Embryo• Embryo is an
organism in its early stage of development.
Pharyngeal Pouches
• Pharyngeal pouches is an area located in the back of the mouth or throat

• Vertebrate animals that have a backbone and similar organ structures.

Embryology provides evidence of evolution example #1
Larva
Adult barnacleAdult crab
identical larvae, different adult body forms
Embryology provides evidence of evolution example #2
similar embryos, diverse organisms
Evidence of Evolution in Agriculture• Evolution of pesticide
resistance in response to selection.
• Pesticides eliminate all insects except those with genes causing resistance
• Resistant genes of survivors are passed on to next generation forcing species evolution.
