Our journey to become modern humans is a story of adaptation. Humans’ uniqueness from other species is a result of their complex thinking, body structure, migration patterns, sense of community and fighting for survival. All of these traits have evolved over millions of years and led humans to be special and unique. This uniqueness would not be there if one of the traits was to be removed, and there is a strong bond between them.
Humans’ complex thinking, including language skills, bigger size of brains helped them for a better understanding of the environment. Humans’ ability to analyze their surroundings at a deeper level is due to the development of brain’s frontal cortex, which first appeared during the time of genus homo. With the development of human’s intelligence the age of maturity started to increase, which gives more time to children for understanding. As the fossil evidences show, the first human ancestors had more small skulls and brains, and because of that they couldn’t analyze things the way that modern humans are doing.
The body structure of a modern human isn’t the same was as it is being seen today. The fossils show that the first humans were much smaller, and also that they couldn’t walk in two legs at first. Donald Johansson found Lucy in 1974, and as the fossil record shows, she was one of the first bipedals, which walked on two feet. Losing body hair through time also helped humans to a better metabolism and not sweating. The body structure change through time and it had a lot of effect in humans’ evolution.
Around six million years ago, the first human ancestors started to move to different places, because of food and survival. The challenges that they faced through time also had its effects in evolution. Climate change and nature has shaped the humans in different ways and different races. Humans made their own way of survival that made…
