Hello and welcome to day 4 of BEDA!
So every Wednesday in BEDA we are going from Birth to life to death as humans (Human 101 if you will) but to start off the series we’re going to try and break human evolution down into simple stages.
Human evolution is basically the process that took us from being apelike creatures to the humans we see today. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years. The process of evolution involves a series of natural changes that cause species to arise, adapt to the environment, and become extinct. All species or organisms have originated through the process of biological evolution.
One of the key features of humans evolving include bipedalism which is a fancy word for walking on two legs. This is unlike the apes that use all four limbs to get around. It is not truly known what first caused early humans to get up and walk like this but there are a few theories. These theories include that humans that walked on two feet could gather more food and were therefore more successful, others have suggested that this method of movement allowed early humans to use tools more successfully. However the truth is simply not known.
Other traits include the ability for humans to use tools, a large and complex brain and the ability to use language.
