EVOLUTIONARY PATTERNS
-
MACROEVOLUTION
large-scale evolutionary changes that occur above the species level, leading to the formation of new species or groups
Focus- speciation, extinction, adaptive radiation
Ex- evolution of whales from terrestrial mammals and Darwin's finches evolving different beak shapes
-
MEGAEVOLUTION
extremely large-scale evolutionary changes that result in the origin of major taxonomic groups , change in kingdom or phyla level
FOCUS- evolution of phylum-level diversity, origin of major morphological innovations
Ex-Cambrian explosion producing most modern phyla and the evolution of vertebrates from invertebrates
-
-
ADAPTIVE RADIATION
rapid evolution of a single ancestral species into variety of species, each adapted to different ecological niche
-
-
MECHANISM
-
-
over time, populations diverge into different species
-
SIGNIFICANCE
-
-
How evolutionary pressures shape morphology, behavior, ecology
