Quaternary life refers to the biological and ecological developments that have occurred during the Quaternary period, which began approximately 2.58 million years ago and continues to the present day. The Quaternary period is divided into two epochs: the Pleistocene and the Holocene (the latter of which encompasses the present time). During the Quaternary period, significant geological and climatic changes occurred, leading to major shifts in ecosystems and the evolution of various species.
