|
One such line of evidence is the observation that many species have similar physical characteristics.
|
|

Three main lines of evidence support the scientific explanation that all evolved from a common ancestor:
|
anatomical similarities, embryonic development, and vestigial structures
|
|
|
Anatomical similarities:
|
Many organisms have similar anatomical features such as limbs.
|
|
|
Embryonic development:
|
Some features become apparent as an embryo develops.
|
|
