The document discusses various evolutionary concepts, including speciation in shrimp and the development of new plant species through polyploidy. It highlights selective traits in animals like stock-eyed flies and hares influenced by environmental changes, as well as the co-evolution of hummingbirds and flowers. Additionally, it addresses genetic diversity in populations, specifically in relation to malaria resistance among beta globin alleles.

1. Match the event with the most appropriate term. Different species of shrimp evolved on either
side of the Isthmus of Panama. A flowering plant produces a polyploid cell that can self-fertilize
and produce a new species. A fish species persists for millions of years with little change. Long
eye-stalks is a selective trait for male stock-eyed flies by enhancing their sexual attractiveness.
During an ice age, more white-coated hares appeared and less brown-coated hares remained.
Two beta globin chain alleles (the HbA normal allele and the HB S sickle cell anemia allele)
both circulate at high frequencies in subtropical regions where malaria is a threat. A beetle
lineage rapidly diversified into several new species after the development of an adaptation for
feeding on flowering plants. The shape of a hummingbird's bill and the shape of a nectar
providing flower both evolved for an optimal relationship.
