Natural Selection


See the source image


Living things have slowly evolved and adapted to changes in the natural world. Evolution is the process through which species change over time. The basis for the theory of evolution came from observation by Charles Darwin. Darwin proposed that evolution could be explained through a process he called natural selection.

You and a team of biologist are exploring nature to explain how species have been able to adapted and change in their natural environment.  Your teams job is to gather information about how evolution works through the process of natural selection.  You will visit websites to help you understand the terminology used, how natural selection works and how this fits into the theory of evolution. You will document your findings in a Powerpoint or Prezi.


Vocabulary to look for:

evolved,  finches, peppered moths, variation, mutation, adaption, offspring

natural selection, sexual reproduction, asexual reproduction, extinction

successive generations


4 things to consider about natural selection:

Variation in trait

Heritable variation

Struggle for existence outgrow resources

Differential reproduction









Step 1: Gather a team of 3 biologist. The team should click all hyperlink and website to gather information and answer discussions about evolution and natural selection.

 Guided Question for comic strip

  1. When it comes to crickets, what does fitness mean?
  2. Is calling good or bad for a cricket's fitness?
  3. Give some examples of selection at work in this cricket story.
  4. How does selection favor calling? How does selection favor not calling?

Step 2: Compare answers , discoveries and findings with group members and bringing putting information together to on  How natural selection works and how this fits into the theory of evolution.

Step 3: Combine all team members information into a well organized and informative presentation. Using the rubric to follow project guidelines.

Congratulations Biologists you have uncovered the mystery of species evolution and adaption in the natural environment!

Use what you have learned about natural selection to play "Who Wants to Live A Million Years" The goal of this game is to make the necessary changes to your species so that it can live 1 million years.
