Evolution 1
The process in which a species has changed over time is known as this.
What is evolution?
A variation that makes an organism better suited to its environment
What is an adaptation?
The Island where Charles Darwin explored...
Galapagos
Scientist who study the past by collecting and examining fossils.
What is a paleontologist?
He is known as the father of evolution and used finches on the Galapagos Islands to develop his theory.
Charles Darwin?
A group of organisms that share similar characteristics and can reproduce among themselves is?
What is a species.
The study of how embryos develop similarly.
What is an embryoloy?
Comparing the amount of radioactive element with the amount of non-radioactive element to estimate how old a fossil is.
What is radiometric dating?
Preserved remains of ancient organisms
What are fossils?
Darwin noticed the changes in what of the finches when studying them?
Their beak types
The concept that organisms who are the best suited to their environment will be the most successful
What is survival of the fittest?
A group of mammals that include monkeys, apes, & humans that share similar characteristics.
What are primates.
An inherited trait that makes an individual different from other members of its species
What is a variation?
Type of rock formed when sand, silt, clay, or mud are compacted and cemented together or when minerals are deposited from solution.
What is sedimentary
The oldest fossil are found in what rock layers?
What is the bottom layer/deeper layers?
The process of choosing parent organisms for desired characteristics is called
Artifical Selection
Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring?
What is Natural Selection?
Organs/ structures that no longer serve a purpose and have disappeared or reduced in size
Vestigial Organs/Structures
Which statement is true comparing natural selection and artificial selection?
A.) In natural selection, traits benefit humans and in artificial selection, the traits benefit the species
B.) In natural selection, traits benefit the species and in artificial selection, the traits benefit humans
C.) In natural and artificial selection, the process takes hundreds of years to occur
D.) In natural and artificial selection, nature determines what traits will be passed down to offspring.
B.
If the same antibiotic is used too many times, it can become less effective against a certain type of bacteria. This is known as ...
antibiotic resistance
An estimate of how old a fossil is based on the idea that in undisturbed areas, younger rock layers are deposited on top of older rock layers
What is relative dating?
Name one evidence of evolution
homologous structures, embryology, fossils, DNA analysis, vestigial structures, or directly through plants
If individual species continue to inherit helpful variations of a species what will happen?
A new species will develop.
Similar structures that evolved from a common ancestor such as bones humans, cats, bats, and whales have in common.
homogolous structures
When nature selects and species with beneficial adaptation survive and produce offspring
Natural Selection
Crossing a labrador and a poodle to create a labradoodle is an example of?
Artifical Selection
The latest group of ancestors are called?
What are Homosapiens sapiens
