AP Evolution- Evidence and Natural selection

Inherited trait that helps an organism survive is a(n) __________.

• Fossil
• Adaptation
• Ancestor
• Natural selection

Structures with the same parts have different functions; suggests that organisms share a common ancestry

• vestigial structures
• homologous structures
• adaptive radiation
• fossil

The ability of an organism to survive and reproduce in its specific environment 

• diversity.
• evolution
• adaptation
•  fitness

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

In natural selection, the selective agent is the

• humans
• mutations
• breeders
• environment

which of the following describes natural selection

• it acts on genetic material directly

• it acts on existing phenotypes

• it forms new traits

• it forms new genetic material

Evolutionary Similarities that can be seen in organisms by comparing their DNA is called-

• Biochemical Similarities
• Embryology
• Vestigial Structures
• Homologous Structures

Some organisms have genes that improve their ability to survive and reproduce. If the gene also help their offspring survive and reproduce, then which of the following will most likely increase?

• The number of genes in a species
• The frequency of genes in a population
• The frequency of genes in one individual 

The table shows the survival rate of two types of beetles in the same environment over a period of three years.  

Which statement about the beetles in this environment is best supported by the data?

• Brown beetles have a shorter life cycle than green beetles have
• Green beetles are more fit for their environment than brown beetles
•  brown beetles are undergo more unfavorable mutations than green beetles

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
