Fossil record is evidence of evolution because of the fossils that scientist have found. Over the past years scientist found fossils of the same animal but with different features and how it changed over the years. For example a horse, scientist found the feet of horse and put them into a line and started describing all of the changes that it made. At first the horse had claws in the end the horse ended up taller and with hooves to support the horse. So that explains the change over time which is evolution. Biogeography is another evidence of evolution since it’s the study of study of the distribution of plants and animals throughout the world. Well some of the animals all over the world are alike. For Example, mice, there are two different kinds First is the Mus (Rodent) , it’s know for house pet that is mostly kept in houses and are small. They live in Eurasia to North Africa. The other one is the Dasycercus (Mulagara) and look different than the Mus but they still have come of the characteristics. They live in central Australia. A lot of animals all over the world have one similar looking creature and it all comes back to change over time and Pangea. Once all the animals looked alike and when the world separated, they each started changing and adapting to their environment.
Molecular Homologies is an evidence of evolution. According to Darwin’s theory of common descent, the homologies represent characteristics inherited with some modification from a corresponding

Abstract: Evolution and Common Ancestor Essay

Understanding evolution helps us solve biological problems that impact our lives. There are excellent examples of this in the field of medicine. To stay one step ahead of pathogenic diseases, researchers must understand the evolutionary patterns of disease-causing organisms. To control hereditary diseases in people, researchers study the evolutionary histories of the disease-causing genes. In these ways, knowledge of evolution can improve the quality of human life. Evolution played an important…

I. Early Ideas about Evolution (10.1) A. Early scientists proposed ideas about evolution 1. Evolution- process of biological change by which descendants come to differ from their ancestors 2. Other scientists besides Darwin came up with idea B. Four scientists important in development of evolution theory 1. Carolus Linnaeus (1700’s)- developed classification system to name living things (grouped by similarities) 2. Georges Louis Leclerc de Buffon (1700’s)- proposed species shared ancestors…

Evolution: Unifying Theme In Biology

The theory of evolution is a unifying theme in biology. A lot of things in biology revolves around evolution. Evolution is the explanatory framework. There are a lot of evidences that backs up the claim that evolution is a unifying theme in biology. One evidence is fossil. Fossils are a record of life that existed in the past. Fossils can come in several forms ranging from preserved remains to permineralization . Scientists think about the age, location and what the environment was when they are…

Montsechia Vidalii

well-preserved fossil is the answer. More than 100 years ago in central Spain and near the border of France one of the greatest fossils was found, and it was formed by limestone deposits over millions of years (Scientific American, 2015). For years it was believed the first flowering plant on earth was Amborella, until a couple months ago (Scientific American, 2015). David Dilcher, a paleobotanist worked with a team lead by Bernard Gomez where they presented evidence that a fossil uncovered more…

Fossils: The Seven Pillars Of Evolution

the theory of evolution by comparing 1) fossil records, 2) structural similarities among organisms, 3) the geographical distribution of organisms, 4) embryological similarities among organisms, 5) patterns among organisms, 6) the molecular similarities among organisms, and 7) the direct evidence of evolutionary changes in laboratories and the wild. These seven “pillars” of evolution explain the unity and diversity of life; how ancient organisms have evolved over time from a common ancestor to organisms…

The Misconceptions In Charles Darwin's Theory Of Evolution

Darwin presented his theory of evolution. Evolution has many misconceptions such as: explaining what evolution is and how evolution works, what scientist believe today and how evolution is used in today’s medical field. First, most people believe that evolution is the accusation people came from monkeys, however that is just an example of evolution. “Darwin’s general theory presumes the development of life from non-life and stresses a purely naturalistic (undirected) ‘descent with modification’” (“Darwin’s…

Chapter 1. *Biological Evolution Change in the properties of groups of organisms over the course of generations. *Populations do evolve: they undergo descent with modification . *No more dramatic example of evolution by natural selection can be imagined than today’s crisis in antibiotic resistance. *As the use of antibiotics increases, so does the incidence of bacteria that are resistant to those antibiotics; thus any gains made are almost as quickly lost. *Essentialism Variation is accidental imperfection…
