The Quaternary is the most recent geological period, spanning from about 2.6 million years ago to the present. It is characterized by significant climate fluctuations, including repeated glacial and interglacial cycles, leading to the formation of the current landscape and ecosystems. The Quaternary is divided into two epochs: the Pleistocene, marked by extensive ice ages and the development of modern humans, and the Holocene, which began around 11,700 years ago and encompasses the current warm period and the rise of human civilization. This period has seen the emergence and evolution of many species, including mammals, birds, and plants, as well as significant changes in sea levels and habitats.
