North and South America. Paul Martin of the University of Arizona and others see a subsequent and spontaneous connection between the presence of people and the vanishing of numerous species of large mammals. According to the overkill hypothesis‚ the spread of humanity correlates to the extinction of mammals at the same precise location they migrated to. The humans got to be big game hunters focusing on mammoths‚ giant bison‚ ground sloths‚ and other species of large size. They supposedly chased many

INTRODUCTION TO MAMMALS OF SOUTH ASIA Mammals are thought to have evolved from the class Reptilia particularly within the order Therapsida of the subclass Synapsida or “mammal-like reptiles” (Novak 1999). Adelobasileus cromptoni from the late Triassic of Texas about 225 million years old was said to be the earliest known mammal (Lucas and Hunt‚ 1990). However‚ with respect to several important characters‚ Adelobasileus shows an intermediate condition between cynodonts and mammals and its status

INNER FISH CHAPTER 1 1. The author and his colleagues wanted to use 375 million old rock‚ because in the 385 million year old rocks they found what look like fish. In the 365 million year old rocks they found amphibians that did not look like fish‚ so to find the change the look at the 375 million year old rock to find transition between the two. In their paleontology work in 2004 they found sedimentary rocks in Pennsylvania and on the east coast of Greenland‚ but their most successful rock was

The Platypus Platypus- a semi-aquatic mammal that lives in Eastern Australia. Together with the four species of echidna‚ it is one of the five nearly extinct species of monotremes‚ the only mammals that lay eggs instead of giving birth. A platypus is a mixture of a duck‚ beaver‚ and otter. The platypus is among nature’s most unique animals. The first scientists to examine a platypus thought somebody was playing a joke on them. The animal is best described as a mash-up of the duck (bill

1. In this paper I will argue that Singer is wrong to claim that human suffering and animal suffering should be given equal consideration. He claims that human animals and non-human animals with vertebrae experience pain and suffering in the same way. (41) 2. In “Animal Liberation”‚ Peter Singer argues that human suffering and animal suffering should be given equal consideration. He believes that a lot of our modern practices are speciesist‚ and that they hold our best interest above all else. The

Killer whales in captivity should be let back into the wild‚ because the whales have echolocation‚ they are causing harm to the humans taking care of them‚ and they are spacing issues at the capturing centers. These are just some of the important reasons why killer whales in captivity should be released. Presently‚ echolocation is how orca’s find their food‚ and navigate through the ocean. The orca’s make a sound and the sounds are reflected of off different objects in the ocean‚ then the orca will
