While webbed feet were evolving in ancestral ducks, with each generation: Most ducks had about the same amount of wobbing on their feet as their parents. See Answer Which of the following is REQUIRED for the process of evolution by natural selection to occur? If so, why did we evolve this way? (b) How does competition among humans differ from the competition in other animal species? For example, when humans first migrated to North America, they were faced with a new environment with different plants and animals. Finches with small beaks ate all of the small seeds, leaving only bigger seeds. Traits must be inherited from one generation to the next. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Why didn't other animals evolve to become closer to humans in intelligence? In this sense, a species is the biggest gene pool possible under natural conditions.

How do modern biology, evolution, and natural selection explain why there are differences in innate aptitude in animals (such as there are humans who are smarter than others, some are more artistic than others, etc.)? Their feet are webbed and this trait makes them fast swimmers. There is no definitive answer to this question, but there are some interesting theories that can be considered. From one ancestral species that colonized the remote island chain, many new finch species evolved with differently sized and shaped beaks to exploit the foods available. Horned lizards use their horns to defend against predatory birds. Why would competition between two animals of the same species likely be more intense than competition between two animals of different species? Similarities at the beginning of embryonic development imply they have common ancestors. How do you capture a snapshot of evolution as its happening? I will post some .
