Evolution

Extinction of a species is most likely to NOT occur in which example?

• the organism is larger and stronger than others in it’s environment
• the organism is smaller and smarter than others in it’s environment
• the organism is able to survive and reproduce more than others in it’s environment
• the organism is larger and smarter than others in it’s environment

A layer of marine fossils is discovered in a desert environment.  Which hypothesis best explains the discovery?

• the area was once covered by water
• volcanic activity once occurred in the area
• a catastrophic event once occurred in the area
• Erosion turned most of the limestone into sand

Analyze the picture of various animal limbs.  What type of structure is shown that provides evidence for the adaptation of organisms?

• Internal Structures
• Homologous Structures
• Heterogenous Structures
• Analogous Structures

Species acquire many of their unique characteristics through

• Homeostasis
• Variation
• Pangaea
• Homologous Structures

Fossils of warm-weather plants were found on an island in the Arctic Ocean.  What can best be concluded from this discovery?

• Spores of plants drifted by air currents to the island
• Ocean currents carried the plants to the island
• The island drifted from the tropical region to its present location
• Seeds of plants have been carried by migratory birds.

Genetic diversity amongst members of a species is also known as:

• adaptation
• variation
• law of evolution
• phenotype

Adjustment to environmental conditions is known as

• Adaptation
• Evolution
• Natural Selection
• Darwinism

Similarity in embryological development among vertebrate species indicates what?

• common ancestry
• convergent evolution
• adaptation of interiors
• most species that have ever lived are now extinct

Given equivalent adaptations that developed independently, such as eyes or flight, these are what type of structure?

• Internal Structures
• Homologous Structures
• Heterogenous Structures
• Analogous Structures

A species is best defined as:

• a population that frequently interbreeds
• a community of diverse species
• a group of individuals that normally only breed among themselves
• the top predators in an ecosystem
