Before the Industrial Revolution (top picture), the bark of the trees was
-BARSIC- [3]
This is an example of evolution through natural selection. The peppered moths started off with a light color scheme when the industrial revolution started, and they had this to blend into the trees. The better the moths could blend in, the less likely they were to be preyed upon. Once the trees changed colors, the light moths were vulnerable. The months that thrived in this change were the darkly colored moths. These moths then bred and spread their dark color pattern to best fit into the new environment.

The molecular clock (based on the molecular clock hypothesis (MCH)) is a technique in molecular evolution that uses fossil constraints and rates of molecular change to deduce the time in geologic history when two species or other taxa diverged. It is used to estimate the time of occurrence of events called speciation or radiation. The molecular data used for such calculations is usually nucleotide sequences for DNA or amino acid sequences for proteins. It is sometimes called a gene clock or evolutionary clock.

If the lithosphere is resting on the asthenosphere and you put a lot of
statuscvo [17]

Answer:

Explanation:

Can you think of a solid that can flow?

You use one twice a day! Toothpaste is a solid that can flow. Is the asthenosphere made of toothpaste? Only if the

toothpaste is ultramafic in composition, and then it would only be able to flow if it were really, really hot. Still the

toothpaste analogy gives you a good image of how the asthenosphere might behave if you squeezed it!

Lithosphere

The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid

solid. The lithosphere is the outermost mechanical layer, which behaves as a brittle, rigid solid. The lithosphere is

about 100 kilometers thick. How are crust and lithosphere different from each other?
