Natural Selection and Adaptation Review
Question | Answer |
---|---|
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 are 3 examples of fossils? | Bones buried in the earth, Footprints in the mud, Imprint of an organism in a rock |
There are 5 species of lizards in a rain forest. A new predator moves into the rain forest with the lizards. What could a beneficial adaptation of lizard species 1 have to survive? | Changing color, camouflage speed. |
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 |
