The brain: For example, Broca's area, a small section of the human brain, has a critical role in linguistic capability. Hormones: Chemicals used to communicate among cells of an individual organism. Testosterone, for instance, stimulates aggressive behaviour in a number of species.
The center's research facilities are designed to enhance the health, reproduction, and reintroduction efforts of endangered species and to collect information about the general biology of raptors. The science is focused on understanding how diet, aging and environment affect the health, growth, reproduction and lifespan of the birds.
The peregrine is a highly successful example of urban wildlife in much of its range, taking advantage of tall buildings as nest sites and an abundance of prey such as pigeons and ducks. Both the English and scientific names of this species mean "wandering falcon", referring to the migratory habits of many northern populations.
Assuming a genetic distance of 2% in hierofalcons [17] corresponds to a divergence roughly 200,000–130,000 years ago, [18] the 0.6–0.7% genetic distance in the peregrine falcon-Barbary falcon ("peregrinoid") complex [16] suggests its current taxa evolved in the Late Pleistocene some 100,000 years ago or less, but before the Upper Paleolithic.
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
Analysis Utility Branch Dose–response curves: Graph that shows the magnitude of the response of an organism, as a function of exposure (or doses) to a stimulus or stressor (usually a chemical) after a certain exposure time [2]

The shaheen falcon (Falco peregrinus peregrinator) is a non-migratory subspecies of the peregrine falcon found in southern Asia from India and Sri Lanka east to southeastern China. [2] [3] It has also been described as a migratory subspecies. [4] Other common names for the subspecies include the black shaheen. [5]
