Document Summary
Adaptive radiation is a fairly rapid mode of speciation. Kicked off by competitive release (new environment, mass. Angiosperms are very diverse due to wide variety of speciation opportunities given by physical characteristics as well as temporal qualities that determine which animals pollinate them. Plants are immobile so this is ideal for plant. * two or more species competing for limited resource. * coexisting species in an area will compete for resource (overlapping cheetah/lion range compete for food resources) ( animals competing for water) * each party is worse off due to presence of other species. Plants compete for space, water, soil nutrients, for sunlight, become tall to grow and obtain light energy) * disease causing organisms (parasites/pathogens benefit at the expense of host individual) ^^ any of these types of relationships can give rise to an . Evolutionary arms race reaction to adaptation of first species.
