Evolution
Change in Species over time
Evolution
"Survival of the Fittest"
environmental changes OR genetic variation OR many offspring OR short life span
Type of food eaten by tree finches
animal food (insects or worms)
Antibiotic resistance
Father of Evolution
Charles Darwin
Island where Darwin went to come up with his theory of natural selection
Galapagos Islands
2 factors that decrease the speed of evolution
Stable (non-changing) environment OR identical genetics OR few offspring OR long life span
Type of finch that eats only worms or insects
Warble Finch
HMS Beagle
Requirement for Evolution caused by limited food, mates, space, etc.
Competition
The 4 requirements of evolution
overproduction, coompetition, variation, natural selection
insects and bacteria
Finch that can coexist with a Small Ground Finch and support your answer.
Large Tree Finch OR Small Tree Finch OR Woodpecker Finch or Warbler finch because they eat different types of food
Trait that gives an organism an advantage and helps them survive, for example - claws, snake venom, porcupine quills
adaptation
Offspring with different genes (traits)
Variation
Individuals _______________ __________________ to their environment will survive and reproduce
best adapted
extinct or extinction

Answers vary - must have good explanation.
Which is an example of natural selection - the variety of dog breeds or the variety of finches?
Variety of Finches
Sources of Variation
Mutation or sexual reproduction or crossing over or gene shuffling
Two types of moths - light wings and dark wings on a dark background. The type that has adaptive value.
Dark wings have adaptive value on dark background.
Give an example of environmental change that could cause evolution
