Over time‚ many theories have been developed concerning the way evolution was originated. One of these main theories was that Multicellular organisms originated slowly over the last billion years from unicellular organisms. Another main theory is that Multicellular organisms originated abruptly during the Cambrian (around 500 million years ago) explosion from unicellular organisms. While these two theories are very different from one another‚ many people support each of these ideas. However‚ I am

Evolution of Microprocessor It is interesting to note that the microprocessor had existed for only 10 years prior to the creation of the PC! Intel invented the microprocessor in 1971; the PC was created by IBM in 1981. Now more than 20 years later‚ we are still using systems based more or less on the design of that first PC. The processors powering our PCs today are still backward compatible in many ways with the 8088 that IBM selected for the first PC in 1981. November 15‚ 2001 marked the 30th anniversary

Human Evolution is just a theory. Hominids began to come to life about four to five million years ago and only one will adapt to become us. Many species had to adapt to their environment or die off. The result of changes in the environment made us today. Australopithecus aferensis are one of the first hominids‚ also known as the Australopith. The Australopith had a reason why they had to stand up on two legs. Eight million years ago‚ Africa was covered with tropical rain forests. Suddenly‚ tectonic

Evolution of Letters Nearly all modern alphabets are descended from an alphabet invented 4000 years ago‚ probably by a group of people related to the ancient Hebrews‚ Phoenicians‚ and Canaanites‚ living in what is now the Sinai desert. They got the idea from the Egyptians‚ but used their own simplified pictures to represented consonant sounds. The Phoenicians and others of the region simplified the pictures further and often rotated them‚ but if you use your imagination‚ you can still make out

Keeping through the ages and evolved into the clocks we have today. This paper intends to study the evolution of clocks‚ In terms of mechanism‚ design and the social and functional factors which led to improvements in each stage of this evolution.

that’s changed; It’s all living things. This change over time or ‘development’ is called evolution. Evolution is the change of (heritable) traits in different organisms over time. If you’re thinking apes becoming humans you’re already wrong. There’s even evidence of evolution like fossils‚ DNA samples‚ similarities in bone structure‚ and even vestigial organs. The purpose of this lab is to see how evolution works and whether it is a reliable theory. Hypothesis: If there are 11 skulls that all have

THE EVOLUTION OF NURSING Nursing is a profession that can be recalled and accounted for since prehistoric times to now it has since come a long way.

Evolution of Sciuridae Squirrels have various adaptations that have helped them through generations to become the successful organism they are today. Squirrels have adaptations that can help them in many ways for various reasons. One of these adaptations is the anatomy of their hind legs‚ and with this adaptation they are able to rotate their hind feet which allows them to go down a tree head first. Over time this species has also developed a high sense of smell‚ and during the winter time this
