Evolutionary biology and Creationism are both alike and different in many ways. Evolutionary biology is known as an “interdisciplinary field”. That is because it is known to include scientists from a wide range of both field and lab oriented disciplines. Evolutionary biology includes scientist who have special training in mammalogy, ornithology, and herpetology. Creationism only has one creator, which is God. God is the one and only scientist and creator of Creationism.
Of course evolution plays a major role in both evolutionary biology and creationism. The common definition used for evolution is, “evolution is the process of change in the inherited traits of a population of organisms from one generation to the next.” One way evolution plays a major role in evolutionary biology is because the many scientists in the fields of evolutionary biology use the organisms from their field to answer general questions of evolution. Evolution plays a major role in creationism because creationism is all about how God created everything such as humanity, the Earth, the sun, and universe. Evolution is how the process of change in the inherited traits of a population of organisms from one generation to the next, and God created everything in creationism, which affected everything from past generations, and still affects change to this generation.
In evolution, mutations; which are said to be “changes to the nucleotide sequence of the genetic material of an organism” can produce new or altered traits in individuals in genes. A gene is usually defined to be a region of DNA that controls a hereditary characteristic. Natural selection is also known to be, “a process by which heritable traits that are helpful for survival and reproduction while harmful traits become rarer.” Natural selection usually happens when a person with a more advantage with their traits are more likely to reproduce successfully, so more people in the next generation...
...In the history of science vs. religion there has been no issues more hotly debated than that of evolution vs. creationism. The issue is passionately debated since the majority of evidence is in favor of evolution, but the creation point of view can never be proved wrong because of long standing religious beliefs. Human creation is seperated into three simple beliefs; creation theory, naturalistic evolution theory, and theistic evolution theory. The complexities of all three sides create a difficult dilemma for what theory to support among commom people, religious or non-religious.
The theories of human evolution tend to always cause a heated dispute in modern American society. Each theory presents its own evidence proving its acceptance, but lacks enough evidence to prove the other theories incorrect. All the theories that attempt to explain human existence fall under the categories of creation theory, naturalistic evolution theory, and the theistic evolution theory. The creation theory explains that a certain God, or God's created the humans, and evolution does not exist. The naturalistic evolution theory states that evolution is driven by purely natural forces, and is not controlled by any input from a god, goddess, or multiple deities. The theistic evolution is a mixture of both creation and naturalistic theories. The theistic evolution theory states that god created the world and guides the evolution process (Religious...
Check’s article “How Africa Learned to Love the Cow” explores the studies and research of Sarah Tishkoff on genetic mutation and evolution of, more specifically, the gene that codes for lactase and lactase persistence within individuals in Africa. The frequency with which these genes occur fluctuates dramatically, which is noted in Tishkoff’s study on African populations, and account for tolerance and intolerance of lactose within humans (Check). It is interesting to see that environment may affect genetic mutation within individuals as well. Tishkoff’s research on lactose tolerance within humans in Africa is a revolutionary prospect, which allows others to study the issue of lactose intolerance in adult humans and view evolutionary trends in varied populations of humans, bringing new information and proof of evolution to the table.
Only certain individuals from certain populations can tolerate milk as adults due to various factors, such as the presence of the gene that codes for the production of the enzyme lactase, natural selection, and vertical gene transfer. Lactase is essential for breaking down lactose, a sugar within cow milk that would otherwise pass through a human’s digestive system undigested (Check 1). Within adult humans, the gene that codes for the production of the enzyme lactase is sometimes inactive or missing, which causes the intolerance of milk and causes lactose to have “unpleasant results” (Check 1) if ingested by an...
...offspring behind than others, pass on more of their alleles and have a better success rate in dominating the population. (H-W assumes no natural selection)
Genetic Drift occurs in 1)Bottlenecks-large population goes through a catastrophe and a few thousand survive eg. Modern Humans 2)Founder Events-move out of home population origin into a new environment
-*in small populations, allele frequencies happen by chance
It decreases genetic variation and heterozygosity
Founder Events and Disease –in Newfoundland, ARVC occurs when muscular walls of human heart thicken; the spread of this disease comes from an ancestor that carried the gene for this disease
Gene Flow occurs in faster organisms in behaviour and movement (eg. a hummingbird vs. turtle)
(2. H-W assumes population is isolated)
-gain and loss of alleles - make 2 pop. dissimilar
Directional Selection-changes the average value of a trait eg. in giraffe necks, there was a selection pressure against short necks, since individuals with short necks could not reach as many leaves on which to feed. As a result, the distribution of neck length shifted to favor individuals with long necks.
Eg2. Artificial selection in agriculture is usually Directional Selection such as farmers select turkey with larger breasts b/c it’s more valuable
Stabilizing Selection- reduces the amount of variation in a trait eg. short height and tall height of sunflowers is balanced with an average height in order to gain the...
Yes there was a change because with the starting snail population there was a great variation from 1-7. After the crab began eating only the snails with the thickest shells survived. The snails with the thinnest shells were eaten by the crab. Only snails with shell thickness 4-7 were left after the crab had their meal. The original snails with thickness 1-3 were eliminated from the population by the crab. The crab will usually try to expend as little enrgy as it can to maximaize its happiness so the snails with thinner shells will likely be targeted first and eventually eliminated.
When predatory crabs are present in the snail population thinner shells were eaten much faster than when I was predator. The offspring that resulted only had thicker shells with predatory crabs but with me there were still crabs with thin shells. One reason is that there were four predatory crabs as opposed to just 1 which was me. Four crabs eat a lot more and much faster than me. Furthermore, since there are more crabs they would eat whatever crab came their way whether thick or thin while I was more picky and went for thinner shells.
There was no change. Even though predators were eating just as much snails, with natural selection if overtime snails stay constant, it means that its well adapted to its environment. If there is no variation in the population, there is no way to obtain new traits. The reason we get different shell thickness is because...

Synthetic Biologyvs. Natural Selection
Darwin first introduced the idea of evolution in his publication of The Origin of Species, on November 24th, 1859 (Campbell, 2005, p. 438). This opposed many traditional views as it was generally accepted that the beginning inhabitants of the world had no mutations in their genetic composition. His publication had two major points. The first being the modern organisms presently inhibiting the earth, differ from their ancestral species by a process called evolution. The other point he made was that of natural selection, as it is the mechanism for evolution. The organisms inherit traits from ancestors who were able to survive specific environmental conditions, passing these traits on to their offspring.
Darwin's revolutionary way of thought has led the way to discoveries in the field of evolution, becoming one of the fundamental concepts of modern biology. Many scientists design experiments illustrating Darwin's theory, as they tamper with the environment of the organism and watch it differ from one generation to the next. Other scientists move past the observation stage and start tinkering with the genetic composition of the individual organism, documenting its effects. This can be seen in bacteria and other microorganisms as scientists insert...
...scientifically. While in the world today mostly everything is being created from science although that might not have been the case back in the days. In this research paper I will try to show the difference between the two and how they are still one in the same. While this research paper is not designed to persuade you in your beliefs, it is a bucket of knowledge that will better educate you on the two.
The Creationismvs. Evolutionism controversy represents a clash between two ways of relating to the world (scientific/non-scientific). The central idea of biological evolution (scientific) is that all life on Earth shares a common ancestor, just as you and your cousins share a common grandmother. Creationism (non-scientific) is someone who believes in a god who is absolute creator of heaven and earth, out of nothing, by an act of free will. Creationists do not believe that all of today’s living things evolved from simple organisms changing slowly over time. Creationism opposes the idea of human evolution.
(Ruse, Michael, fall 2008)
Since the creation of the universe is typically explained by two popular beliefs. One being the scientific explanation and the other being biblical explanation. These are two very different explanations, and while I believe ones religious beliefs can have a role in which explanation one chooses to follow, one is free to choose...
Aim: To construct a field graph to study the local ecosystem at the Minnamurra estuary involving abiotic factors, transects and abundance.
Measuring abiotic factors
1. Measure the elevation along the transect line in centimetres using an inclinometer in each quadrat.
2. Measure the soil temperature in degrees using a thermometer by placing it in the ground in the quadrat.
3. Measure the air temperature in degrees using a thermometer by holding it up in the air just above the ground in the quadrat.
4. Measure the wind speed in knots using an anemometer held up in the air in the quadrat.
5. Measure the soil moisture in the quadrat using a soil moisture probe. Soil moisture is represented in a percentage 1%-100% with 100% being the maximum amount of moisture.
6. Measure the amount of sunlight in the quadrat using a lux meter.
Calculating the abundance of animals across the mangroves and salt marsh
1. Place a quadrat somewhere in the shoreward edge of the intertidal zone
2. Align the quadrat with a compass so that one side faces north and the other faces south.
3. Calculate the area of the quadrat in metres squared.
4. Calculate the abundance by first, finding the area of the quadrat in m2. Total number of individuals in each quadrat and the total number of quadrats. Average number of individuals per quadrat = total no. Individuals ÷ total no. Quadrats.
5. Estimation of abundance = Average no. Individuals per quadrat x Area of quadrat....
Breaking down glucose to release energy
Products are Carbon dioxide and water
Diffusion is … the movement of molecules from a region of high concentration to a low concentration until the concentration is equal.
Role of a human circulatory system:
Diffuse In – oxygen (O2), dissolved food (glucose) and water (H2O)
Diffuse Out – carbon dioxide (CO2),waste and water(H2O)
Respiration – releasing energy in cells
Breathing – getting air into and out of your body
When you exercise your heart rate and breathing rate increases
Heart rate measured – beats per min.
Breathing rate – counting the number of breaths in a min.
Muscle cells respire faster. Meaning- they need more oxygen and glucose and release more carbon dioxide.
A faster breathing rate means that oxygen can be taken into the body at a faster rate and carbon dioxide can be released faster.
Cardiac output = stroke volume x heart rate
Effects of exercise:
Ventilation – breathing
Respire – release of energy from food/chemicals
… is release of glucose without using oxygen. This produces lactic acid.
glucose = lactic acid + energy
Advantage: useful for muscles because it can release energy to allow muscles to contract when the heart/lungs can't deliver (O2) and glucose fast enough for aerobic respiration.
Disadvantages: Lactic acid is not removed from the body. It builds up in the body and the blood....
