Evolution

An adaptation is a characteristic, useful
for organisms to survive and reproduce
Adaptable traits passing through generations
Scientists use fossils to track all these changes

Accumulation of inherited changes…
(Evolution, evolution)
…that happen over time in populations.
Evolution, evolution

Similar body parts occurring across species
may indicate that they have common ancestry
Species often share similar adaptations
Changes that benefit both their populations

Accumulation of beneficial changes
Evolution, evolution
Adaptable traits passed through generations
Evolution, evolution
Accumulation of inherited changes
Evolution, evolution

They say species with similar DNA must be
closer relatives on the evolutionary tree
Remnants of structures that were once maybe useful
Scientists say these structures are vestigial

Accumulation of inherited changes
Evolution, evolution
Adaptable traits and vestigial structures
Evolution, evolution
Accumulation of beneficial changes
Evolution, evolution
…that happen over time in populations
Evolution, evolution
Accumulation of inherited changes
Evolution, evolution
