Which of these can result in a population looking more similar over time and can be described as selection against both extremes of a trait?
A population of squirrels lived together in a forest. An event occurred that caused the population to diverge into two different species over a long period of time. Which of these is most likely the event that occurred?
In a bird population, 50% of the individuals had white feathers, and 50% had colored feathers. Over time, it was observed that 98% of the population had colorful feathers. The rest had white feathers. How did the type of selection in this example affect the population’s biodiversity?
Two insect groups vary genetically by two genes. When put together, they were able to reproduce and produce offspring that could also breed. Which best describes this insect population?
A population of chimpanzees was separated when the forest that they lived in had a section cut down and a town was built. After a long period of time, the chimpanzees came back into contact but were incapable of breeding. Which best describes the process that occurred?
Which of these is the definition for speciation ?
Which organisms are most likely to survive in a population in which disruptive selection is occurring?
Which process drives Darwin’s theory of evolution?
A population contains short plants and tall plants. The short plants are not able to compete with tall plants for sunlight. The tall plants, however, are more susceptible to wind damage. Which type of selection will this population of plants most likely experience?
Which graph represents selection that may lead to reduced variation in a population?
