Which idea associated with relative dating helped inspire Charles Darwin's work on evolution?
mrs_skeptik [129]

Answer: The idea that the earth is extremely ancient.

Explanation:

Charles Darwin was a British naturalist who worked on the organic evolution of living organisms and in his books outlined how present-day organisms evolved from earlier, different species.

Evolution is an extremely slow process. It is difficult to obtain direct evidence of evolution in action. However, scientist including Charles Darwin, have from many fields gathered a great deal of indirect evidence that supports the theory of evolution. This evidence comes from many sources which include the FOSSIL RECORDS.

The history of life on earth is recorded in fossils (remains of organisms preserved mainly in earth's sedimentary rocks). Scientist can determine the age of rocks in which fossils occurs by using RELATIVE DATING. This method give a geological time scale, showing earth's age ( as measured by dating it's rocks), and tracing the history of life on it.

Therefore the idea that the earth is extremely ancient is associated with relative dating which has helped inspire Charles Darwin's work as an evidence on evolution.

For a project I needed to ask 25 people : do you think eating meat is bad for the environment?
Lelu [443]

Answer:

Yes (It's more inefficient)

Explanation:

in ecology there are things called primary producers (plants) that are eaten by primary consumers (cows and chickens) and then there are humans, secondary consumers, that eat cows and chickens for energy.

The further we move from eating primary producers the more inefficient we become in consuming energy. Meaning, it requires a lot more natural energy consumption to support a human that lives on meat only as compared to a human that eats plants only. this inefficiency only magnifies when communities practice unsustainable food methods.

There are sustainable ways to eat meat, but (at least in the US) our current conventions of meat production are unsustainable and environmentally destructive.
