Human Evolution FA1302 8 December 2013 Did Climate Affect Human Evolution? Climate and environmental change has played a vital role in Earth’s history‚ and the outcome of these changes has been anything but idle in the evolution of primates. These drastic transformations in the planet’s atmosphere have been the impetus of evolution among species and has sparked interest to geologist and paleoanthropologist for years‚ resulting in a number of hypothesis that “propose that climate-driven environmental

Cannabis Effects on Human Beings In today’s society‚ there are many opinions about certain topics‚ such as illegal substances‚ that differ from one person to another. Those opinions‚ sadly‚ are shaped mostly by things that one hears or sees. However‚ fallacies have become extremely common nowadays.

How Important is Water?As we all know‚ water is essential for mankind ’s survival. However‚ people seem to believe that our water supply is endless since there is more water than land on this Earth. Water regenerates and is redistributed through evaporation‚ making it seem endlessly renewable. So why worry?Actually‚ only one percent of the world ’s water has the capability of being used by us. About ninety-seven percent is salty seawater‚ and two percent is frozen in glaciers and polar ice caps.

Enzymes are catalytic proteins that selectively speed up chemical reactions without by consumed by the reaction itself (1). Enzyme activity is significantly affected by factors such as temperature‚ substrate concentration‚ enzyme concentration and pH. Enzymes are highly specific and only catalyse one specific chemical reaction‚ speeding up the reaction by lowering the activation energy‚ the energy required to start a chemical reaction (2). At high temperatures and with various mechanical forces or

There are‚ however‚ more concrete ways to promote habitat conservation. There are several organizations in the Philippines dedicated towards the conservation of wildlife and wildlife habitats. One example is the World Wide Fund for Nature or the WWF. WWF in the Philippines has done numerous projects‚ which aim to conserve wildlife and biological richness

The Effects of Human Activity on Climate Climate is a natural activity that can be defined as the weather conditions prevailing in an area in general over a long period of time (which can include temperature‚ air pressure‚ humidity‚ precipitation‚ sunshine‚ cloudiness‚ and winds) (“Climate”). The climate has been a part of our environment long before humans came to study it‚ and really took it into consideration. Now through the many negative environmental actions created by humans through beneficial

MAN WILDLIFE CONFLICT Introduction: Human–wildlife conflict refers to the interaction between wild animals and people and the resultant negative impact on people or their resources‚ or wild animals or their habitat. It occurs when growing human populations overlap with established wildlife territory‚ creating reduction of resources or life to some people and/or wild animals. Conflict between people and animals is one of the main threats to the continued survival of many species in different parts

on Human Evolution This article explores the hypothesis that key human adaptations evolved in response to environmental instability. This idea was developed during research conducted by the Smithsonian’s Human Origins Program. Natural selection was not always a matter of ‘survival of the fittest’ but also survival of those most adaptable to changing surroundings. (Illustrations for this article coming soon.)
