Before Halloween turned into a candy and costume-driven commercial phenomenon, its origins span centuries and diverse global evolution.
Evolutionary developmental paleobiology examines the evolutionary aspects of the modes and trajectories of growth and development in the evolution of life – clades both extinct and extant. See also adaptive radiation, cladistics, evolutionary biology, developmental biology and phylogenetic tree.

Graves Jr. (born 1955) is an American evolutionary biologist and geneticist.He is a professor of biological science at North Carolina Agricultural and Technical State University, and a former associate dean for research at the Joint School for Nanoscience and Nanoengineering, which is jointly administered by North Carolina A & T State University and UNC Greensboro.
The idea of evolution by natural selection was proposed by Charles Darwin in 1859, but evolutionary biology, as an academic discipline in its own right, emerged during the period of the modern synthesis in the 1930s and 1940s. [8] It was not until the 1980s that many universities had departments of evolutionary biology.
Deborah Charlesworth FRS FRSE (née Maltby; born 1943) is a population geneticist from the UK, notable for her important discoveries in population genetics and evolutionary biology. [3] [4] Her most notable research is in understanding the evolution of recombination, sex chromosomes and mating system for plants. [3]

Halloween's eerie evolution into a $6 billion industry Nicole New, left, Aja Stephens and Eric Jacobsen consider costume options. Customers wait to pay for their costumes at Halloween Adventure.
These experiments address various important questions in evolutionary biology: does evolution proceed in small steps or in large leaps; is evolution reversible; how does complexity evolve? It has been shown that slight mutations in the amino acid sequence of hormone receptors determine an important change in their preferences for hormones.
