Within a population of sunflowers, a new individual has a novel dominant mutation that causes it to flower 4 months earlier than the rest of the population. That sunflower survives and successfully self-fertilizes, leading over time to a novel population that evolves larger leaves and smaller flowers. This new population does not interbreed with the original population, although they are found in the same areas. This is an example of O Allopolyploid speciation O Behavioral isolation O Allopatric speciation O Sympatric speciation O Adaptive radiation

Evolutionary lineages

An evolutionary lineage is a series of populations of organisms that descend from a common ancestor. Each species in the lineage is the direct consequence of evolutionary change from a common ancestor. A phylogenetic tree is generally used to display lineages visually. Lineages are components of the phylogenetic tree of life. Molecular systematics procedures are widely used to predict lineages.
