What is the most important for origin of life?

So the correct option is ‘ Carbon’.

What is a Darwinian approach?

Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual’s ability to compete, survive, and reproduce.

What does artificial selection show about population?

The process of domestication is called artificial selection. Like natural selection, artificial selection acts by allowing differential reproductive success to individuals with different genetically determined traits in order to increase the frequency of desirable traits in the population.

When did man first appear on Earth?

seven million years ago

Is artificial selection directed by humans?

Introduction. Artificial selection in livestock is primarily driven by human intervention in mate selection. Animal breeding essentially began with the first livestock domestication events approximately 10,000 years before the present (MacHugh et al., 2017).

What are the theories on the origin of life?

Life began at deep-sea vents The deep-sea vent theory suggests that life may have begun at submarine hydrothermal vents spewing key hydrogen-rich molecules. Their rocky nooks could then have concentrated these molecules together and provided mineral catalysts for critical reactions.

Who does the selecting in artificial selection?

Farmers and breeders allowed only the plants and animals with desirable characteristics to reproduce, causing the evolution of farm stock. This process is called artificial selection because people (instead of nature) select which organisms get to reproduce.

What is the best theory that explains the origin of life?

RNA World has been the prevailing theory for the origin of life since the 1980s. The emergence of a self-replicating catalytic molecule accounts for signature capabilities of living systems, but it doesn’t explain how the protobiological molecule itself arose.

What is artificial selection Meaning?

Selective breeding of organisms to produce domesticated animals with more desirable traits; selective breeding to test for genetic variation and covariation in a population. Compare to natural selection.
