Natural Selection
100
This is the name of the ship Charles Darwin sailed in on his voyage to the Galapagos Islands
What is the HMS Beagle
100
This is a group if organisms that are able mate and produce fertile offspring
What is a species
100
These variations helped Larkeys in the prairie survive
What is long legs and solid or striped fur.
100
These are similar structures that related species have inherited from a common ancestor
What are homologous structures
100
These four things lead to natural selection
What is overproduction, variation, competition, and selection
200
What was Charles Darwin's job on his voyage
What is a naturalist; to study the plants, animals, and geologic structures they encountered
200
A trait that helps an organism survive and reproduce
What is an adaptation
200
This was the selective pressure on the Larkeys
What are predators.
200
These are preserved remains or trances of an organism; such as teeth, bones, shells, or footprints
What is a fossil
200
The process by which organisms that are better suited to their environment are more likely to survive and reproduce is ...
What is Natural Selection
300
This was the name of the book that Darwin published after his travels
What is The Origin of Species
300
this is a well-tested concept that explains a wide range of observations
What is a scientific theory
300
Forest Larkeys have a higher survival rate if they have these adaptations.
What is short legs and spotted or solid fur.
300
This is the term used to describe the formation of a new species
What is speciation
300
What was the selective pressure for the population of finches on the Galapagos Islands?
What is the amount of water Dry=Large seeds Wet= small seeds
400
These adaptations help the marine iguanas on the Galapagos survive with little food on land available.
What are large claws for climbing and swimming, bacteria in their gut to digest algae, dark skin to warm up in the sun.
400
This is gradual change over time
What is evolution
400
This is why certain larkeys are able survive in the prairie while others die.
What is that some larkeys have traits that are favorable in the prairie environment while others do not. Not all organisms are affected equally by selective pressures.
400
Insects and birds both have wings. These types of evidence might show whether or not insects and birds are closely related.
What are body structures and DNA and protein structures.
400
Humans taking traits that are desirable and selectively breeding organisms for these traits such as labradoodles are an example of this
What is artificial breeding/selection
500
After seeing that the organisms on the Galapagos Islands resembled mainland organisms with slight difference Darwin concluded this.
What is that island species had become different from their mainland relatives over time.
500
These are slight changes or differences between organisms of the same species
What are variations
500
Over time you would expect the population of forest larkeys to change. What traits would you see more often and why?
You would expect to see more short legs and spotted and solid fur. This is because the traits that are unfavorable cause the larkey to die and are not passed on, while traits that are favorable help the larkey survive and get passed on more often.
500
The wings of a bat, legs of a dog, and fins of a fish are all examples of this.
What are homologous structures.
500
In natural selection this is what is putting the pressure on organisms
What is the environment.
