Natural Selection and Adaptation Review

QuestionAnswer
What is it called when ALL of the organisms of a species die? Extinction
When organisms are better adapted to their environment they will survive and reproduce more successfully. This is a process called __________? Natural Selection, When organisms are better adapted to their environment they will survive and reproduce more successfully.
What is a mutation? DNA accidentally makes a mistake when making a copy.
If a modern day penguin changed over time to be able to fly millions of years from now, this would be an example of ____________. Evolution. The process in which inherited characteristics within a population change over generations, like new species sometimes arise.
A species’ survival is greater when a species has genetic differences from others of the same species without those traits. Natural Selection
Any genetic difference in a species, usually resulting in a physical difference, not necessarily benefiting or harming a species. Variation, Any genetic difference in a species, usually resulting in a physical difference, not necessarily benefiting or harming a species.
A genetic difference such as neck length, beak shape, or color that benefits and organism and helps it survive Adaptation

What can you tell about birds based on the shape of their beaks? The food they eat depends on the shape of their beaks.
What are 3 types of scientific evidence that scientist have that organisms on Earth have evolved? Carbon dating, Genetic similarities, Homologous structures (same bone, in the same area)
Place the correct variation in the chart to show which environment that trait would be helpful to the species. Snow: Extra layer of fat Ocean: Fins Rain forest: Green camouflage Desert: Ability to burrow
Look at Natural Selection and Adaptation Review slideshow. #7, #9, #14. Also Test Review Doc. I SAID LOOK AT IT!!!!!!
Fossil The trace or remain of an organism that lived long ago most commonly preserved in sedimentary rock.
Phenotype The physical appearance. Basically what you see.
Ghenotype The genetic makeup.
Define Homologous (same bone, in the same area)
Even though a horse and a donkey are different species, they have similar teeth, why? Genetic similarities
