Some things different from our ancestors:

1. Smaller bodies: Our bodies now are generally shorter, lighter, and smaller boned. There are many factors that affect body size. They have to do with genetics, environment, diet, and technology.

2. Height: There has been an increase in height over the time that humans evolved. This has to do with diet and health care as well.

3. Smaller brains: Our ancestors used to have much larger brains than ours. The average brain size for a human 100,000 years ago was 1500 cc (cubic centimeters). The average brain size today is 1350 cc (cubic centimeters).

4. Physical Diversity: In today’s times, humans show an enormous diversity in appearance. This was not the same as past humans. It is said that early members of our species lived in Africa. They had evolved physical characteristics that were similar to each other in order to survive that specific climate. Over time, genetic traits have changed due to the different climates.
