The history of reptiles began when the first reptiles evolved from amphibians. Fossils of the first reptiles have been found in deposits from the early Carboniferous period (359-299 mya) and possessed characteristics that made them greatly resemble lizards; they were small in size, had four legs, were vertebrates, and possessed teeth that classified them as insectivores. These reptiles flourished due to the sheer amount of insects available around them, and by the end of the Permian period (299-251

Over 16,306 different species of plants and animals have nearly gone extinct. Soon many of them could disappear from our planet and we would have nothing but their bones, and maybe not even that. One of earth's most extraordinary animals, the Zippleboff, will soon disappear. This, in more detail, means that the Zippleboff's population declines quickly. In the last ten years around half of Zippleboff's have disappeared. Cornell scientists estimate that in the next 20 years Zippleboffs could disappear

Darwin’s impact on Society Charles Darwin was born in Shrewsbury, England on February 12, 1809. He was a great humored, pleasant man (“Darwin’s, Charles Robert.”). Darwin’s education was began by his older sisters after the premature death of his mother (“Darwin’s, Charles Robert.”). In 1817, he was sent to a (day school) in Shrewsbury, where he was found to be slow in learning; a year later he was entered at Shrewsbury School under Dr. Samuel Butler. He was then removed from school in 1825 and

innate rather than learned.” (What Does "Nature Versus Nurture" Mean?, 2014) People who take this extreme heredity stance are known as nativists. Their basic assumption is that the characteristics of the human species as a whole are a product of evolution. Each person’s unique genetic code determines individual differences. Simple things like eye color, stature and freckles can be attributed to the construction of your genes. But they also help explain why someone is gay or straight, or religious

Jason Billing Mrs.Werle AP Biology Summer Assignment 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. In 365 million year old rocks the amphibians had characteristics that were not similar to fish, but in 385 million they found fish that were dissimilar to amphibians. The scientists then looked

History has revealed significant periods of major mass extinction phases since the beginning of written history, and although extinction is a natural part of evolution, the current rate of loss is unprecedented. The extinction rate use to be one to five species per year. Today we are losing dozens species every day solely because of human activities. Habitat loss, the introduction of invasive species, and global

There are many factors on the environment affect on the organism’s life; these factors play a major role on the reproduction and survivals abilities of these living organisms. One of these important factors is the temperature, each organism has a certain temperature range that the organism can survive and reproduce on that range. Scientists know the performance of an organism by measuring the heart rate of the organism to indicate the ability of the living things. Du et al [2010] studied the temperature

When first reading The Jungle by Upton Sinclair, I couldn’t help but think of the term “social Darwinism”. This is a term that we learned in history last year and ultimately connects the biological concept of “survival of the fittest” to human interaction in society. This impression is seen many times throughout Sinclair’s work, but was most accurately depicted in the passages where Jurgis gets involved in politics and becomes friends with upper-class men such as Jack Duane. It can be seen that

is known as evolution, which Lamarck advanced his concept to natural laws. Naturalism beliefs have “natural laws and forces operate in the world” ideas that natural reasoning, rules, and regulations can answer miracles (Naturalism, 2015). English philosopher and sociologist Herbert Spencer most influential book was Principles of Biology. Spencer viewpoint of evolution was natural selection to human societies, and Spencer belief was “we must compete to survive, and reproduce” (Evolution, 2011). Spencer

Darwin, the most notable naturalist, collected, studied, and classified many organisms that no one in Europe had ever seen. His study of this amazing variety of organisms led him to develop his theory of ‘Natural Selection’, which explains how population evolve and how new species develop. According to the natural selection proposed by Darwin, in any population, there exists variation and an unequal ability of individuals to survive and reproduce, and only the best fir individuals survive and get
