Biological determinism, also known as genetic determinism, [1] is the belief that human behaviour is directly controlled by an individual's genes or some component of their physiology, generally at the expense of the role of the environment, whether in embryonic development or in learning. [2]
A mathematical example of "survival of the fittest" is given by Haldane in his paper "The Cost of Natural Selection". [61] Haldane called this process "substitution" or more commonly in biology, this is called "fixation". This is correctly described by the differential survival and reproduction of individuals due to differences in phenotype.
In Osmia rufa, for example, the female is larger/broader than males, with males being 8–10 mm in size and females being 10–12 mm in size. [29] In the hackberry emperor females are similarly larger than males. [30] The reason for the sexual dimorphism is due to provision size mass, in which females consume more pollen than males. [31]
In biology, determination is the process of matching a specimen or sample of an organism to a known taxon, for example identifying a plant as belonging to a particular species. Expert taxonomists may perform this task, but structures created by taxonomists are sometimes used by non-specialists.
Speciation is the evolutionary process by which populations evolve to become distinct species.The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages.
This study was an example of a natural experiment, called a case-crossover experiment, where the exposure is removed for a time and then returned. The study also noted its own weaknesses which potentially suggest that the inability to control variables in natural experiments can impede investigators from drawing firm conclusions.' [ 12 ]
The pygmy mammoth is an example of insular dwarfism, a case of Foster's rule, its unusually small body size an adaptation to the limited resources of its island home. A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms.
A secular example to try to illustrate predeterminism is that a fetus's future physical, emotional, and other personal characteristics as a matured human being may be considered "predetermined" by heredity, i.e. derived from a chain of events going back long before their eventual birth.
