Evolution Lab Report

Charles Darwin, a naturalist born in 1809 England, traveled around the world on the HMS Beagle from 1831-1836 (Desmond). He made observations on land for three out of the five years he traveled around the world; his most significant findings were recorded on the Galápagos Islands. The most crucial evidence of evolution, a theory that Darwin is known for, consist of the different species of Galapagos tortoises and finches that Darwin observed. He noticed that depending on the different islands similar finches had different variations of beak size and shape. To add, he observed that the tortoise's shell shape and neck length varied based on which island they resided on. Darwin made the observation that depending on each island, which had different

Evolution is a change in the characteristic of living organism through time. Modern synthesis, one of the greatest intellectual achievements of biology, could explain how mutations and natural selection could produced large-scale evolutionary change. There are 4 mechanisms for evolution to occur; mutation, gene flow, genetic drift and natural selection.
Although, there are a number of misconceptions about evolution; it does not explain the origins of life, it is not progressive, natural selection is not about the survival of the fittest individuals in a population, humans are not currently evolving, it does not make organism better designed nor does it gives organism what they need to survive. This essay will describe further, 3 common misconceptions

The reason for doing this lab is to study evolution using small population of finches on two different islands. I used different charts and graphs to find limitations on natural selection. Then find the effect evolution will have on beak and population over a certain time period. Using three different assignments I have to develop different hypothesis comparing and contrasting the average beak size and population size changing rain fall, beak sizes, population and island size on Darwin’s and Wallace experiments.

The purpose of this lab is to better understand the process of natural selection and its effects on a population by conducting a stimulation. The stimulation consist of predators (students with either a spoon, fork or a knife) and prey (different types of beans). Furthermore, students will be able to determine how phenotype (bean color and utensil used by the predators) influences natural selection. Students will also demonstrate their quantitative skills by determining the predator survival and reproduction, bean survival and reproduction, and by calculating the total percent of the population. Additionally, students will be able to identify the occurrence of evolution by natural selection after the end of generation three. Moreover, students

The Evolution Lab simulates environmental situations to determine effects on evolution over periods of time. This lab experiments with the evolution of finches on two different islands over 100, 200, and 300 years. By manipulating parameters that influence natural selection, the effects that natural selection have on the evolution process can be studied.

In the Annenberg Learner, Video on Demand series session 6, Evolution and the tree of life, various professors or scholars discussed the evolution of life. The session began with a beautiful photograph of Harvard University of Natural History. Next, a narrator introduced the Museum of Comparative Zoology located in the basement of Harvard. The basement holds the reptile and amphibian collection. The narrator pointed out that the century old jars containing specimens of bodies along with their DNAs carry clues that help scientists to reveal how evolution has shaped and reshaped the living planet also how to make sense of life.

Anatomical Evidence – evidence relating to the structures of organisms and how they have evolved over time and might share a common ancestry.

1. Did the construction of the phylogenetic tree based on the 14 living Caminalcules change the way you would group Caminalcules species in your taxonomic classification (chart)? What does this suggest about classification based on strictly of similarity versus evolutionary relationship?

Scientist show the ancestors of humans and chimpanzees, and show the similarities between them. Scientist also use Darwin's theory to show the change over time and develop natural selection to compete in its environment. The purpose of this lab is to explain the theory of evolution by observing skulls fossils to prove the change from quadrupedal

Evolution is the key thread running throughout this text, signifying its importance to the author and readers. It is emphasized greatly because that is how we understand ourselves, our past, present and even the future. Through evolution we have discovered when the first organisms came around and how modifications led to the first fish to migrate to land about 375 million years

The course dates back to centuries and we all have learnt the gist of evolutionary biology, including Darwinism, natural selection, genetic variation and more. But what would make the course a little better is to include some articles like the one used in this paper. After reading the extended evolution paper, I browsed around the science alert website and saw a couple of interesting articles that could of be integrated in our course. This being said, students would have a more up-to-date knowledge of evolution and have a better time understanding the material if newer information is incorporated with the older information taught in

In lab 2 we are using computer simulations to investigate the four forces of evolution. The four forces of evolution include mutation, gene flow, genetic drift and natural selection. Mutation is a way for new alleles to be introduced into the population and is completely random. Gene flow is when a group of individuals migrate into a new population and bring with them new alleles like mutation this can also be random. Genetic drift is when alleles are taken out of a population because of some random occurrence unrelated to the alleles like a natural disaster etc.

The article “Catching Evolution in Action,” demonstrates that modern day science are beginning to look at the evolutionary biology not only through observations but also in the experimental form. In the case of experimentation, biologists study the evolutionary changes in the “guppies” in streams. In the past, evolution was considered by scientists only to be observed and drawing conclusion and hypothesis through deduction and induction techniques (“Catching Evolution in Action”). However, those procedures started to change because scientists today are able to produce experiments in nature unlike previous general studies of animals. By conducting experiments through controlling their selection of what they will observe, scientists have the

The word is now accepted to mean the change of nonliving chemicals into simple life-forms into more complex life-forms and finally into humans.” (Answers in Genesis 1). Despite the many claims that “evolution” simply means a change, scientifically speaking it means much more. Evolutionary ideals describe changes that allow scientists to date life on the earth to be 4.5 billion years, to trace the entire living population of every animal, insect, plant, virus, and bacteria back to one simple cell, and to conclude that the first cell supposedly came into being sporadically from a pool of organic molecules (Archean 1). Science cannot factually support evolutionary concepts because evolution cannot be tested; observation holds a critical role for experiments to take place, yet spontaneous creation of a cell has not recurred since the alleged first living cell created itself. Evolution cannot be proven, and therefore, the public school system should not teach evolution as fact, especially with no exposure to alternative concepts.

Biodiversity presents occurrence of variety of species and their natural community in which they live. By the definition it is “The degree of variation of life forms within a given species, ecosystem, biome, or an entire planet. It is a measure of the health of ecosystems and is in part a function of climate.” (Rutherford) Ecosystem is on the other hand, “ community and its abiotic environment”( Rutherford). Biodiversity exists in every ecosystem, weather it is big one, or just ecosystem of one garden, it has the same importance because without it nature loses its ability to perform major functions needed for life on Earth, as it is oxygen production. Trough this investigation, two different ecosystems will be explored and
