What can be inferred about these 4 different limbs?

• These organisms are all the same.

• Their similar structures suggest a common ancestry.

• These organisms live in the same enviornment.

• These limbs perform the same functions.

• The brown population would be larger after 10 years.

Populations change due to natural selection.

• TRUE

• FALSE
