to sustain cutaneous photosynthesis of vitamin D3 in low-UVB environments‚ and resulted in the evolution of pigmented skin. As hominids dispersed outside of the tropics‚ they experienced different intensities and seasonal mixtures of UVA and UVB. Extreme UVA throughout the year and two equinoctial peaks of UVB prevail within the tropics. Under these conditions‚ the primary selective pressure was to protect foliate by maintaining dark pigmentation. Photolysis of foliate and its main serum form of

bub Weather is the state of the atmosphere at a given time and place‚ with respect to variables such as temperature‚ moisture‚ wind velocity‚ and barometric pressure. Weather can be classified as day to day temperature and precipitation activity‚ where climiate is average atmospheric conditions over longer periods of time.

Intertropical Convergence Zone (ITCZ) is the area encircling the earth near the equator where winds originating in the northern and southern hemispheres come together. Consequences of the ITCZ’s movement are the "monsoon seasons" that affect areas in the tropics‚ as well as the formation of tropical storms during the local hemispheric summer (north or south of the equator). Navigators in the age of sail learned to utilize the "trade winds" that blow to the east along the edge of the ITCZ. The ITCZ was originally

Killer whales occur in more parts of the world than probably any other cetacean (see Whale). They occur in all oceans‚ both in the open ocean and close to shore‚ but are more common in the colder‚ more productive waters of both hemispheres than in the Tropics. Resident populations may cover an area of several hundred square kilometers. Transient populations often move through an area rapidly‚ swimming more than 1000 km (more than 600 mi) along a shoreline in a matter of days. Killer whales are black or
