Question

drag the words into the correct boxes

1. the gradual change in a population over time is
2. are favorable variations which give an organism an advantage for survival and increase the individuals fitness.
3. is the book published by darwin which explains his theory of natural selection and descent with modification.
4. is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. this is the accepted mechanism for evolution.
5. the more offspring an organism has, the more \fit\ that organism is in their environment.
6. in order for a trait to be selected by nature, it must be (able to passed from parents to offspring) and there must be (different forms) of that trait.
7. increase genetic variation
8. traits which offer benefits or greater fitness will increase in over time within a population.
9. two populations of mice lived in a beach community. the environment was mostly made up of sand and a few grasses. most of population a had tan hair with a few black haired mice. population b were mostly black haired mice. which population is most fit in the beach environment? and. according to darwins theory of evolution, the black - haired trait will over time.

adaptations
b
natural selection

on the origin of the species
mutations
frequency
evolution
a
variations

Explanation:

1. Evolution is the gradual change in a population over time.
2. Adaptations are favorable variations that give an organism an advantage for survival and increase individual fitness.
3. "On the Origin of the Species" is Darwin's book explaining natural - selection and descent with modification.
4. Natural selection is the process where well - adapted organisms survive and produce more offspring.
5. More offspring mean higher fitness in an environment.
6. For a trait to be selected, it must be heritable and have variations.
7. Mutations increase genetic variation.
8. Traits with benefits will increase in frequency over time.
9. In a sandy beach environment, tan - haired mice (Population A) are more fit. The black - haired trait in this environment will decrease over time according to Darwin's theory.

Answer:

1. evolution
2. adaptations
3. On the Origin of the Species
4. natural selection
5. (No answer needed as it's a statement)
6. heritable; variations
7. mutations
8. frequency
9. Population A; decrease
