The Quaternary Period is the current period of the Cenozoic Era, which began about 2.6 million years ago and continues to the present day. It is characterized by a series of ice ages and interglacial periods, as well as the emergence and evolution of modern humans.
The Quaternary Period is divided into two epochs: the Pleistocene and the Holocene. The Pleistocene epoch, which lasted from about 2.6 million to 11,700 years ago, saw the development of large ice sheets in the northern hemisphere, leading to lower sea levels and changes in climate and vegetation. During this time, many large mammals, such as mammoths, sabre-toothed cats, and giant ground sloths, became extinct, possibly as a result of hunting by early humans or changes in climate.
The Holocene epoch, which began about 11,700 years ago and continues to the present day, is characterized by warmer and more stable climate conditions, which allowed for the development of agriculture and the growth of human populations. During this time, humans developed complex societies and civilizations, leading to significant impacts on the environment and the extinction of many species.
Today, the Quaternary Period is characterized by ongoing climate change, with global temperatures and sea levels rising as a result of human activities such as burning fossil fuels and deforestation. This is leading to significant impacts on ecosystems and the planet as a whole, and efforts are being made to mitigate these impacts and adapt to the changing climate.
