In which era, period, and epoch do we now live?

We currently live in the Cenozoic Era, which is the most recent of the geological time scale. More specifically, we are in the Quaternary Period and the Holocene Epoch.

1. The Cenozoic Era began approximately 66 million years ago and is characterized by the dominance of mammals and birds, as well as significant developments in plant life.

2. The Quaternary Period started around 2.58 million years ago and is marked by repeated glacial cycles and significant climatic changes that have shaped the current landscape.

3. The Holocene Epoch began approximately 11,700 years ago, following the last Ice Age, and it covers the development of human civilization. This epoch still includes current climatic conditions and ecology changes directly influenced by human activity.

Thus, to summarize, we are in the Cenozoic Era, Quaternary Period, and Holocene Epoch.
