Evolution & Classification

The similarities of the bones in the diagram provide evidence that---

• The organisms shown lived in the same natural envionrment
• The organisms shown may have developed from a common ancestor
• The organisms shown have the same genetic diseases
• All vertebrate species have identical forelimbs

The study of the early stages of development that is one evidence of evolution is:

• Homologous Structures
• Embryology
• Vestigial Organs

The opossum and kangaroo both incubate their young in a pouch. This provides evidence that they---

• are descended from a common ancestor
• Have very similar skeletal structures
• belong to the same species
• must range great distances to eat

A trait that an organism expresses during its lifetime will only cause its species to become better adapted if the trait—

• A.  Results from isolation of the organism from the rest of the population 
• A.  Is caused by the genetic code that is present in the gametes of the organism
• A.  Causes a change in the environment surrounding the organism
• A.  Decreases the number of genes in the body cells of the organism

A graph regarding the effect of agricultural bioengineering on insect pests is shown below How has natural selection affected species of insect pests?

• A.  Natural selection has not affected the number of species that are resistant to pesticides
• A.  Natural selection has rapidly increased the number of species that are resistant to pesticides
• A.  Natural selection has only affected the number of species that are resistant to pesticides

The green frog (Lithobates clamitans clamitans) is found in many parts of the United States. The table contains some information about this frog.
Why does the ability to lay 1,000 to 5,000 eggs increase the fitness of the species L. clamitans clamitans?

• A.  It increases the probability that some offspring will survive long enough to reproduce.
• It increases the chance of the recombination of alleles, leading to genetic drift in the population.
• A.  It increases opportunities for offspring to compete for limited resources.
