The Whale’s Evolution Whales evolved from an ancestor that lived on land. That may be incredibly hard to believe‚ but we have a lot of information to lead to that conclusion. Land mammals and whales have a lot more in common than you may think. Land mammals have hair‚ a nasal opening by its snout‚ arms‚ legs‚etc‚ and DNA leading back to millions of years. Whales also have similar qualities to those of the land mammals. Whales weren’t always the whales we know today because long ago

have named the new species Ramadapis sahnii and claim that it existed 11 to 14 million years ago‚ and is a member of the early primate family Sivaladapidae. Analysis of the jawbone shows that the species consumed leaves and was approximately the same size as a house cat‚ or to a modern day lemur. This discovery is important to the scientific community as with this discovery more information surrounding the evolutionary history of primates can be gathered and analysed. This new species will also help

SUMMARY ON EVOLUTION OF MAN. Science tells us that the earth and all other planets were made out of rings of hot gases revolving around the sun. Cooling and condensing over a period of billions of years formed the solid earth we now live on. Most of the earth was covered by water and the first form of life began in the form of single-celled bacteria. From the bacteria‚ animal life then evolved through a series of life forms up until the present day animals such as fish‚ reptiles‚ birds and beasts

With the rise of chiefdoms and states‚ this tendency became institutionalized‚ war was adopted as an instrument of policy of some of the new societies‚ and those that employed it best became - tragically - the most successful. The evolution of warfare was an autocatalytic reaction that could not be halted by any people‚ because to attempt to reverse the process unilaterally was to fall victim. -E.O.

Evolution of human intelligence The evolution of human intelligence refers to a set of theories that attempt to explain how human intelligence has evolved. These theories are closely tied to the evolution of the human brain and to the emergence of human language. The timeline of human evolution spans approximately 7 million years‚[citation needed] from the separation of the Pan genus until the emergence of behavioral modernity by 50‚000 years ago. The first 3 million years of this timeline

believe evolution is from a monkey turning into guy after thousands of years. But there is more to it than that. People all over the world have found evidence explaining the origin of man and other species. But some believe in a book called the Bible‚ the holy book for Christianity. They believe that God created everything out of thin air and made everything in “7” days. But I believe that Creationism is wrong and that evolution is the science behind the origin of man. Evolution was first

Charles Darwin and the Theory of Evolution Charles Darwin is widely known as the father of evolutionary biology. It is believed that no one has influenced our knowledge of life on Earth as much as he has. His theory of evolution by natural selection‚ which has unified the theories of the life sciences‚ explained where all the diverse living things came from and how they have been able to adapt to their specific environments. His theory reconciled a wide range of evidence to make sense of the

Charles Darwin in his book‚ On the Origin of Species‚ presents us with a theory of natural selection. This theory is his attempt at an explanation on how the world and its species came to be the way that we know them now. Darwin writes on how through a process of millions of years‚ through the effects of man and the effects of nature‚ species have had a trial and error experiment ongoing. It is through these trials that the natural world has developed beneficial anomalies that at times seem too

David Kennedy Evolution Group 4 9/22/13 Lab 1: Insect Diversity and Evolution Introduction: Insects dominate the Earth with vast diversity and number of species. They are arthropods that have articulate appendages‚ a hard exoskeleton‚ compound eyes‚ and an open circulatory system with a dorsal heart. Insects have large populations in many habitats‚ even urban environments such as Chicago. Insects are close relatives to Myriapoda‚ Chelicerata‚ and Crusacea organisms (Hoffmann 63). They are incredibly

In the recent years there has been a focus on hurricanes because they have gradually gotten stronger in the past years. Scientists became more alarmed during the latest hurricane seasons because they believe they have seen the effects of the global temperatures on hurricanes. In recent years hurricanes ravaged the earth breaking records all around the world. Japan broke its previous record of 6 typhoons with 10 in 2004(Trenberth 2005). Before the 2005 hurricane season there had never been record
