Issues Related to Genetic Diversity Genetic diversity is related to many different characteristics. “Genetic diversity refers to the number of different species as well as the diversity within the species.” (www.biology-online.org) The genetic diversities provide a way for the world to comply with the changing surroundings. As the world changes, the more creatures will adapt to their proper environments. The creatures offspring will have a higher survival rate. Genetic diversity is important

fishing gear, harvest, and habitat impact. Further, an endangered species is specie that is a risk of extinction for example; Giant Panda is at risk due to “habitat fragmentation and loss. The area in which the pandas live in is becoming smaller due to human activities such as logging, farming in forests and road building” ( San Diego Zoo Animal, 2013). Extinct species, is a “species, organisms that have become extinct, either in the wild or completely for example, Tyrannosaurus Rex Reference Freedman

in determining evolutionary relationship. Second issue that related is sexual reproduction. What is sexual reproduction? According to Concepts in Biology, “the propagation of organisms involving the union of gametes from two parents," (2008). In human form the males carry sperm which are small and motile. The female carry eggs which provide food for embryo. In addition, male his sex organs main purposes are to produce the sperm and deliver it in the reproduction tract of a female. However, asexual

the biggest factors is habitat destruction. Habitats are constantly changing due to the earth’s constant change in climate and movement, although that is only a slight change. The biggest component to habitat destruction is the result from human activity. Human activity within the last century has been the driving force in destroying habitats through pollution, greenhouse gases, urbanization and abuse of natural resources. Through marine pollution many of the aquatic animals are unable to survive

Change & Scientific Understanding Evolution How our understanding of evolution has changed over time. Our scientific understanding has changed over time. • Early cultures explained the natural world through myth, ritual, and tradition. • Initial attempts at science included the establishment of a uniform calendar or efforts to curb disease through non-supernatural elements. • Simple observation and mathematical understanding (ie. Pythagoras) created concise reasoning on why

evolutionary and biological species. Speciation, according to Darwin, “is this process of multiplication, occurring when one population splits into two reproductively isolated populations” (Charles Darwin and Evolution, 2009, para. 4). Darwin’s idea was that, through both gradual evolution and isolation, species will eventually turn into two distinct species. There are three examples of speciation that can further explain the process of speciation. Those examples are; allopatric speciation, sympatric

ability to see altogether. How did that happen? How can evolution cause a species to lose a trait? It’s a mystery that evolutionary scientists have been struggling to unravel. The search for an answer gives us a fascinating look at how evolution works. Regressive Evolution We usually think of evolution as a process in which species acquire new traits. But in cave fishes we have an example of regressive evolution, a process in which species lose a trait—in this case, the ability to see

Inherit the Wind “Inherit the Wind” is a riveting tale about what is right and wrong, Religion or Evolution. I have chosen to Write about Drummond and his ideologies and views on not only the bible but evolution as well. Drummond, being the defense attorney for Cates, he argues against a biased court to prove to a well religious town that not only is Cates innocent for believing in Darwin’s evolution theory, but that the law should not demand everyone to have one way of thinking. From the very

Microevolution This is both a necessary step in covering the gamut of arguments in favor of evolution and the step that will least impress dyed-in-the-wool Creationists. Dawkins does a good job of explaining some ingenious experiments that demonstrate just how rapidly evolutionary change can occur. He describes a decades-long (and still ongoing) experiment involving E. coli bacteria, and another involving wild guppies in South America. Both experiments show conclusively that natural selection
