The earliest humans must have had and passed on knowledge about plants and animals to increase their chances of survival. This mayhave included knowledge of human and animal anatomy and aspects of animal behavior (such as migration patterns). However, the firstmajor turning point in biological knowledge came with the Neolithic Revolution about 10,000 years ago. Let’s trace the history of Biology
PREHISTORY Homo sapiens – 1.75 million B.C. origin (4.5 billion B.C.) Human speech – 50, 000 B.C. Writing – 4, 000 B.C. The age of the Earth has been determined to be 4.54 billion years old Pre history is a term used to describe a period before the recorded history. The term "prehistory" can be used to refer to all time since the beginning of theuniverse, although it is more often used in referring to the period of time since life appeared on Earth, or even more specifically to the time since human-likebeings appeared. In dividing up human prehistory, prehistorians typically use the Three age system, whereas scholars of pre-human time periods typically use the well defined Rock record and its internationally defined stratum base within the geologic time scale. The three-age system is the periodization of human prehistory into three consecutive time periods, named for their respective predominant tool-making technologies; the Stone Age, Bronze Age, and Iron Age. technology stone age bronze age iron age paleolithic mesolithic neolithic chalcolithic most advanced advent of ferrous- first use of stone - development of - primitive technological - copper age metal working metallurgy tools human technology & social development

The ancient peoples who are considered the first scientists may natural sciences such as Susruta and Zhang have thought of themselves as natural philosophers, as practitioners of a skilled Zhongjing, reflecting independent sophisticated profession (for example, physicians), or as followers of a religious tradition (for systems of natural philosophy example, temple healers).The encyclopedic works of Aristotle, Archimedes, Hippocrates, Galen, Ptolemy, Euclid, and others spread throughout the world. These works and the important commentaries on them were the wellspring Zhang of science. Hippocrates Aristotle Zhongjing known for Edwin Smith Papyrus (460 B.C.) of Egypt (384 B.C.) of China developing the established Focused on (150 A.D.) process of (16th cent.

CLASSICAL ANTIQUITY (4000 B.C. to 476 A.D.) Theophrastus Pliny the Elder (371 B.C.), Galen (129 – 199 (23 A.D.) known Aristotle’s A.D.) was arguably for his successor at the the most knowledge of Lyceum, wrote a accomplished of plants and series of books all medical nature, and was on Botany researchers of the most prolificZhuangzi, Taois antiquity.
