Biology 120 Unit 4.1

What domain did NOT evolve from the universal common ancestor (Tree of Life)?

Natural selection does not require heritable variation to exist in a population.

Stromatolites are...

What included the Triassic, Jurassic, and Cretaceous periods (ages of reptiles)?

Which factor does NOT allow the formation of organic molecules?

What includes 4.6 byo - 542 myo, and featured little biologic activity?

What resulted from serial endosymbiosis?

What theory was Georges Cuvier responsible for?

What occurred 251 million years ago at the end of the Paleozoic era, killing 96% of marine species and 8/27 insect spp.?

What does NOT support the theory of endosymbiosis?

What is the present era?

What caused variation in RNA?

What is the contribution an individual makes to the gene pool of the next generation relative to those of others?

Through his research, Darwin had explained the origin of life.

Where is genetic variation found?

What did Darwin NOT observe on his travels?

Who was responsible for the Scala Naturae theory?

Which causes adaptions to the environment?

Charles Darwin was the first to use the term "evolution," and discovered how species change.

Endosymbiosis occurs when a prokaryote engulfs another & they both benefit, creating a selected against relationship

What ended the Mesozoic period 65 million years ago, killing many families of plants and animals?

Macroevolution is an evolution at the genera, family, order, or above levels, and changes can be seen over generations

Frequency of alleles is the number of alleles in a population.

Charles Lyell was responsible for the theory of uniformitarianism.

Microevolution is a small scale evolution that shows a change in allele frequency in a population over time.

What caused a change in beak length of the 1977 Daphne Major finches?

What was the name of Darwin's ship?

When did the first tetrapods appear?

The Bottleneck Effect is not a random occurrence.

The limitations of natural selection are existing variation, historical constraints, compromise, and environment.

Simple polymers of amino acids and simple polymers of RNA can catalyze reactions.

Jean-Baptiste de Lamarck was responsible for the acceptance of the "Old Earth" theory.

Why were marine fossils found at mountain tops in South America?

How did H2O form on Earth?

When did the Earth begin to cool?

Who developed classes and binomial nomenclature?

How old is the Earth?

The frozen Earth was responsible for the gap between the appearance of simple organisms and major phyla.

What can RNA NOT do?

What species did Darwin NOT observe in his understanding of natural selection?

What branch of science has laws?

What findings contradicted the Scala Naturae and Strict Biblical View theories?

Which of these is NOT a mode of selection?

When did plants and fungi move onto land?

Protocells lack bound vesicles.

What is a theory?

The Founder Effect occurs when founding members of a new population have different allele frequencies than the original.

In what populations is genetic drift strongest?

What did NOT lead to the Oxygen Revolution?

Under which condition is the Hardy-Weinberg Equilibrium true?

What ended the Paleozoic era with a mass extinction and origin of present-day organisms?

What determines what layer of rock comes before another allowing you to date each layer relative to one another

A change in gene frequency cannot occur through genetic drift or gene flow.

James Hutton was responsible for the theory of gradualism.

Protocells are independently formed biologically, and pass on genetic information in the form of well-organized acids

Migration is random, and therefore gene flow (the movement of genes in and out of a population) is random.

Gene pool is the proportion of each allele in the population.

What is the Hardy-Weinberg Equilibrium?

What occurred 542 myo - 488 myo and included the Cambrian Explosion?
