Quaternary Period
The Quaternary Period is the most recent geologic time period, spanning from 2.6 million years ago to the present. It is characterized by the presence of modern humans and the periodic glaciations that have occurred during this time.
Key Events and Features
- Glaciations: The Quaternary Period is known for the repeated glaciations, with ice ages occurring at regular intervals.
- Extinction events: Several megafauna species went extinct during this period, possibly due to climate change and human activity.
- Human evolution: The Quaternary Period saw the emergence and evolution of modern humans, Homo sapiens.
- Climate change: The period has been marked by significant climate fluctuations, influencing the distribution of flora and fauna.
