What is a Vestigial Structure?
Structures that have a common function and suggest common ancestry
The traits of organisms that result from sharing a common ancestor: such traits often have similar embryological origins
A genetically determined structures or attributes that have apparently lost most or all of their ancestral function in a given species
If an organism has a vestigial structure, that structure likely once had a function in a(n)
close relative
early ancestor
unrelated organism
embryological stage
which of the following is an example of a vestigial structure?
the wings of a red-tailed hawk
the hind limbs of a house cat
the fins of sharks
the wings of an ostrich
What is an example of a vestigial structure of a whale?
The solar system
Tail bone
The Pelvis and the Femur
Batman (could be...you never know..)
What is one inference that someone could make from this image?
That Red One
The bone highlighted red was the favorable trait.
They all could fly
Why is studying the embryos of organisms important (in evolution)?
provides evidence that two very different animals could have descended from a common ancestor
It is not important because they grow up differently
What is an example of a vestigial structure of a HUMAN? Select all that apply.
