HUMAN EVOLUTION TIMELINE

Timeline of Human Development

• About 800,000 years ago, the fire was conntrolled by early humans.
• About 6 million years ago most early human species became bipedal.
• The Homo Habilis used to live in Eastern and Southern Africa.
• About 12,000 years ago, humans managed to control the growth and breeding of some               certain plants and animals.
• The Sahelanthropus tchadensis is the earliest  human species from the timeline.

Answer these questions:

1.      What´s been the role of climate change in the development of humans?

The climate change has occurred parallel to the development of human. In times past, one of the great events was for example: Due to widespread droughts and climate fluctuation between 90,000 and 70,000 years ago, the Homo sapiens almost becomes extinct, the fastest brain size increase in early humans occurred during the era of greatest climate fluctuation. Other example is like the Homo erectus survives habitat change in China. In conclusion the development of human occurred during  greatest climate fluctuations.

2.      In your opinion, what is the most significant milestone for the human evolution? Why?

In my opinion, the most significant milestone for the human evolution was when the early human species started to walk upright most of the time. This helped them to have a better vision for hunting.

3.      Which early human species was thought  to be  the first to use tools made from stone?

Homo habilis, this species was thought  to represent the first stone toolmaker.

4.      Who were the first human species to travel to and live in Europa? When?

ü  Homo heidelbergensis, these were the first early humans to venture into the cold latitudes of Europe about 700,000 to 200,000 years ago.

ü  Homo neanderthalensis lived Europe about 200,000-28,000 years ago.

5.      Which species survived for the longest  time? For how long?

ü  Homo erectus was the longest-lived species on our family tree, surviving more than nine times as long as our own species

ü  Homo floresiensis, this early species is the one that went extinct most recently, it coexisted with humans during the entire duration of its known time range, about 95,000-17,000 years ago.

ü  Homo sapiens were the sole surviving species left in our once diverse family tree. About 200,000 years ago to present.
