Evolution

Charles Darwin came up with this theory 

• Natural Selection
• Mutation

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

• increase in number
  
• become extinct
  

Another word for adapt is ____________.

• change
• create

Which of the following is NOT an example of natural selection? 

• People selectively breeding hamsters.
• Insect populations developing resistance to certain pesticides.
• Bacteria becoming resistant to antibiotics.
• Male birds of certain species developing colorful feathers to attract female mates.

Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring? 

• Evolution 
• Variation 
• Adaptation
• Natural Selection 

Which of the following is a fossil?

• a plant that has recently died
• a group of organisms that can reproduce
• a structure or organ that no longer functions
• a trace of an organisms that existed in the past

In natural selection, the selective agent is the

• humans
• mutations
• breeders
• environment

Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population

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
