Several billion years pass and life continues to evolve. At lease five times in the history of life on earth mass extinction event s have occurred. These events are thought to be caused by a meteor or asteroid impacts and or massive large scale volcanic activity. Currently life on earth is experiencing a mass extinction event. This event is being caused by the impact of humans on life on Earth.
Humans are relatively recent arrivals on Earth.
Modern humans are currently thought to have appeared on in Africa around 135,000 years ago. Only about 10,000 years ago did humans began to domesticate plants and animals. About 4,000 years ago human cultural evolution had reached the level where methods of agricultural productivity became efficient enough to enable large cities to come into existence. It is not clear as to when humans first entered into what we now call Florida. We have strong evidence that humans were present in Florida 10,000 years ago.
