Natural Selection

The change over time in populations of related species.

• biological evolution
• transition
• variation
• adaptation

NGSS.MS-LS4-2

These cause variations.

• mutations
• adaptations
• a desire to change
• injuries

Tags

NGSS.MS-LS3-1

NGSS.MS-LS4-4

A slight difference in an inherited trait between individual members of the same species.

• variations
• adapatations
• homologous structures
• analogous structures

Tags

NGSS.MS-LS4-4

An inherited trait that increases an organism's chance of surviving and reproducing.

• variation
• adaptation
• vestigial structure
• mutation

Tags

NGSS.MS-LS4-4

The discovery of DNA and genes proved that

• Darwin was wrong
• mutations create variations and come from genes
• we are all the same species
• bats and butterflies have a very close common ancestor

Tags

NGSS.MS-LS3-1

The study of the similarity and differences in body structures between species.

• comparative anatomy
• embryology
• molecular biology
• archaeology

Tags

NGSS.MS-LS4-2

Body parts of organisms that are the same in structure and position but different in function.

• embryos
• homologous structures
• analogous structures
• vestigial structures

Tags

NGSS.MS-LS4-2

Body parts that function like each other, but are different in structure.

• embryos
• homologous structures
• analogous structures
• vestigial structures

Tags

NGSS.MS-LS4-2

Body parts that have lost their original function.

• embryos
• homologous structures
• analogous structures
• vestigial structures

Tags

NGSS.MS-LS4-2

Organisms with these structures are believed to be closely related.

• analogous structures
• homologous structures 
• mutated DNA
• gills
