the name of the ship Charles Darwin went to the Galápagos Islands on 

the Beagle

100
The survival and reproduction of the organisms that are genetically best fit for their environment
What is the definition of Natural Selection?
100

List the 3 types of adaptation

Behavioural, Psychological, Structural 

100

The strongest evidence for evolution 

What are fossils? 

100

Described as the number of reproductively viable offspring that an organism produces in the next generation.

2 components of Lamark's theory; explain them!

1. acquired characteristics 

2. use/disuse

200
The variety of dog and cat breeds that we have today are a product of _________ _____________.
What is Artificial Breeding (Selective Breeding)
200

A harmless species imitates a harmful species

What is Mimicry?

200
An example of a structure that is homologous to a cat’s paw.
What is a Dog’s paw, human arm, bat wing, whale flipper
200

What exerted selective pressure in the Staphylococcus aureus case study?

antibiotic

300

Explain the fossil distribution in rock strata

Newer strata: near the top, resemble modern creatures

Older strata: near the bottom, different from known creatures

300

Name 2 reasons why scientists would perform artificial selection

Nutritional value, yield, drought resistance, appearance

300

A genetic advantage of one organism over another

Selective advantage

300
Body parts that share a common function but have a different structure
What is an analogous structure?
300

Environmental conditions that select for certain characteristics of individuals, and select against other characteristics. 

An organism survives long enough to reproduce.

400

What are transitional fossils?

show intermediary links between groups of prehistoric organisms and help scientists better understand relationships between groups of organisms alive at different times.

400

Natural Selection can only occur when this is involved

What is Genetic Variety?

400

The venom of the black mamba snake is an example of this type of adaptation

What is an example of Physiological Adaptation?

400

What type of structure are the hip bones of a dolphin?

What are Vestigial Structures?

400

Mutations can only be inherited by offspring when they occur in this cell type. 

Gamete

500

What does descent with modification mean?

All life descended from some unknown organism (common ancestor).

500

Explain why Natural Selection ISN'T Directional

It is situational, it is not the result of an intended purpose. It is a response to the situation/environment exerting selective pressure on organisms.

500

What is the difference between variation and an adaptation. 

Variation just refers to the different traits expressed by members of the same species. 

Adaptation: those traits that confer a selective advantage in a given environment. 

500

What conclusion do we draw in embryology when the the embryos of various species are  similar to each other

They share a common ancestor?

500

Why is there variation between members of the same species (2 ideas)?

Meiosis: each gamete inherits a unique combination of alleles.
