How does the independent assortment of chromosomes during meiosis contribute to genetic variation?
- It creates new alleles through mutations
- It results in the formation of different gametes
- It causes genetic drift within a population
- It creates new combinations of genes through crossing over

Which of the following is true according to Darwin's theory of evolution?
- All life on Earth is descended from a single common ancestral species
- Evolution is always a slow process of gradual change in which one species turns into another species
- Evolution is a goal-oriented process in which species progressively become more complex and better suited to their environments

Jean-Baptiste Lamarck thought so, but modern evolutionary theory wouldn't agree Evolution describes genetic change over time, and sources of genetic change are all random: Selection is non-random, but not all evolution occurs through selection
Is evolution goal-oriented?
