Geologic time is a concept that is not well understood to the general public. Ask a random person to tell you how old, geologically speaking, the earth is, and the answer ranges from a few thousand to a few million, sometimes some people guess a few billion. According to zircons, a small mineral crystal, the earth is around 4.5 Ga old. Ga stands for giga annum, or a thousand thousand, or billion. These small minerals are very resistant to weathering and the oldest of these found on earth date to about the above mentioned time. The geological time scale is basically a time scale that breaks up the earth's history, as found in rock records. The time scale is broken up into the followin...
Ecology: CONCEPT OF BIODIVERSITY
 We all know biodiversity is important for a healthy nature and all, but how exactly is biodiversity defined and what exactly are the consequences of a loss in biodiversity? These are questions that 
"We do not earn the earth from our ancestors, we borrowed it from our children" The word Biodiversity comes from a contraction of biological diversity. Biodiversity refers to the degree of variation of species or the variety of life i.e different plants, animals and microorganisms, their genes and the ecosystem in its original concept, it relates to the number of different species on an area of a certain size. Biodiversity is often used as a measure of the state/health of biological systems. It varies greatly with ecosystem and climate. The humid tropics have the greater biodiversity and biodiversity decreases towards the north and South as temperature decreases. Biodiversity has evol...
History: History of Medicine: medicine of the extinct archaic cultures. Medicine in Mesopotamia
It is great to see how some ancient cultures had quite advanced medical techniques and habits that often went down together with the society. Here
