• a trace of an organisms that existed in the past

In natural selection, the selective agent is the

• humans
• mutations
• breeders
• environment

What is the process in which humans breed organisms for certain traits?

• natural selection
• inheritance
• artificial selection
• descent withOUT modification

Darwin wrote that organisms with traits that are best suited to the environment will ________________

• increase in number
  
• become extinct
  

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures
• analogous structures
• homologous structures
• fossil structures

The gradual change in species over time is...

• Evolution
• Nucleotide 
• Adaptation
• Natural Selection

What is the study of organisms at the early stages of development?
