An Exploration of Different Theories of Evolution Essay -- Life Evolut

An geographic expedition of Different Theories of Evolution Where did we come from? It is a incertitude that has haunted the total history of humankindity. Thousands of years ago, our ancestors sought to conclude the movement with myths. Today, we argon let off struggling with the like questiononly now we seek to answer this mystery with science. Given various observations, it seems plausible that entirely spiritedness arose from a few very simple organisms millions of years ago. Observations of life will cram two important (though almost paradoxical) questions Why ar there so legion(predicate) several(predicate) kinds of life? And why do there shape up to be some over-riding similarities among organisms? The diversity of life is seeming in the extensive number of different species of plants and animals that exist on earth. By the mid twentieth Century, there was an estimated 1 to 2 million different types of organisms. (12) Now, however, the number is te ar down higher and is expected to continue to climb as more discoveries atomic number 18 made. That there are prevailing similarities among organisms is equally apparent. (13) on the whole organisms use the same biochemical mechanisms to function. For example, all organisms use DNA and many proteins that make up cells and serve as enzymes are the same crosswise species. (12) Also, organisms that are so-called to be about related tend to role certain characteristics. For example, the mug up in a whales front flipper are arranged in much the same way as the bone in human beings arms and both whales and humans are mammals and and so more closely related than say humans and squid.
