Adaptation in the human genome has been the main cause of the ma to co-exists with his environment. According to <u>Charles darwin </u>evolution is a phase in time that occurs at every step and this phase either through the natural selection or genetic drift occurs in the environment. As the genes that were present earlier in the organisms are now carried forward.
The westerlies are the prevailing winds that blow from the west to east in middle latitude between the 30 to 60 degrees.
These are found from the high pressure areas of the horse latitude towards to poles and sheer extra tropical cyclones.
Westerlie are strongest in the winter hemisphere, and at time when the pressure is lower over the poles, while its weakest in summers, there impact on the ocean currents when moving from west to east the western ocean current transports warm tropical water to the poles.
