Naturally Selected to Survive

What is the term used to describe the process by which species with favorable traits survive and reproduce, passing those traits to the next generations?

• Genetic mutation

• Natural selection

• Environmental adaptation

• Species evolution

According to the text, what might be one of the many reasons behind the recent global warming we have experienced?

• The earth cooling down after an ice age

• The natural cycle of the earth warming up after ice ages

• The development of air pollution by species

• The process of genetic mutation in organisms

What does adaptation refer to in the context of species surviving in changing environments?

• The ability to move to different locations

• The process of inheriting traits that enable survival and reproduction

• The change in the earth's temperature and precipitation

• The extinction of species that cannot adapt

What can happen to organisms of a species that do not adapt to changes in their environment?

• They may develop new favorable traits

• They may become the dominant species

• They risk dying out

• They will definitely cause global warming

What color were the light gray peppered moths camouflaged against?

• Dark-colored trees

• Gray-colored trees

• Black-colored trees

• White-colored trees

Why did the dark-colored peppered moths become more visible during the Industrial Revolution?

• Because of the decrease in the number of trees

• Because of the increase in the number of predators

• Because the trees began to blacken with soot

• Because the moths changed their color

What was the main reason for the change in moth population according to the text?

• The introduction of new machinery

• The moths' natural migration patterns

• Predators eating a lot of the light gray peppered moths

• The moths evolving into a new species

Which theory does the example of the peppered moths' evolution support?

• Lamarck's theory of evolution

• The Big Bang Theory

• Charles Darwin's theory of natural selection

• Mendelian genetics

Who published a report about the moths a few years after Darwin's death?

• Charles Darwin

• J.W. Tutt

• The scientists who noticed the moth population change

• The factory owners

How does the concept of 'survival of the fittest' relate to natural selection?

• It describes the ability of organisms to physically outmatch their competitors

• It refers to the survival and reproduction of organisms best adapted to their environment

• It is about the fastest organisms escaping predators

• It focuses on the largest organisms dominating smaller ones
