Bio1Q#4:evidence evolution(fossil,embryo,anatomy,DNA) 2019

_____________ are built the same but may have different functions, like a bat wing and a whale flipper. 

• arms
• vestigial structures
•  homologous structures
• adaptations

These are homologous structures because they ____________ but ______________. 

•  are built the same  ; have different functions
• have the same function ; are built differently 

Humans, birds, whales, and lizards all have similar arm bones. What is the reason for this?

• The function of these bones is the same in all animals
• They live in similar environments
• They have a common ancestor
• All organisms resemble humans
