Natural selection

Evaluate the impact of increased understanding of the fossil record on the development of scientific ideas about the history of life on Earth Improved understanding of the type of fossilised arthropod known as a ‘Trilobite’ allowed for subsequent increases in development of the theory of evolution. Since it’s initial drawing by Rev. Edward Llwyd in 1698, multiple improvements in technology as well as collection of specimens have painted a detailed portait of the nature of trilobites as well as…

than a literal seven-day creation. Though this revelation initially struck me as blasphemous, it was actually an introduction to the believing game. As my father described his viewpoint, I began to consider previously disregarded evidence for natural selection and a universe billions of years old. I suspect that if my father had not helped me to see other ways of looking at this apparent contradiction, I would have entered college with an ill-informed suspicion of evolution and anyone who taught…

environmental conditions: on narrow 0.7-centimeter- wide wooden dowels and on broad eight-centimeter-wide boards (Losos 2001). It was found that the anoles that were raise on the narrow surface had shorter legs than those raised on the broad surface. Natural selection may have been another factor acting on the anoles. Very much like Darwin finches of Delphin Major a island and in string of island known as the Galápagos Islands, which showed a increase in finches with bigger deeper beaks in the…

These scientists had similarities and differences in their motives, influences, and personal attributes that affected the development of their respective sciences. Humboldt’s main motive in his scientific studies was to find connections in the natural world (Wulf, 2015). In his travels across the earth, he was not searching for one particular thing, rather he was searching for everything. His desire was to search for…

have been many theories that scientists and people have created. They can deal with anything from people, the world, or even food. These theories are later proven to be true or can be proven wrong Charles Darwin came up with the theory of natural selection. This gives an explanation of evolution, and how plants and animals have adapted to survive. He believed that everything happens for a reason and that one thing led to another. Thomas Malthus’s theory stated that there are more people…

scientists interested in the mechanism of evolution. Lamarck’s theory was oriented around how organisms change according to their surroundings during their lifetime and pass these traits onto their offspring. While Darwin’s theory, known as natural selection, believed that each organism has a differential ability to survive and reproduce due to variation in characteristics. This is why the term “survival of the fittest” was coined. These characteristics will then be more likely to appear in the…

Measurable Outcomes 1. Describe and demonstrate knowledge of modern evolutionary synthesis, natural selection, population genetics, micro and macroevolution, and speciation. I learned about the speciation of animals in Module 3 and in Module 4 I learned about modern evolutionary synthesis, natural selection, population genetics, and mirco and macroevolution. I was able to learn all this information due to the chapter 46 and chapter 47 notes, the online textbook, and the PowerPoint notes. This…

Reaction Journal Five: Functionalism This week’s reading was over the beginnings of the radical functionalist movement that was lead by Charles Darwin. Darwin was more concerned with how an organism functioned and adapted to change than the perception, sensations, and the structure of consciousness as his fellow psychologists Wundt and Titchener were. Darwin lived a life of privilege and traveled extensively during his lifetime. During his travels, he observed many animal species and made…

this planet, Earth. To survive in this planet, each bugs uses adaptation, which makes each insects unique and special. The definition of adaptation is “the ability of a species to survive in a particular ecological niche, …especially through natural selection.” (Dictionary.com) Through all the ‘adaptation skill’ that bugs use, this particular insect mentioned in article, Podisus maculiventris, uses a special skill when laying the egg. Podisus maculiventris, also known as soldier stink bug, is a…

earliest form of life. This common ancestor theory is backed up evidence that supports it such as fossils and the genomes of many species that have been compared and found to be extremely similar. There are several mechanisms to evolution such as natural selection and genetic drift. It is important to note that genetic mutations lead to variation, and these mutations can be beneficial and will be passed down from generation to generation. This is all part of evolution, as the changes within…
