The chemistry leading to life may have begun shortly after the Big Bang, 13.8 billion years ago, during a habitable epoch when the Universe was only 10â17 million years old. Though life is confirmed only on the Earth, many think that extraterrestrial life is not only plausible, but probable or inevitable.he chemistry leading to life may have begun shortly after the Big Bang, 13.8 billion years ago, during a habitable epoch when the Universe was only 10â17 million years old.

Anatomy is the field of science concerned with the study of the physical structures of an organisms. It's divided into several branches, including histology, embryology, gross anatomy, zootomy, phytotomy, human anatomy, and comparative anatomy.
Physiology is the study of function and is closely related to anatomy which is the study of form and structure. Due to the frequent connection between form and function, physiology and anatomy are intrinsically linked and are studied in tandem as part of a medical curriculum.hysiology is the study of function and is closely related to anatomy which is the study of form and structure.
