Evidence for Evolution

Structures with the same parts have different functions; suggests that organisms share a common ancestry

• vestigial structures
• homologous structures
• adaptive radiation
• fossil

A category of structures that have a similar function, but are structurally different.

• Homologous structures

• Analogous structures

• Vestigial structures

• Common core structures

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

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

• natural selection
• embryology
• speciation
• evolution

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

Which of the following organisms the kingdom animalia are not closely related?

• mouse and hagfish
• mouse and lizard
• mouse and pigeon
• mouse and chimp

Two organisms that are closely related would have

• very similar DNA sequence
• exactly the same DNA sequences
• no proteins in common
• completely different DNA sequence

Which of the following are examples of evidence for evolution?

• Fossils and Cellular Structure
• Biological Structures 
• Genetics/DNA
• All of the Above

What are fossils?

• Are the remains or evidence of once-living organisms

• Is the change over time in populations of related organisms

• A chart that divides Earth’s history into different time units

• Occurs when the last individual organism of a species dies

What is the fossil record?

• Are the remains or evidence of once-living organisms

• Is the change over time in populations of related organisms

• Is made up of all the fossils ever discovered on Earth

• Occurs when the last individual organism of a species dies
