What is natural selection?

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

What is evolution?

a gradual change of species overtime

What is a species?

a group of similar organisms that can mate with each other and create fertile offspring

How does natural selection lead to the evolution of species?

when animals are better adapted, they will thrive and reproduce more, making the species bigger

Who is Charles Darwin?

a british naturalist that sailed on the beagle to go observe animals in the galapagos islands

What is a naturalist?

a person who studies the natural world

What is the ship Darwin sailed on called?

the beagle

Where did Darwin travel to make his most brilliant discovery?

the galapagos islands

What is the scientific theory?

a well tested concept that explains a wide range of observations

What did Darwin want to find out in the Galapagos?

understanding the different adaptations on animals

What was Darwin's reasoning on the Galapagos Islands?

plants or animals that arrived on the galapagos islands faced conditions from which were different from those on the mainland- species gradually changed from generation

What is Darwin's theory of evolution?

That animals change overtime and all originated form the finch

What did Darwin examine in his laboratory when he got back to England?

the differences between the animals

Why do the same species of animals that live in the same environment have different traits?

1 surroundings
2 eat different things
3 differnet adaptions
4 different parents

What happened when you put the dams in with the rabbits on the evolution readiness activity?

some rabbits died out bc they lost what they need to survive

What does variation mean?

differences between organisms of the same species

How does variation occur from generation to generation?

every animal is different, therefore the parents create different animals

What is selective breeding?

mixing 2 species to create a certain trait

How does certain DNA change an animal?

certain traits in offspring
different parents

What is special about animals living on different Galapagos Islands?

animals of the same species had different traits than the same species varying from island to island

What triggered Darwin's scientific theory?

animals of the same species had different traits than the same species varying from island to island

Why were animals of the same species different from each other o the galapagos?

adaptions

why does evolution by natural selection becoming more common in a population over many generations?

their is a slight change in every generation building up overtime and changing the species

Why to animals over produce?

not all the offspring will survive

Why does evolution by natural selection take many generations to form?

their is only 1 slight change passed down the generations

What book does Darwin describe natural selection in?

The Orgin of Species

Why does evolution by natural selection result on population level change?

over production

What year and month did Darwin set sail on his voyage?

december 1931

What is the Beagles full name?

The HMS Beagle

How long was the voyage on the Beagle?

5 years

What did Darwin observe on the voyage?

plants and animals

What were 3 observations that Darwin made on the voyage of the beagle?

1 diversity of living things
2 fossils
3 characteristics of organisms

How are the claws of the galpagos and south american iguanas adaptations?

food and survival

How did Darwin explain why Galapagos species had different adaptations form similar south american species?

claw sizes

How does selective breeding support Darwin's hypothesis?

2 different species will create traits that will produce more of that trait

How do variation and natural selection work together to cause evolution?

adapting overtime

What is a fossil?

animal remains or traces from something that lived in the past

How did the beaks of the Galapagos finches differ from island to island?

size and shape

What happens to some animal variations overtime?

the gradually disapear

What did Darwin help us understand?

life on earth

Why are species different?

different food, adaptions, body plans and variation
