Question

What discovery would weaken the primordial soup hypothesis of the origin of life?

Answer 1

Answer:

Option 4.

Explanation:

Primordial soup hypothesis explains that the early life has been originated in the ocean. The idea of primordial soup was first stated by Oparin and Haldane.

The early earth's atmosphere contains large amount of water, carbon dioxide, warm ocean and traces of various gases.Thunder, lightning ans asteroid impact is common in the early earth's atmosphere.  . Thus, uncommon asteroid impact weakens the hypothesis of primordial soup.

Thus, the correct answer is option 4.

Answer 2

Answer:

Asteroid impacts were uncommon when life presumed to have happened

Explanation:

The primordial soup hypothesis is based upon the impact that the asteroids had on Earth and the development of life on it. The hypothesis suggests that the asteroids were carrying the basic ingredients for life to develop, so they ''seeded'' the earth with life. Also, this hypothesis suggests that there were constant bombarding by asteroids, so they brought in lot of organic material with them. If it is proven wrong that there were lot of asteroids falling on Earth at the period when life is presumed to have begun, but instead that they were very few, this hypothesis will easily be dismissed. The reason why it will easily be dismissed is that it will lose the base around it is formed, and without it, it will have nothing as its basis.
