• evolution

• overproduction

• natural selection

NGSS.MS-LS4-1

NGSS.MS-LS4-2

the mechanism of evolution in which individuals that are better adapted are more likely to survive and reproduce to pass down their beneficial genes & traits

• variation

• overproduction

• evolution

• natural selection

Tags

NGSS.MS-LS4-4

random changes in DNA that leads to new traits that will be passed on IF beneficial to an organism's survival

• mutations

• variation

• natural selection

• overproduction

NGSS.MS-LS3-1

NGSS.MS-LS4-4

a scientific explanation that has been tested and supported by evidence

(hint: __________ of evolution)

• theory

• adaptation

• evolution

• idea

Tags

NGSS.HS-LS4-1

NGSS.HS-LS4-2

an inherited trait that increases an organism's change for survival

• mutation

• adaptation

• evolution

• overproduction

Tags

NGSS.MS-LS4-4

the adaptation that allows organisms to resemble (blend into) the surrounding environment, a defense mechanism used by many organisms

• mimicry

• camouflage

• variation

• evolution

the environment selects traits that help individuals survive and reproduce and the genes for those traits are passed on to the next generation

• overproduction

• natural selection

• mutation

• migration

• Charles Darwin

• Jean Baptiste Lamarck

• Aristotle

• Chales Lyell
