Define evolution as change in heritable characteristics and explain how inherited variation and selection alter populations over generations.
Explain how the process of evolution occurs.
| a | evolution is cumulative change in population/species over time OR change in allele frequency |
| b | a population has variations amongst the individuals |
| c | due to meiosis OR sexual reproduction |
| d | due to mutations |
| e | certain variations give an advantage to some organisms over others in certain environments |
| f | populations/species produce more offspring than the environment can support |
| g | individuals of the species compete for the same resources |
| h | the better-adapted organisms tend to survive and reproduce OR less adapted organisms tend to die or reproduce fewer offspring |
| i | individuals that reproduce pass on their heritable characteristics/alleles/genes to their offspring |
| j | natural selection increases the frequency of heritable characteristics/alleles/genes of the better-adapted organisms |
| k | specific example described |
