Evolution 1
The process in which a species has changed over time is known as this.
What is evolution?
The ability of an individual to survive and reproduce is known as this.
What is fitness?
Two types of fossil dating
relative and absolute dating
The oldest fossil are found in the
Bottom layer
Similar structures that evolved from a common ancestor such as bones humans, cats, bats, and whales have in common.
Homologous Structures
A scientist who studies fossils
Paleontologist
Any inherited trait that increases an organism's chance of survival is known as this.
What is an adaptation?
Finding fossils in different rock layers in the same place allows us to do this
What is relative dating?
A record of Earth changing over a long period of time
What is fossil record?
Preserved remains of ancient organisms
What are fossils?
This term refers to different traits and alleles within a population.
What is variation?
The concept that organisms who are the best suited to their environment will be the most successful
What is survival of the fittest?
This type of vestigial structure is found in our digestive system. This organ used to be used to digest cellulose for our ancient ancestors.
appendix
Similarities between the bone structures of paws, hooves, wings, and fins are examples of this.
What are homologous structures?
What characteristic did Darwin observe about the finches on the Galapagos Islands?
Their beaks!
The concept of humans selecting desired traits in species.
What is Selective Breeding?
Structures that have no apparent function and appear to be residual parts from a past ancestor
Vestigial Structures
Why did the population of moths change?
question vary...Need to mention industrial revolution, smoke, trees turning black, the mutated black moths were able to survive and reproduce better and their population grew.
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?
Natural Selection
The concept that members of each species compete regularly for food, space, and other necessities is known as this.
What is struggle to survive?
What are the 4 steps of Natural Selection in order!
1.Overproduction
2. Genetic Variation
3. Struggle to Survive
4. Successful Reproduction
Many of Darwin's major discoveries happened in this location.
What is The Galapagos Islands?
When an organism completely dies out, it is called.....
Extinction
Fossil form in this type of rock
sedimentary rock
A mistake or change that occurs in the DNA sequence is called a ______________________.
mutation
Shows evolutionary relationships among groups
What is Cladogram?
Charles Darwin's journey on this ship sailed him across the world to the Galapagos Island.
