Who worked with flinches to develop his theory?

Charles Darwin

What is speciation?

The formation of new species due to the accumulation of mutations

What is it called when 2 species are evolving side by side?

Co-evolution

What were Darwin’s two main points of Evolution and what did the two points mean?

1. Natural Selection • Some living thing are more suitable or

better for survival

2. Descent with Modification• An organism slowly accumulates

mutation over million of years1. 2.

What is it called when the genes are available to the population?

Gene Pool

What is the difference between gradualism and punctuated equilibrium?

Gradualism • the slow accumulation of mutation over time

Punctuated equilibrium• When organisms stay stable for long periods of time. • Then, there is a short amount of time while there is a major

change when organisms mutate

• Then, they stay in that phase for a long time once again.

Who observed the amount of time that affected mountains, rivers, landforms and masses?

Charles Lyell

Who observed that people produce many children, but we don’t use all our natural resources?

Thomas Malthus

Who wrote up his findings and sent them to Darwin only to find they both had very similar observations?

Alfred Wallace

What are the remains of an animal that no longer in existence?

FOSSILS

What is the chronological “story” showing the life of animals, plants, humans?

FOSSIL RECORD

If you no longer exist and your type has died out, what are you?

EXTINCT

A structure that looks the same but does different things?

Homologous Structures

A structure that looks different but does the same thing?

Analogous Structures

What is a structure that an organism once used but no longer uses?

Vestigial Structures

Natural and expected differences in a population?

Variation

Natural Selection

VS.

Artificial Selection

Natural selection

• Where the organisms survive or don’t survive based on survival of the fittest

Artificial Selection

• Where it permits organisms to live even though they would not have if left up to nature and visa versa

What is pesticides and antibiotics?

Antibiotic overuse will cause things such as medications to not work in the future because organisms adapt to them called natural variation

Pesticides work in a similar way, farmers use them on crops

What are the different types of isolation and what do they do?

Geographic Isolation

• Where the location is difficult to breed

Reproductive Isolation

• Where two individual are not on the same reproductive cycle such as skunks

Behavioral Isolation

• Where a physical action that either separates or keeps the females from being interested in the males such as the cranes’ dance

What are the types of evolution?

Divergent Evolution

• 2 or more organism that started out together on a similar path but later on they go into different paths

Convergent Evolution

• Organisms start at different point but they come together with similar features million of years later.

Parallel Evolution

• 2 or more organisms evolve along a specific pathway but don’t share a common ancestor

What will I get from doing something

vs.

What will happen to me if I get caught

Cost- benefit analysis

What is it called when there is a change in the gene pool from generation to generation?

Genetic Drift

What are the types of selection?

Stabilizing Selection • Get rid of extremes and chooses the average

Directional Selection• An extreme favors over other extreme

Disruptive Selection • Favors both extremes at the same time

What gas did not exist in the world until the first organism on Earth did what?

Oxygen did not exist in the world until the anaerobic (did not breath oxygen) gave off the oxygen as by-products.

Therefore, oxygen became a part of the atmosphere after million of years

What is a adaptive radiation?

Nature hates an area void of life such as a vacuum. Therefore, if there is the possibility of life, there will be life.

What hypothesis developed how organism evolved from simple to more complex organism?

Endosymbiotic Theory

Who used water vapor, volcanic gases combined with electricity to create amino acids?

Miller and Urey

What is it called when the results of a natural disaster limits the gene pool and the organisms that survive are the “founders” of the next generation?

Genetic Bottleneck and

The Founder Effect
