"Neoproterozoic" Natural Recordings by Native Speakers
The term "Neoproterozoic" refers to the last phase of the Proterozoic eon, which is the time period extending from approximately 1,000 to 541 million years ago. During this era, the Earth's oceans were largely devoid of oxygen, and life was largely confined to single-celled organisms. The Neoproterozoic era is often referred to as the "snowball Earth" era because of widespread glacial coverage and extreme cold temperatures.
Neoplastic refers to a new and abnormal growth of cells, typically referring to cancerous tumors or abnormal tissue growths. In medicine, the term neoplastic is often used to describe the development and progression of cancer, particularly in the context of histopathology, the study of the microscopic structure of tissues and cells.
