Final answer:
The current era is the Cenozoic Era, known as the age of mammals, which began around 65 million years ago after the dinosaurs' extinction and includes the rise of human beings.
Step-by-step explanation:
The era in which we currently live is the Cenozoic Era, an epoch known for being the age of mammals. This era began about 65 million years ago and continues to this day. It represents the time after the mass extinction that eliminated the dinosaurs, which allowed mammals to flourish and become the dominant life forms on Earth. It is also referred to as the era of "modern life" and includes the rise of humans. The Phanerozoic is the current geologic eon, which began approximately 541 million years ago with the Cambrian Period and encompasses both the Cenozoic Era and other prior eras such as the Paleozoic and the Mesozoic. The Paleozoic is denoted as the era of "old life," while the Mesozoic is most well-known as the age of dinosaurs. The remarkable diversity of life and the evolution of ecosystems during the Cenozoic Era is an important part of our planet's history.
