According to Dr. James Krupa of The University of Kentucky “evolution is the foundation upon which all biology rests.” In biology, evolution is the genetic change in characteristics over generations and is dependent on the process of natural selection. ‘The theory of evolution is based on the idea that all species are related and gradually change over time’ (Genome Campus, 2017). Genetic variation is vital to evolution as it affects the physical characteristics or phenotypes of morphology. Natural Selection is affected by environmental factors that act upon a population and result in the mutation of organism through offspring. These mutations enable individuals to adapt to their environments in order to survive, find food, avoid predators and …show more content…
Charles Darwin originally produced a theory after monitoring Finches on the Galapagos Island that ‘individuals that are poorly adapted to their environment are less likely to survive and reproduce. This means that their genes are less likely to be passed to the next generation. Given enough time, a species will gradually evolve’ (BBC, 2014). For example, ‘Grey Treefrogs (Hyla Versicolor) and Green Treefrogs (Hyla Cinerea) in the Southern United States seem to be ecologically equivalent. While Grey Treefrogs and Green Treefrogs seem to occupy the same habitat, when we look closer we can see that through their ranges overlap, Grey Treefrogs live farther north than Green Treefrogs. We can also see the Grey Treefrogs prefer wooded areas with temporary pools, while Green Treefrogs prefer more open wetland areas with cattails and other aquatic vegetation. On a tree in a wooden area, the Grey Treefrog is much harder to detect. In a wetland, the situation is reserved’ (Michigan State University, …show more content…
Fossilization is the process where bones evolve into fossils and preserve in different environments that help to sustain ossein. Some environments include permafrost, amber, peat, dry air, or within sedimentary rocks. There are several different ways that fossils can be classified; this includes original, replacement, carbon film, and indirect fossils. ‘Original fossils for when part of the organism is preserved, with chemical composition being about the same as it was when it was living’ (Pearson Science, 2018). ‘A replacement fossil forms when a part of the organism is chemically changed into another mineral. Replacement fossils commonly form when the calcium carbonate found in shells and bony skeletons turn into another mineral such as silica, also called silicon dioxide’ (Pearson Science,
The Loggerhead is an endangered species. Between 1997 and 2007, around 70% of their east coast yearly nesting population was lost as a result of shrimp trawling and development in nesting areas. The Loggerhead Turtles habitat in Gnaraloo is vital for their survival. The female loggerhead usually digs her nest at night. She digs her nest with her back flippers, about 18 inches beneath the surface. When she lays her eggs they fall to the bottom of the nest and pack together after she lays the eggs she tops off the nest with sand. The hatchlings will incubate for 60- 80 days. Loggerheads nest on ocean beaches, they lay their eggs, immediately after hatchlings emerge from the nest, they begin a period of frenzied activity. Hatchlings are primarily
The white Ogeechee tupelo tree is a shrubby tree that grows along rivers and in swamps in Florida and other parts of the South. It is called the white tupelo tree for short, and it is well-known for its beauty and for the food it provides people and animals.
We call the formation of fossils “fossilisation”. Fossils form in a really unique way, and it depends on several factors. It is quite hard to have all the favorable conditions to form a fossil. The corpse of the dead animal is usually eaten, or it is even affected by the presence of bacteria before the process of fossilisation can start. Erosion and corrosion are also responsible for destroying harder parts of the body, such as the bones. In order for the process
Fossils are very useful in putting together the history of organisms and how things have evolved over time. They can be found deep in the ground. The long process that makes this possible is fossilization. Fossilization is the process by which the remains of a plant or animal fail to fully decompose and in time, converts into a fossil. In order for organisms to turn into fossils, certain conditions must be met. The soft parts of an organism will often decompose or be consumed by scavengers. Therefore, organisms with hard parts like a shell are more often fossilized, leaving behind the skeleton. Even hard parts such as the skeleton can be destroyed by nature such as waves or by other microorganisms. Most importantly, the chances of fossilization decrease with greater exposure to
The definition of Evolution is ¨the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth,¨ (Dictionary.com, 2018). Although, the actual definition is hard to comprehend. Some consider Evolution to be a somewhat ridiculous topic that is far from true. Though others believe that, ¨Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology,¨ (Than, 2018). The main idea of Biological Evolution is that all life on Earth share a common ancestor. The term is a way of understanding life.
Once upon a time there was an abandoned castle on a tall mountain. The castle was in Cabin Creek and in that valley there was an entire village full of people. The castle was an abandoned abut three years ago by a King, Prince, Queen, and many servants .They left the castle because their whole village was up to no good. The village people would try and set places on fire and throw rocks into other villagers home. To make matters worse, an evil wizard came an put a spell on the Cabin Creek village because they were being so bad. The spell was about a dragon would come and set this whole valley of houses on fire 2 times in 2 days. Tragically this leaves the the village people six days to prepare before the dragon appears. The village people needed a hero to save them. So the next the went out on a search for a hero to save the day at last.
In the pacific northwest, there exists an insect the size of an apple seed. It feeds on the phloem of trees, leaving them mutilated, their bark eviscerated and leaking sawdust. Victims of choice include lodgepoles, western white pines, and ponderosa, but any gymnosperm will do. For the mountain pine beetle, Dendroctonus ponderosae, the invasion means reproductive success. For the tree, it means slow death.
More small leafthoppers was left, and there was less orange and large leafhoppers. Small leafhoppers may have the capacity of better heat dissipation than the larger ones, they have metabolism that is more suited to global warming. The leafhoppers with lighter color have a difference in their metabolism and it may explain their situation. A possible reason as to why they were unable to survive as efficiently as the darker ones is because their energy calorie needs was higher to produce offspring in warm climate. It is possible that color is linked to characteristics that are passed on to future generations, but color itself does not necesseraliy have a real direct role for survival.
Each society was a small kingdom and the leader was called cacique. At the time of Columbus, there were five different kingdoms on the island of Hispaniola. The Indians practiced polygamy. Most men had two or three wives, but the caciques had has many as thirty. It was a great honor for a woman to be married to a cacique. She not only enjoyed a materially superior lifestyle, but also her children were held in high esteem.
Most people would be surprised to learn that scientists have an interest in rubber ducks. However, by tracking the journey of 28,000 rubber ducks and other toy animals, scientists gained extremely valuable information about the oceans.
Humans can be acknowledged as dependent species whom need to necessarily rely on other humans to seek happiness in their life. Majority of happiness are originated from the bond and relationship people make with each other. Values and meanings of relationship cannot certainly be measured with tangible objects; yet, respect and feelings of love can only be obtained by truly understanding one another. In a novel, “Embers,” the author, Sandor Marai, articulates the true friendship between Konrad and Henrik. The dream, passion, and youth which Konrad and Henrik shared burned furiously until lust and envy within human nature had devoured the burning flame. Even though
For my “out of classroom” experience, I attended an introductory class for the green dot training program provided by Bergen Community College. The host was Deborah Ajagbe who is the Bystander Intervention Facilitator and the Green Dot Coordinator. Her opening statement was how she desires to create a safer community not only in college campuses but everywhere. She presented us with a map covered in red dots at places such as schools, homes, stores, and parks. The red dots represent a “hit”, or a place where abuse in some sort of form takes place. It can also be a scene where violence is tolerated. However, the green dots symbolizes a “safe” zone where violence is always spoken against and where people choose to reduce harm. Proactive green
The Theory of Evolution was created by Charles Darwin and also Alfred Russel Wallace in 1858. The Theory of Evolution is based off of a branching tree of life that believed all shared the same common ancestors. Natural selection is the survival and reproductive outcome of random varying organisms. The evolution is change in genotype, which is allele frequency and over time it gives rises to all the different and diversity of species. Natural selection changes a species in many different ways. It can change by the population, climate, size and color over the time period of several generations. Microevolution and natural selection are very similar. Microevolution is the change in evolutionary with in a species or within a smaller group of different
Have you ever wondered how fossils form in the environment? Will, if you didn’t this is for you. The first stage of the “Fossilization” is when a type of animal dies in a watery environment and is then covered by mud. Then the soft tissues like muscle decompose leaving behind the hard bones, and maybe shells. Next, over time minerals like rock, soil, and others settle over the bones and hardens them to rock along with the others. Then you have your fossil. One of the most unusual fossils is when
Biological evolution is the name for the changes in gene frequency in a population of a species from generation to generation. Evolution offers explanation to why species genetically change over years and the diversity of life on Earth. Although it is generally accepted by the scientific community, Charles Darwin’s theory of evolution has been studied and debated for several decades. In 1859, Darwin published On The Origin of Species, which introduced the idea of evolutionary thought which he supported with evidence of one type of evolutionary mechanism, natural selection. Some of the main mechanisms of evolution are natural selection, mutation, and genetic drift. The idea that all life on Earth shares a common ancestor has been around for
