Natural Selection (survival of the fittest) How does Evolution work?
STUDY
PLAY
Variation
individuals in a population vary from one another
Gene
blue print/ instructions to build a body structure and it is passed from parents to offspring
Mutation
Is a change to a gene
can be a positive/ negative/ neutral mutation
Selection
some variants reproduce more than others
environment
determines which variation/ mutation is positive (+)
positive mutation
survives and reproduces
Inheritance
Parents pass on their traits to their offspring genetically
example:
Survival of the dropper- winners (most nectar collected) became parents and passed the mutation to the offspring
Bunny Survival Game- brown bunny pass down traits to offspring which is brown
Time
successful variation accumulate over many generation
Evolution
the change in the population over time where one trait (adaptation) becomes more common
example:
Fish n' Chips- red color becomes more advantageous in the red lake environment
Adaptation
is a structure that becomes common in a population due to natural selection, because it provides improved function.
