The Natural Selection Game
Author/Source: Gendron, Robert |
|
| Overview: | This is a board game that simulates natural selection. It is suitable for an introductory biology class and for more advanced classes where you could go into more detail on important principles such as the role of variation and mutation. |
| Concepts: | This lesson covers the following concepts:- New heritable traits can result from recombinations of existing genes or from genetic mutations in reproductive cells.
- Mutations are random, but selection is not; selection is dependent on many factors.
- The process by which advantageous traits are maintained and disadvantageous traits are weeded out of a population is known as natural selection.
- Random factors affect the survival of individuals and of populations.
- Natural selection acts on individuals and populations in a nonrandom way.
- The proportion of individuals with advantageous characteristics may increase due to their increased likelihood of surviving and reproducing.
- Speciation is the splitting of one ancestral lineage into two or more descendant lineages.
