The origin of life and evolution

It is considered that the most primitive cells were formed when:

• Some protocells were able to move, reproduce and interact with others.

• Some protocells were able to carry out cellular respiration and reproduce.

• Some protocells were able to exchange matter and energy with the exterior, adapting to environmental changes and producing replicas of themselves.

• Some protocells were able to produce different replicas of themselves and breathe.

According to endosymbiotic theory, the nucleus of eukaryotic cells:

• Came about due to the DNA coiling and the edges hardening for protection.

• Was formed by folding of the membrane of a prokaryotic cell.

• Was formed by a different mechanism to the above three.

• Was another aerobic prokaryotic cell which was swallowed and lived in symbiosis with the first.

That organisms have an internal drive, meaning they tend towards improvement and complexity, is a postulate of:

• Darwinism.

• Lamarckism.

• Saltationism.

• Actu

Which of the following contributed most to the development of Darwin's theory?

• Which of the following contributed most to the development of Darwin's theory?

• The ideas of the evolutionist A.R. Wallace, his trip around the world, and his knowledge of actualism and Lamarck's theory.

• His knowledge of actualism and artificial selection, his trip around the world, and the ideas of the evolutionist A.R. Wallace.

• His trip around the world, the ideas of Thomas Malthus, and his knowledge of artificial selection and actualism.

Which evolutionary theory first indicated that similar organisms are related and descend from a common ancestor?

• Synthetic theory or neo-Darwinism.

• Darwin's theory.

• This premise does not belong to any evolutionary theory.

• Lamarck's theory.

What could Darwin not explain?

• The origin of variability among individuals in a population.

• Why best-adapted individuals leave more offspring.

• Why natural selection favours best-adapted individuals.

• None of the above.

The accumulation of heritable changes experienced by organisms and populations to adapt to variations in the environment and survive is known as:

• None of the above.

• Speciation.

• Biodiversity.

• Adaptation.

Knowledge of which genetic processes made significant contributions to Darwinism?

• None of the above.

• Genetic recombination and mutation.

• Natural selection and crossbreeding.

• Crossovers and mutations.

The marine iguana of the Galapagos Islands is:

• Biogeographic evidence of evolution.

• Paleontological evidence of evolution.

• An isolated case of adaptation that has no connection to evolution.

• Physiological proof of evolution.

Among other adaptations, hominids have:

• A large brain and robust teeth.

• Teeth small and a large brain.

• Strong teeth and a similar brain to other vertebrates.

• Relatively small teeth and brain.
