Question

"we basically know nothing about how life on Earth originated from 3.5 billion years ago" assume that one of your friends said this and you remember learning something different in your bio 21 class. how would you respond using scientific evidence?

To fully answer this question, you need to put the four-stage hypothesis into context (I.e what it is trying to explain,be specific) And give an explanation of each stage including any relevant experimental evidence (or deductive reasoning) that supports the stage

Answer 1

The Earth formed roughly 4.54.54, point, 5 billion years ago, and life probably began between 3.53.53, point, 5 and 3.93.93, point, 9 billion years ago.The Oparin-Haldane hypothesis suggests that life arose gradually from inorganic molecules, with “building blocks” like amino acids forming first and then combining to make complex polymers.The Miller-Urey experiment provided the first evidence that organic molecules needed for life could be formed from inorganic components.Some scientists support the RNA world hypothesis, which suggests that the first life was self-replicating RNA. Others favor the metabolism-first hypothesis, placing metabolic networks before DNA or RNA.Simple organic compounds might have come to early Earth on meteorites.

Hypotheses of origins

1 Stage 1: Abiotic Synthesis of organic Monomers-The abiotic (nonliving) synthesis of small organic molecules, such as amino acid and nucleotide monomers.

Stage 2: Abiotic Synthesis of Polymers-The Joining of these small molecules into macromolecules, including proteins and nucleic acids.

Stage 3: Formation of pre-cells-The packaging of all these molecules into pre-cells, droplets with membranes that maintained an internal chemistry different from the surroundings.

Stage 4: Origin of Self- Replicating Molecules-The origin of self- replicating molecules that eventually made inheritance possible.
