Evolution introduction - year 10

Where the better adapted organisms survive to pass traits along to offspring.

• Evolution
• Natural Selection
• Extinction
• Artifical Selection

What is the advantage of having different shaped beaks?

• To look different from other species.
• To be able to eat the food readily available in the environment.
• To protect itself against predators.
• To protect itself against prey.

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.

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

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

Body part you have that use to have a purpose but now has little or no function

• vestigial organ

• embryology

• homologous structures

Scientist that contributed the most to our understanding of evolution

• Darwin

• Lamarck

Organisms with the best suited adaptations for their environment are more likely to survive and reproduce than organisms that are not very well adapted

• natural selection

• artificial selection

• creationism

a trait that gives an organism an advantage in their particular environment

• overproduction

• adaptation

• selection

• variation

The cave fish and minnow are related to each other but the cave fish is blind and only has the remnants of an eye. What type of structure is this?

• vestigial

• analogous
