Evidence for Evolution

Based on the picture above, The oldest fossil would be found in layer

• F

• B

• C

• D

Based on the photo above, You could assume that

• Wings were developed before shells

• Shells evolved before Wings

• Plants were the first to evolve

• Organisms were first found on land

A fossil of an extinct dinosaur is found and the anatomy of the fossil shows similarities to that of a bird. What could this mean?

• This is purely by chance and isn't significant
• All dinosaurs evolved into birds and that's why there aren't any dinosaurs alive today
• The extinct dinosaur and modern bird share a common ancestor
• Dinosaurs choose to fly, and evolved into birds to escape predation and capture food

What is suggested by the similarity of early embryos of different species of vertebrates?

• no evolutionary relationships between the groups
• recent common ancestry
• similar environments in the past
• evolution from a distant common ancestor

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

• natural selection
• embryology
• speciation
• evolution

There are Penguins found on the tip of Africa and In Antarctica- very different continents. You could assume that the penguins

• Travel from Continent to continent and Interbreed
• through natural selection, developed similar traits to adapt to their environment
• chose to change their appearance to evade predators more easily
• Compete for the same food source

Having remnants of leg bones in Whales supports the idea of

• Vestigial Structures
• Homologous Structures
• Analogous Structures
• Common ancestry

Bats and Butterflies having wings supports the idea of

• Analogous Structures
• Homologous structures
• Vestigial structures
• Common Ancestry

All of the following species share the same bones in roughly the same position. This is an example of

• Analogous structures
• Vestigial Structures
• Homologous Structures
• Embryology

Based on the picture, what organism is closest in relation to the Human?

• Yeast
• Bullfrog
• Cow
• Fruit fly
