Evidence of Evolution 2

Which statement is part of Darwin’s theory of evolution by natural selection? 

• More offspring are produced than can possibly survive.
• The organisms that are the fittest are always largest and strongest. 
• The number of offspring is not related to fitness.
• Acquired characteristics that are inherited are the cause of evolution.

What type of beak would help a bird pick insects off a plant?

• a large thick beak
• a long thin beak
• a small short beak

Study of embryos of various organisms to show a common ancestor because of similarities in development

• natural selection
• embryology
• speciation
• evolution

The arm of a human, the flipper of a whale, and the wing of a bat all have similar bone structures. Therefore, these parts of the body would all be considered...

• homologous structures

• vestigial structures

• transitional fossils

• common ancestors

Archaeopteryx is a fossil that displays a mix of characteristics belonging to both birds and dinosaurs. This makes Archaeopteryx an example of a...

Some people can wiggle their ears, even though it no longer serves a purpose. This is a:

• Homologous structure

• Vestigial structure

• Analogous structure

• Weird thing to do on a first date

The legs in the picture are:

• Homologous structures

• Vestigial structures

• Analogous structures

• Funny looking

The hind (back) leg bones in this whale are:

• Homologous

• Vestigial

• Analogous

• Great for walking on the beach

Unborn or unhatched offspring that are still developing:

• Analogous structures

• Embryos

• Vestigial structures

• Fossils

Structures that have the same function but did NOT come from a common ancestor:

• homologous structures

• analogous structures

• vestigial structures

• embryos
