Theories of Evolution

Who among the scientists proposed that evolution is the result of acquired characteristic?

• Charles Darwin

• Gregor Mendel

• Jean Baptiste de Lamarck

• Thomas Malthus

What is the term for a feature that allows an organism to survive better in its environment?

• adaptation

• homologous structure

• variation

• vestigial structure

What do you call the organisms that breed with each other and produce fertile offspring in the natural environment?

• gene pool

• niche

• population

• species

What happens to the survival and reproduction of individuals that are well adapted to their environment?

• better traits

• fewer mutations

• more offspring

• stronger genes

According to Darwin’s theory of natural selection, What do organisms needed to possess to survive?

• characteristics their parents acquired by use and disuse.

• characteristics that plant and animal breeders’ value.

• the greatest number of offspring.

• variations best suited to environmental conditions.

Which is a major concept included in Lamarck’s theory of evolution?

• Change is the result of survival of the fittest.

• Body structures can change according to the actions of the organism.

• Population size decreases the rate of evolution.

• Artificial selection is the basis of evolution..

Which statement about the members of a population that live long enough to reproduce is consistent with the theory of natural selection?

• They transmit characteristics acquired by use and disuse to their offspring.

• They tend to produce fewer offspring than others in the population.

• They are the ones that are best adapted to survive in their environment.

• They will perpetuate unfavorable changes in the species.

In each generation, the wings of experimental fruit flies were clipped short for fifty generations. The fifty-first generation emerged with normal-length wings. What idea is disprove based on the given observations?

• inheritance of acquired characteristics

• inheritance of natural variations

• natural selection

• survival of the fittest

According to Darwin’s Theory of natural selection, individuals who survive are the ones best adapted to their environment. What is the reason for the survival of species?

• possession of adaptations developed through use

• possession of inherited adaptations that maximize fitness

• lack of competition within the species

• choices made by plants and animal breeders

Which of the following statements does NOT support Charles Darwin Theory of Evolution?

• Darwin observed variation within the finches of the Galapagos Islands.

• Darwin proposed natural selection as the mechanism for species change over time.

• Darwin used DNA evidence to support the process of Natural selection.

• Darwin wrote the book Origin of Species by Natural Selection.
