Evidence of Evoltuion

Which two organisms have hair? 

• Sharks & Ray Finned Fish
• Primates & Rodents
• Birds & Crocodiles
• Rabbits & Birds

According to this cladogram, sharks are MOST closely related to which organism? 

• Amphibians
• Ray finned fish
• Crocodiles
• Birds

According to this cladogram, birds are LEAST related to: 

• Amphibians
• Sharks
• Ray Finned Fish
• Crocodiles

What do scientists use to organize all the information they find to determine evolutionary relationships?

• Cladogram

• DNA

• Chart

• Family Tree

What are the 4 pieces of evidence scientists use to determine if organisms share a common ancestor?

• DNA, analogous structures, fossils

• Embryos, visible characteristics, DNA, fossils

• DNA, Embryos, Homologous structures, fossils

• Shared derived characteristics, homologous structures, DNA

What can help you decide where an organism goes on a cladogram?

• All the organisms
• Number of shared derived characteristics
• DNA
• Pictures of the organisms

What shared derived characteristics do amphibians and ray-finned fish have in common?

• eggs with shells and amniotic egg
• bony skeleton and vertebrae
• none
• four limbs, bony skeleton, and vertebrae

This picture is an example of

• Cladogram
• Homologous structures
• Matching bones
• Similarities 

When a lineage splits on a cladogram what is happening?

• Extinction
• Speciation
• Mating

Similarities in embryonic development probably suggest that

• the organisms mated together
• the organisms share a common ancestor 
• we all share the exact same genes
