Science 3-1

similar function but different structure (bird, bat, insect wings) These would be similar environment but not evolutionarily connected by genetics

• analogous structure

• homologous structure

• vestigial structure

• common ancestor

same structure but different function (whale fin and human arm) These would be evolutionarily connected by genetics

• analogous structure

• homologous structure

• vestigial structure

• common ancestor

NGSS.MS-LS4-2

a structure that is no longer used or useful (appendix, tailbone)

• analogous structure

• homologous structure

• vestigial structure

• common ancestor

the idea that our common structures and genetic similarities are based on a ancestral relationship (we come from the same family)  

• analogous structure

• homologous structure

• vestigial structure

• common ancestor

How do we group organisms

select 2

• by their structures

• color

• behavior

• feet size

Tags

NGSS.MS-LS4-2

Large bone structures can show

• their structures and behavior

• size of the muscles that are attached to them

• characteristic

• mutations over time

Tags

NGSS.MS-LS1-5

NGSS.MS-LS4-1

Another word for trait

• Stamen

• structure

• behavior

• characteristic

Tags

NGSS.MS-LS4-4

how did we go from ancient penguin to current penguins

• mutations over time

• their structures and behavior

• size of the muscles

• common ancestor

NGSS.MS-LS4-2

Why would we say that modern penguins would have come from past penguins?

• their structures and behavior

• Because they have similarities

• Stamen

• characteristic

NGSS.MS-LS4-2

holes on the underside of leaves that take in CO2 (BUT ALSO GIVE OFF a little WATER, which is not good if you live in the desert)

• Mutations

• Characteristic

• Stamen

• Similarities
