Migration Essay

Migration is an ancient adaptation that occurs when organisms move from one climate to another as part of an ancient rhythm. An adaptation is a change or the process of change by which an organism becomes better suited to its environment. Migration is the process of all or a part of any animal population moving from one location to another. Another important part of Migration is that it ends, the organisms involved will return or move on to the next phase or location in their migration. Migration helps adaptation along by allowing organisms to find food in new hunting/grazing areas, a better environment with more appropriate habitat, or breeding grounds that allow a larger number of animals come together making it easier to find a mate.

Others go from breeding ground to feeding area and the last kind go from breeding areas to hibernation sites. Migration has another form, called emigration. Emigration is usually when an organism makes a change in location, and doesn't usually go back to the original aria afterwards. Humans do this more often than animals do, its the opposite of migration in that respect. Range expansion is another form of Migration, and it occurs when a species grows large or spreads out making their habitat much

Most organisms do it, even homo sapiens partake in it, starting with the fertile crescent and still do it today. It's necessary for organisms to do this, without it many would have become extinct due to weather, predators, and overpopulation, amongst many other things. Because it has gone on for so long now, it has become more like instinct for some of the animals to find their way. However, many still use the sun, stars, landmarks, and the earth’s magnetism to guide them. Organisms usually migrate to avoid inhospitable weather conditions, to find more food sources, and to have safer breeding grounds. Migrators will do whatever it takes to get to where they need to go. Literally traveling to one end of the world to another, shutting down harbors and roads because of the sheer numbers in their groups, and taking up to four generations to reach their destination are only a few examples of what there willing to
