Clouds affect the amount of solar energy by blocking some of the light that reaches earth.
There's a shrink to the upward thrust of a sand dune. they do no longer stay interior a similar place yet crawl downwind and are replaced by capacity of latest ones. at last, they attain the factor the place they'd be stabilized by capacity of plant existence. Barrier islands are formed a similar way, different than by capacity of water, somewhat than wind.
Answer:
20 million years
Explanation:
If we have a neutral mutation rate of one mutation per 5 million years, then the total of eight mutation between the two different species would be 20 million years. This is because both species will have 4 mutations in those 20 million years, so combined, both by 4, will have 8 mutations between them. So few mutations on so much time will result in two species that are very similar to each other even after 20 million years of evolution, even making them hardly distinguishable, especially if it comes to defining fossil records from them both. A nice example of this are the members of the felidae (cat) family, which are all very closely related, and are almost identical, thus making it extremely hard to distinguish two species of the same or similar size by their fossils.
Yes this is true sort of like when light rays pass through water particles in the atmosphere and create a rainbow :)
