Why are island chains such as the Galapagos Islands a good place to observe the effects of evolution? Mutation rates are higher on island chains Organisms that live on islands tend to reproduce more quickly The relatively rapid geological changes that happen on islands can create distinct environments where different traits are selected for Living things are not capable of traveling from one island to another Cave

Microtaxonomy ( Species and Speciation ) People who do not believe in evolution often cite the classic example of man presumably evolving from the apes. They oftern ask: if humans evolved from apes, why are there apes until today? How will you provide a convincing answer that there is no contradiction in the existence of apes and humans at the same time?
If it is possible asnwer all the following questions, if not, i would like to know about question 2 and question 3. thank you. 1. Why is the statement, humans evolved from monkeys, incorrect? 2. In recent years, strains of bacteria resistant to antibiotics have created serious health care challenges for our society. Based on what you've learned about natural selection, explain how the overuse of antibiotics could influence the evolution of bacterial diseases. 3. How does the peppered moth example demonstrate that evolution is directional? 4. Is is viable to believe both in creation and evolution
Question 14 Saving. Organismo may not be perfectly adapted to their environments for which of the following reasons: Physical constraints that cannot be overcome. Because natural selection cannot anticipate future conditions, adaptati on lags at least one generation behi nd any environmental changes that occur. The same trait may face contradictory selection pressures (e.g., large/sexy fins vs small/fast fins) There may not be any geneti c variation available for evolution of certain traits that woul d provide a fitness advantage if they were present. All of the above.

QUESTION 3 What is the role of fossils in supporting the theory of evolution? There have been many fossils of intermediate types discovered that provide strong support for the theory of evolution There are not enough fossils to support this theory Fossils of dinosaurs show that other types of life existed, but there is no evidence of relationships between them There are plenty of fossils to show that animals have evolved, but there are not enough fossils of human ancestors to suggest that humans are related to other animals
Question 2 The definition of natural selection includes: the inability of poorly adapted individuals to produce offspring. the adoption of the physical characteristics of the parent by their offspring. O the cloning of individuals to produce exact copies. O the ability of some individuals who are better adapted to their environment to produce more offspring than poorer adapted individuals. O resulting in the extinction of the selected organisms. Question 3 Let's assume that you have been working out at the gym every day for months until you are completely buffed out with well defined muscles. Which evolutionary biologist from Darwin's century would claim that your children would be born in a buffed out condition? Hutton O Leclerc Darwin O Lyell O Lamarck

Can you please help me with this question The theory of evolution was controversial when it was first proposed in 1859, yet within 20 years virtually every working biologist had accepted evolution as the explanation for the diversity of life. Explain in at least 50 words why.
