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.

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
