Species richness

Introduction Squirrels are small rodents commonly known across the United States. There are over 200 squirrels species. They belong in the genius Scieridae(1). There size is varies from 5 inches to 3 feet long. The commonly known squirrel in Kansas is either the Eastern Fox Squirrel, its recorded size varies from 18-28 inches. The genus name for the Easter Fox Squirrel is Sciurus Niger(2). Animal activity can be measured in the observation of animals in a certain location. The Activity can…

these two species. History About 155,000 years ago, the Homo sapien has arisen from previous ancestors such as the archaic H. sapien and H. erectus (Rodrigues, 2012). Most of our ancestors were discovered and identified in…

This is another way we have evidence of relatives in evolution when finding that there are more closely related relatives. The author states, “We expect to find, in the genomes of many species, silenced, or “dead,” genes: genes that once were useful but are no longer intact or expressed” (Coyne, 2009, pg. 67). When another specie forms into another are basically genes that form ancestral structures. The author also talks about bad design…

Many things live in your mouth. Bacteria live in it. You ask, “What kinds of bacteria? Why can’t we sense it? Is it good or bad?” Be brave, take a reading adventure and find out answers to all these questions, and more. How much bacteria exactly? A lot of bacteria live in your mouth, colonies, and colonies. About 6 billion live in your mouth. That’s interesting because about 7.3 billion people live on earth. All those bacteria that live in your mouth actually live in diverse communities,…

removed of technology, this species would not have survived as long as we have: since we do not have much hair, we would have frozen to death because there would have been no way to create and keep a fire going to warm us up enough to stay alive and keep predators away. If there was an encounter with a predator, the predator would have most likely prevailed due to our inferiority in strength and speed. The aid of technology has made us evolve into the smartest species dominating the earth. As we…

Tullis, Paul. "When You Walk Into a Zoo, Are You Helping Animals or Hurting Them?" TakePart. N.p., 02 May 2014. Web. 16 May 2017. . Paul Tullis, an editor at TakePart and writer for the New York Times Magazine, tries to answer the question “When you walk into a zoo, are you helping animals or hurting them?” Tullis covers many different topics and stories throughout his article providing evidence that zoos are helping animals along with zoos not helping them. Tullis believes his…

John Endler conducted two studies documenting the relationship between guppy coloration patterns in correlation to predation and sexual selection. Endler (1980) references his previous field study (Endler, 1978) in regards to coloration patterns present in the presence and absence of different predators. The relationship that was found there (Endler, 1978) was that in areas of high predation, coloring was less conspicuous and more closely blended to their background, whereas in areas of low…

with other organisms. A result of natural selection is an increase of offspring, which leads to an increase in the population of specific species.…

As they approached the beach, they saw the purple flags and no swimming signs. They asked the lifeguard why the purple fag was up, and the lifeguard said one word, “jellyfish.” Jellyfish can paralyze and kill other small animals, and sometimes they kill humans. Most jellyfish are transparent and have very long tentacles. These are good qualities for a predator. However, now you can buy anti-jellyfish sunscreen. Many cultures cook and eat jellyfish, and we are using them in medical research.…

Likdisha AP Biology Essay #2 The modern synthesis incorporated Charles Darwin’s theory of natural selection and many other fields of science, including genetics, to explain evolution more accurately. When Darwin wrote “On the Origin of Species “, he only explained the first mechanism of evolution, which was natural selection. The modern theory of evolution now highlights three more important mechanisms for evolution, which are mutations, genetic drift, and gene flow. Many fields…
