Cladograms are a way for us to observe and analyze characteristics and evolutionary change between two phylums. Starting out with a character matrix allows us to determine synapomorphies and apomorphies between theses two group‚ allowing us to construct the cladogram (Reece). My cladogram consisted of various phylums from the Animal Kingdom. The outgroup for my cladogram was the Choanoflagellates due to the fact that “they are the closest‚ living‚ unicellular relatives of animals” (Leadbeater).

all biological sciences‚ and it lays the foundation for various scientific schools of thought. However‚ as in all things‚ there are misconceptions that arise such as: Indivual evolve‚ evolution is a linear increase in complexity‚ the goal or the evolutionary process is optimally or perfectly adapted organisms‚ evolution is a random or chance process‚ and finally‚ natural selection is the same thing as evolution. First and foremost‚ indivual do not evolve. Evoluntary change is based on the changes

likely occurred through natural selection‚ and from common descent. Darwin ruled out that such differences might be based on chance from random mutations‚ and concluded that much like selective breeding‚ the variation of species is due to an evolutionary process where by such plants and animals which had made these changes were more adapt at survival and procreation of the species. This has come to be known as‚ the process of Natural Selection. Decent with Modification as defined by Perry (2013)

caused by the need of survival. Natural selection is the process by which biological traits of an organism become less in common in a population over time. This process can even result in a different species. Polar bears have gone under a series of evolutionary changes over time to help them survive in conditions on the planet some such adaptations include larger paws‚ thicker white fur‚ extra fat to keep them warm and more recently they have developed polar bear type teeth.

Lamarck‚ French zoologist‚ one of the founding fathers of modern evolutionary doctrines (E. Jablonka and S. Gissis‚ 2011)‚ approached the evolution question after transferred to zoology field at his 50s and gradually found out that “creationism” was doubtful (Ralph F. Shaner).

zebra stripes According to ontological evidence‚ zebras’ background coloration is black. The white stripping appears at a later developmental phase. The development of zebra stripping can thus be viewed as an evolutionary response (Egri et al.‚ 2011). Any discussion regarding the evolutionary purpose of zebra stripes is inevitably traced back to Darwin and Wallace. While Wallace suggested that zebra stripes developed as a camouflaging mechanism against attacks from predators in tall grass‚ Darwin

Evolutionary Medicine For many years‚ evolutionary principles have helped with many different aspects of the medical field. These principles have significantly helped with providing scientists with helpful information in understanding different illness‚ and issues that arise in the medical field. More specifically‚ the cooperation of evolutionary biology with modern medicine has helped with understanding antibiotic resistance and susceptibility‚ spread of disease‚ and development of cancer.

Major Influencer For those of you who took biology last year and did not pay attention when we were learning about Charles Darwin and Natural Selection‚ here is your chance to learn how he made a big impact to his time. Charles Darwin‚ a Naturalist and an Influencer‚ revolutionized science from his theory of evolution by Natural Selection. Expanding on that idea‚ He developed his Natural Selection theory by going on a 5 year survey trip on the HMS Beagle around the world suggested by his mentor

Now‚ scientists have proven for certainty that evolution is an undisputable fact by the observations in modern sciences from molecular biology‚ direct observations (biogeography)‚ fossil record‚ embryology‚ and comparative anatomy. We are surrounded by life all around us. Whether it be plants‚ bacteria or animals‚ we are all related. We look nothing alike sometimes‚ but we share a common

1. There were several pre-Darwin explanations of evolution. Choose any one or a few of these and compare them to the accepted Darwin theory of Natural selection. A pre- Darwin explanation of evolution would be Jean- Baptiste de Lamarck’s theory of acquired characteristics. Which he thought that evolution and adaption to the environment does occur and causes diversity. His theory was that species inherit acquired characteristics and that more complexed organisms came from less complexed ones. Darwin’s
