1. Astronomers have made great strides in sending probes out to other planets and moons in our solar system. If they were to find a living creature some place other than Earth, how could DNA analysis help them better understand the organism? Explain in 1–2 sentences.
My answer: DNA analysis can reveal whether the species is related to any other living organism on the planet. And also count the number of mutation between them to figure out whether the species are related.
2. In 1973, biologist Theodosius Dobzhansky wrote an essay titled “Nothing in Biology Makes Sense Except in the Light of Evolution.” Why is evolution so important for understanding biology? Explain your answer in 1–2 sentences.
My answer: Without evolution, there would be no explanation for why the organisms/species have the behavioral, physical, and physiological characteristics or traits that they do.
