What does metazoic mean?
The metazoic era is the current geologic era, which began approximately 541 million years ago and continues to the present day. It is characterized by the dominance of multicellular animals, also known as metazoa. The metazoic era has seen the evolution of complex life forms, from simple multicellular organisms to highly specialized species. The term 'metazoic' is used in geology and biology to refer to this era, and is often used in academic and scientific contexts. The metazoic era is often divided into three sub-eras: the Paleozoic, Mesozoic, and Cenozoic. This era has been marked by significant changes in the Earth's climate, geography, and life forms. The metazoic era is a time of great diversity and complexity, and continues to shape the world we live in today.

Etymology of metazoic
The term 'metazoic' comes from the Greek words 'meta' meaning 'beyond' and 'zoic' meaning 'animal'. It was first used in the 19th century to describe the current era of multicellular life. The term is derived from the concept of the 'zoic' era, which refers to the era of animal life. The addition of 'meta' to 'zoic' indicates that this era is beyond the previous era of single-celled organisms.
