Biogeography

Common animal structures have also support evolution by using comparative anatomy to show common ancestral traits through stages of transition. The science of biogeography has examined living species and compared them to local fossils to determine whether they are similar in structure, and when they are, this is an indication that one is derived from the other. In addition, embryological studies examining similarities…

Gorai M, Neffati M, and Tlig T (2007). Germination responses of Diplotaxis harra to temperature and salinity. Flora 203: 421–428 2a) Successful colonization of plant species is reliant on fruitful seed germination, which is consequently influenced by various environmental factors such as temperature, salinity and soil moisture. The authors hypothesized that temperature is a determining factor in relation to germination behaviour, affecting seeds’ tolerance to salt. Testing germination…

Darwin’s theory of evolution is an idea that all living organisms are related and have a common ancestor. His broad theory speculates that progression of life from non-living and emphasizes an all in all realistic “descent with modification”. In other words, complicated creatures emerged from uncomplicated creatures consistently over time. This meaning stray genetic mutations happen in an organism’s genetic code. These mutations, which are useful, are retained as they help in survival, also…

world’s greatest scientific adventurer explorers. After Wallace’s eight-year exploration of Asia and wrote two books, one of which was “one of the finest scientific travel books ever written.” A third reason for Wallace’s importance is his work in biogeography. Alfred Russel Wallace made a book called, Geographical Distribution of Animals (1876). The fourth reason was the co-discoverer of natural selection (Alfred Russel Wallace –…

located on the west coast of South America, Chile, and Argentina. Most of the Valdivian Coastal Reserve rainforest is located in Chile. The forest has many bamboos and ferns, and evergreen trees. According to Veblem Delmastro, who is an expert in biogeography, forest ecology, landscape ecology and the ecological aspects of global environmental change says that Chile has faced many disturbances to their forests due to…

Evolution as a Lesson According to Dennis O’Neill, biological evolution can be defined as, “genetic change in a population from one generation to another” (“Early theories…”, n.d.). Contrary to what some may believe or have been taught, biological evolution and evolutionary theory do not suggest that humans come from monkeys. Rather, they suggest that organisms share a common ancestor somewhere down the line, and that that common ancestor can be held accountable for similar traits among…

Robert Brown Biology is a very broad topic and many scientists have contributed to the biology world. In this paper I will be talking about one of those people who had a major contribution to the science community. “Robert Brown was born on December 21, 1773 in Montrose Scotland. He died on June 10, 1858 at the age of 84 in London England” (Britannica 1). Robert Brown most recognized by how he described the “cell nuclei and the continuous motion of minute particles in solution, which came to…

Student number: 1004563643 Week: 2 Day: 1 Time: 1:30-4:30 Room number: RW 104 TA: Lisa Erdle Species number: #17 Do the colour of the cheeks patches of Probosciger atterimus affect its ability to be chosen as a mate? Introduction: A distinctive feature in the Probosciger atterimus (Palm Cockatoo) are their red cheek patches. This trait is found in both males and females and hence is not a product of sexual dimorphism. Palm Cockatoos are weak seasonal breeders having infrequent and…

cultures are different. To quote Jared Diamond, “In short, Europe’s colonization of Africa had nothing to do with differences between European and African peoples themselves, as white racists assume. Rather, it was due to accidents of geography and biogeography—in particular, to the continents’ different areas, axes, and suites of wild plant and animal species. That is, the different historical trajectories of Africa and Europe stem ultimately from differences in real estate”. As it turns out,…

slave” sentiment, widespread adoption of new ideas, foods, clothing, and tools occurred throughout the Old and New Worlds. If interactions were only taking place under the context of annihilation and with disregard for the learning about culture and biogeography of other groups, then how can European willingness to adopt the rituals of Native American tobacco and chocolate consumption, or the near obsessive documentation of African and American plants and animals be explained? Whether Europeans,…
