Evolution Review #1 (15q)

In order for new species to develop, there must be a change in the

• temperature of the environment

• migration patterns within a population

• genetic makeup of a population

• rate of succession in the environment

Which statement is not part of the concept of natural selection?

• Individuals that possess the most favorable variations will have the best chance of reproducing.

• Variation occurs among individuals in a population

• More individuals are produced than will survive.

• Genes of an individual adapt to a changing environment.

Which statement about the species is correct?

• Species A, B, C, and D came from different ancestors.

• Species C evolved from species B.

• Species A, B, and C can interbreed successfully.

• Species A became extinct

Which occurrence represents an example of evolution?

• Exposure to radiation reduces the rate of mutation in leaf cells.

• A mutation in a liver cell causes a person to produce an enzyme that is less efficient.

• Cells in a zygote eventually change into bone cells or skin cells.

• Some antibiotics are almost useless, because pathogens have developed a resistance to these antibiotics.

Which statement is most closely related to the modern theory of evolution?

• Characteristics that are acquired during life are passed to offspring by sexual reproduction.

• Evolution is the result of mutations and recombination, only.

• Organisms best adapted to a changed environment are more likely to reproduce and pass their genes to offspring.

• Asexual reproduction increases the survival of species

The theory of biological evolution includes which concepts?

• species of organisms found on Earth today have adaptations not always found in earlier species

• fossils are the remains of present-day species and were all formed at the same time

• individuals may acquire physical characteristics after birth and pass these acquired characteristics on to their offspring.

• the smallest organisms are always eliminated by the larger organisms within the ecosystem

Which statement represents the major concept of the biological theory of evolution?

• A new species moves into a habitat when another species becomes extinct.

• Every period of time in Earth's history has its own group of organisms.

• Present-day organisms on Earth developed from earlier, distinctly different organisms.

• Every location on Earth's surface has its own unique group of organisms

Which is an example of evolution?

• development of the modern horse from earlier horse species

• development of muscle tissue from embryonic mesoderm

• replacement of a lost claw of a lobster

• germination of a 100-year-old spore when moistened

Many animals have developed courtship behaviors. Males will often dance, swim, or sing in a particular way to attract a female. Males who are more successful at the courtship behavior will have a greater chance of having more offspring. This behavior is a result of

• natural selection

• genetic engineering

• asexual reproduction

• gene manipulation

Which statement is not part of the concept of natural selection?

• Individuals that possess the most favorable variations will have the best chance of reproducing.

• Variation occurs among individuals in a population

• More individuals are produced than will survive.

• Genes of an individual adapt to a changing environment.
