Paragraph
Prehistoric ancestors have contributed greatly to humans today to become who we are now.

Prehistoric ancestors have contributed greatly to humans today because they have traditionally passed down some physical abilities. Homo erectus gradually developed what is now our language 2 million years ago so we have the ability and knowledge of communication. They needed some form of communication to help on another to survive and because of that we depend on it to help one another as well. Our ancestors like Lucy also helped us develop the ability to walk upright which makes it easier to carry objects. As well they also developed opposable thumbs so it is easier to grip and hold objects. This contributes to our ability to carry,hold, and move objects for work and leisure purposes.

Prehistoric ancestors have contributed greatly to humans today because they created tools. Homo habilis developed uni facial tools like bristle brushes and rocks to make tasks less work to do. Homo erectus however developed bi facial tools that served the same purpose. Also homo erectus introduced fire to burn, cook, and heat with. Prehistoric ancestors have contributed greatly to humans today because they taught us art. They painted for religious and leisure purposes as a hobby. They also created 3d techniques to make it more realistic. Along with carving as another art style so we could have self expression. Some art symbols were used as a communication.
Thanks to our prehistoric ancestors we are able to do the many amazing tasks we can do today.
