Evolution

• Homologous structures have different functions but the same ancestor
• Analagous structures have the same function but different ancestors
• Allopatric speciation occurs due to the presence of a barrier
• Sympatric speciation occurs without a barrier due to genetic changes
• Aposematic coloration means bright colors to warn predators about poison
• Batesian mimicry occurs when a non-harmful species mimics a harmful species
• Mullerian mimicry occurs when two poisonous species resemble each other
• A clade includes an ancestor and all its descendants
• Largest to smallest taxonomic classification:

  Domain Kingdom Phylum Class Order Family Genus Species
• Adaptive radiation is when an ancestor diversifies into multiple distinct lineages
• Book lungs are found in arthropeda
• Frogs undergo meroblastic cleavage
