ESSENTIAL IDEA:
The diversity of life has evolved and continues to evolve by natural selection.
ESSENTIAL QUESTIONS:
How does natural selection cause evolution?
Why do members of the same species have such variation in their characteristics?
Do the characteristics of individuals or the average characteristics of populations change due to evolution?
UNDERSTANDINGS / APPLICATIONS / NATURE OF SCIENCE
5.2.U4 Species tend to produce more offspring than the environment can support.
5.2.U1 Natural selection can only occur if there is variation among members of the same species.
5.2.U2 Mutation, meiosis and sexual reproduction cause variation between individuals in a species.
10.3.U1 A gene pool consists of all the genes, and their different alleles, present in an interbreeding population.
5.2.U6 Individuals that reproduce pass on characteristics to their offspring.
5.2.U3 Adaptations are characteristics that make an individual suited to its environment and way of life.
5.2.U5 Individuals that are better adapted tend to survive and produce more offspring while the less well adapted tend to die or produce fewer offspring.
5.2.U7 Natural selection increases the frequency of characteristics that make individuals better adapted and decreases the frequency of other characteristics leading to changes within the species.
10.3.U2 Evolution required that allele frequencies change with time in populations.
10.2.U3 Variations can be discrete or continuous.
