A species of animal or plant threatened with extinction


Scores

Endangered


What % of species that have lived on Earth are still here?


Scores

.1%; that means many species that have lived on

earth no longer exist


If two organism’s DNA is very similar, you can infer that these two organisms

are….


Scores

…evolutionarily closely related.


A scientist who studies fossils to learn about organisms that lived

long ago.


Paleontologist

Scores


Evolution is…; how is this different from Natural Selection?


The gradual change of a species over time; Natural Selection is the

theory Charles Darwin came up with the explain how Evolution happens.

Scores


A record of the geologic events and life forms in

Earth's history


Geological Time Scale

Scores


The law of superposition states that in horizontal layers of

sedimentary rock, each layer is ______ than the layer above it

and _______ than the layer below it.


Older, younger

Scores


A random genetic change that causes an

offspring to have a different trait than

either of their parents


Mutation

Scores



The process by which individuals that are better

adapted to their environment are more likely to survive and

reproduce than other members of the same species.


Natural Selection

Scores


The struggle between organisms for limited resources necessary for survival (food,

water, shelter, space).


Scores

Competition


Who is famous for proposing the theory of natural selection

and getting all the credit? Who had a similar theory

published at the same time?


Scores

Charles Darwin and his book, “On the Origin of Species”, are credited as proposing the theory of Evolution

occurring by Natural Selection. However, Alfred Wallace published a similar theory at the same time, but it was not as well formed nor

accepted.


Who proposed the theory of acquired traits being the source

of adaptations, like a giraffe stretching his next over time?


Lamarck

Scores


What is the fact of nature that causes the “struggle for

existence”, as Darwin called it, or competition within a species

for resources?


Overproduction of offspring

Scores


When you take an observation and draw a conclusion based on what you’ve learned, what you

have formulated is called an


Scores

Inference (Darwin’s theory of Natural Selection is a complicated

inference based on his observations.)


If a species survives due to an adaption and outlasts the

competition, it still will not evolve unless it….


Reproduces, and passes that adaptation onto its offspring.

Scores


A group of similar organisms that can mate with each other and produce

fertile offspring is a…..


Scores

species


What are the two causes of variation that can eventually create a

new species?


Scores

Random mutations and sexual reproduction


When do scientists determine that 1 species has diverged into

two?


When they can no longer interbreed.

Scores


What was the main observation Darwin made that struck him as fascinating and served as the question he sought to answer

with his theory?


How is there such great variation of species on

Earth?

Scores


What are the 3 possible effects of a mutation? What dictates its effect?


Scores

Beneficial, negative, neutral; the environment


How are geological periods divided on the timeline? According to….


The appearance and disappearance of life forms.

Scores


What were likely the first living things on Earth?


Single-celled organisms, probably bacteria.

Scores


What era are we currently living in?


Cenozoic

Scores


According to the fossil record, how long have living things been

on Earth? Be specific.


3600 million years ago

3.6 billion years ago

3,600,000,000 years ago

Scores


According to the geological time scale, how long ago did Earth come into existence?


4500 million years ago4.5 billion years ago

4,500,000,000 years ago

Scores


Where did Darwin do most of his field work while developing his

theory of Natural Selection? What type of species did he focus on?


The Galapagos islands; finches

Scores


What are the four main pieces of evidence for evolution?


-Geological Time (the vastness of time Earth has been here and changed)

-Fossils

-Rocks

-Evo-Devo (Evolutionary developmental biology ;branch of biology that compares the

development & DNA of different organisms to determine ancestral relationship & how they

evolved.)Scores


What extinct species do scientists hope that they can

use DNA to recreate?


Scores

Mammoth


Based on what we studied this unit, how can we be so complex yet have the same # genes as a chicken and

less than an ear of corn?


Scores

Because it’s not the # of genes you have, it’s the way in which those genes are utilized and turned off and off (how long, amounts, timing..). Also, the fact that we share so many genes supports

the idea of shared ancestry too!


What are 3 things that could cause a species to go extinct?


Environmental changeLoss of food source

DiseasesNewly introduced predators

HUMANS!

Scores


Scores

Earth’s timeline

Final Jeopary Question


List the 6 different eras that make up Earth’s timeline and list something significant that

happened in each era.


Scores

Geologic Name EventEarly Precambrian Earth formed

Late Precambrian First single celled organisms, First multicellular organisms marks end of period

Early Paleozoic Fossils with shells marks beginning

Late Paleozoic Mass extinction marks endEarly land plants, amphibians, insects

Mesozoic Mass extinction marks end-fossils include ammonites, dinosaurs, flowering plants

Cenozoic Series of Ice ages marks end-birds, lg. mammals, early grasses
