Human Evolution Much Debate has surrounded the evolution of humans. However, most scientists are now agreed that modern humans, Homo sapiens, are the sole survivor of a number of human species that evolved from the common ancestor of humans and apes some six million years ago. Climatic changes forced our earliest ancestors out of the tropical forests and into open woodlands and grasslands. The challenge of these new habitats resulted in important changes, such as the ability to walk upright and an increase in brain size. Paranthropines : The Paranthropines were strongly built “ man-apes” that lived in southern and eastern Africa between three and one million years ago. They were probably descended from the Australopithecines, but were not part of the evolutionary pathway that led to modern humans. https://www.gyanguard.info/human-evolution/

The opposite of an acid is an alkali, which dissolves in water to form negatively charged ions of hydrogen and oxygen, called hydroxide ions (OH). Alkali “anti-acid”, because they tend to cancel acidity. For example, the base to control the acidity in the mouth toothpaste that will lead otherwise damage the teeth. pH scale :  The concentration of hydrogen ions in a solution is known as its pH. Scientific measuring acidity and alkalinity using a pH scale. A solution on the pH scale, low pH of 7 is an alkaline solution with acidic, and a pH greater than 7. With a pH of 7, the water at neutral. A solution’s pH can be tested with universal indicator solution or paper, which changes colour in acids and alkalis. Strong acids :  The more hydrogen ions an acid forms in water, the stronger it is, and the...

  Aboriginal Australians THE ABORIGINES settled the Australian continent more than 40,000 years ago. They lived in total isolation from the rest of the world, present by hunting and gathering.
