Question

1. bob believes that giraffes have long necks because they have stretched their necks to try and reach food that is high in trees. since the parent had stretched its neck, it passed the long neck on to its offspring.

ryan believes that giraffes have long necks because the ones with long necks were able to reach the food, and those with short necks could not and died. the long necked giraffes reproduced, and soon all of the giraffes had long necks.
a. who thinks like lamarck? ________________________
b. who thinks like darwin? ________________________
c. who disproved the idea of inheritance of acquired traits using tail - less mice? ________________________

Explanation:

• a. Lamarck's theory emphasizes that organisms can pass on traits acquired during their lifetime. Bob's idea that giraffes' long necks (acquired by stretching) are passed to offspring aligns with Lamarck's view.
• b. Darwin's theory is based on natural selection. Ryan's belief that long - necked giraffes survived (due to access to food) and reproduced, while short - necked ones died, is in line with Darwin's natural selection concept.
• c. August Weismann conducted experiments with tail - less mice. He cut off the tails of mice for multiple generations, and the offspring still had tails. This disproved the inheritance of acquired traits.

Answer:

a. Bob
b. Ryan
c. August Weismann
