Question

1. what was the one organism darwin studied a lot that helped with his theory of natural selection and evolution? 19. fill in the chart about the different conditions of natural selection. you will be using slides #31 - 35. condition of natural selection description condition 1 condition 2 condition 3 survival of the fittest natural selection: 20.fill in the missing words. → organisms with type answer here (good) genes type answer here and pass on their type answer here. → organisms with type answer here (bad) genes type answer here out.

Explanation:

1. Darwin studied finches on the Galapagos Islands extensively. Their beak - shapes varied based on the food sources available on different islands, which was crucial evidence for natural selection.
2. The conditions of natural selection typically include:

• Condition 1: Variation - There is variation within a population for a particular trait.
• Condition 2: Heritability - The variation is heritable, meaning it can be passed from parents to offspring.
• Condition 3: Differential reproduction - Organisms with certain traits are more likely to survive and reproduce.
• Survival of the Fittest: Organisms that are better adapted to their environment are more likely to survive and pass on their genes.

1. Organisms with favorable (good) genes survive and pass on their traits. Organisms with unfavorable (bad) genes die out.

Answer:

1. Finches

19.
Condition 1: Variation - There is variation in traits within a population.
Condition 2: Heritability - Traits are passed from parents to offspring.
Condition 3: Differential reproduction - Some organisms reproduce more successfully than others.
Survival of the Fittest: Organisms well - adapted to the environment survive and reproduce.
20.
→ Organisms with favorable genes survive and pass on their traits.
→ Organisms with unfavorable genes die out.
