ernst von Baer (from 1828 onwards) on embryonic development (see von Baer's laws), [4] and of Constantin Wilhelm Lambert Gloger on animal pigmentation, in 1833 (see Gloger's rule). [5] There is some scepticism among biogeographers about the usefulness of general rules.
Sclerochronology focuses primarily upon growth patterns reflecting annual, monthly, fortnightly, tidal, daily, and sub-daily (ultradian) increments of time. The regular time increments are controlled by biological clocks, which, in turn, are caused by environmental and astronomical pacemakers. Familiar examples include:
