Species

Over the past 200,000 years humans have continued to evolve. Human evolution first began in Africa roughly 6 million years ago and it describes the long process that our ancestors went through to transform into modern day humans. One of the first original human traits that were discovered around 4 million years ago was bipedalism, which is the ability to walk on two legs. Over a long period of times humans have grown taller, we have developed smaller teeth and jaws and have developed more…

biologically, with 7 major distinct terrestrial biomes, one of which, the Cape Floral Kingdom, is endemic to the region. This biodiversity is, however, under threat due to land expansion, climate change, alien species invasion and much more (Turpie 2013). The loss of ecological settings and species demands that biodiversity should be protected by a variety of management efforts. Traditionally, the protection of biodiversity was reserved for local communities, government agencies, and welfare…

Your Inner Fish by Neil Shubin Chapter Questions Chapter 1 – Finding Your Inner Fish 1. Explain why the author and his colleagues chose to focus on 375 million year old rocks in their search for fossils. Be sure to include the types of rocks and their location during their paleontology work in 2004. The author and his colleagues chose to focus on 375 Million Years as it was a period when the transformation took place from fish to fish with limb. The fish without characteristics of…

Onaeja Lawson 10 - 06 - 2015 3rd Period Introduction Hi my name is Onaeja Lawson I am here to teach you about ecological relationships like abiotic is [non-living] and biotic is [living] stuff like that but I have more information to tell you than just abiotic and biotic is so here it goes hope you like it. What does abiotic and biotic mean? Abiotic - Physical rather than biological; not derived from living organisms. Biotic - Relating to, or resulting from living things, especially in their…

come out with ideas and proposals that challenge the human-nature dualistic thinking. They are proposing for non-human life to be acknowledged, celebrated and brought into cities, considering the importance and the various benefits of nature to our species. These city-builders recognise the importance of daily human contact with nature. Furthermore, nature and natural systems are thought to bring numerous environmental and economic values to the city and its inhabitants. Public parks, green…

pressure that would ultimately threat the survival of the herbivores as well. Thus, carnivores can provide ecological boundaries that protect weaker competitors from competitive exclusion (Miller et al., 2001). Some carnivores are regarded as keystone species due to the enormous ecological effects they impose on other…

same purpose as a swim bladder. It was recently discovered that, within this fatty organ, a vestigial lung can be found that is surrounded by small hard plates. It is believed that these plates were involved in lung volume regulation in an ancestral species, but have become rudimentary in extant coelacanths. Females are larger in size, and have higher thickness ratios and metabolic rates than males. Average mass of adult females is 82.1 kg, and average length…

supported by certain biologist’s who argue evolution favours the directional development of complex life . However, life is not a straightforward progression towards complexity. Natural selection can’t explain revolutionary change because while species produce evolutionary trends through their adaptive challenges, there are random events such as mass extinctions that dramatically alter the progress of life. Life on earth emerged from a series of fortuitous accidents. The distance of the…

Diversity and Developments Madagascar has a unique blend of customs and faiths from Southeast Asia, India, the Middle East, and Africa. It is one of the seventeen megadiverse countries in the world. Approximately 250,000 species are found in Madagascar. Over 65 percent of the species found on the island of Madagascar are not found anywhere else on earth such as elephant birds. (Dewar & Wright, 1993). Madagascar is also home to the third largest coral reef system in the world. Madagascar has an…

Honors 9/25/17 Ishmael Essay: Significance of Naming and Renaming in Ishmael The world in which all species live in is dominated by the human species. In contrary to all other creatures, humans individualize themselves through providing every person with a unique name that serves as their identity for the rest of their life; likewise, humans, though constructive, are considered the superior species because of their ability to understand beyond the capability of wild animals and due to their…
