Evolution

Several theories explain the existence of man. However, archeologists have come up with evidence that supports the Darwin theory that explains the evolution of man from ape. Man’s ability expended in the process and pushed him to abandon the ‘ape-lifestyle’ for a more reserved and settled (Smith, 2001).

Human Characteristics that enabled them to Fully Conquer the World

Man has exhibited superiority over the rest of apes and animals through his occupation and dominance in most parts of the earth. Instincts and the necessity for survival drove man to development and evolution; a factor witnessed his gradual shift from a bush ape. By 18,000 years ago, he had established himself as powerful, beating all odds of survival (Prothero &Buell, 2007).
The first characteristic that defined man’s superiority over the rest is his level of intelligence. The high degree of competition for food and territory drove man to ideally develop mechanisms that would limit the competition for him and establish his comfort. His intelligence drove him to develop agriculture for food sustainability (Bowler, 2007). However, agriculture and the hunt for other dietary supplements were not any easier. As such, the evolving ape created tools that he would use to farm, hunt and even cook (Carmines & Stimson, 1989).
At the first instance, he developed weapons that were primarily meant for protection and hunting. However, when the competition for space intensified, man used his arms and tools to conquer new land and habitat. Gradually, he developed the ability to build homes, villages and finally towns and centers. This intelligence was derived from an ever expanding brain.
The second characteristic that coupled man in his evolution was the change in posture. Using the forelimbs for grabbing objects, there was increased ease in the creation and development of tools and the eventuality leading to machinery (Fleagle, 1989). The position enabled man to spot enemy attacks from afar and scheme a defense mechanism. Moreover, some of the activities that man engaged in like farming required agility and swiftness, something that was enabled through the upright posture (Ruse, 2011).
To date, no animals have the characteristics that man professes.

Archeological Evidence of the Arrival of Man in America

After removal of glacier from the Pacific in 15 ka, man commenced to colonize the America. Evidence at the Channel Island, points at the ability of man at that time to use boats. From the Northwest Pacific, man spread further Southwards along the Coast towards Chile. Another contingent spread Eastward along the Continental ice sheets of the Southern margin. This contingent was [possibly on the traces of the mastodons and mammoths.
The quarry-dumpsites of the Clovis in Southeastern of the U.S are resultants of durable time-depths at the locality compared to other regions. Further evidence has been drawn from the discovery of Pre-Clovis spots at Ice sheets in Canada (Bowler, 1989).

The Lifestyle of Hunters

The hunters developed tools for to enable hunting. They also used traps that made the capture of faster animals easier. At this time, man had developed fire that he used to cook his meat. To supplement the protein, the evolving man gathered roots, fruits, and leaves. Some of the accumulated food was eaten raw, but others were cooked. Through gathering, man had developed the ability to treat himself through the use of herbs (Dawkins, 2006).
The dental arrangement also changed to accommodate the feeding habit. Man at this time was healthier due to the excellent and varied diet.
Some populations, however, took long to move to the next step of evolution and abandon hunting and gathering. Many a times, this was facilitated by little competition as the tools they had enabled them to practice continued dominance over other animals that seemingly could learn the tricks (Barton, 2007).

Changes in Lifestyle

As a man evolved, his expanding brain gave him the now to build and move his habitat from caves to crude huts and finally well established and managed homesteads and villages.
Survival necessity pushed ma.............
