Imagine a field of monkey flowers. Some of them are pink and others are red. It turns out that the pink flowers are pollinated mostly by bumblebees, whereas the red flowers are pollinated mostly by hummingbirds. As a result pink flowers are fertilized mostly by pollen from other pink flowers, and red flowers are fertilized mostly by pollen from other red flowers. The pink and red flowers have become separate species.  What type of speciation is this?  Sympatric speciation type  (my answer) What mechanism of reproductive isolation was involved?

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.
