Here's what I think:
The phases are caused by the Earth's shadow (lit from behind by the sun) casting a piece of the moon into shadow. But because the moon orbits the earth those phases are only experienced the same way on one fixed part of the earth's surface. It's is the earth's changing orbit in space which really makes it seem as though the moon cycles through phases from a fixed position on earth. In other words, on the moon, in an earth day, you would actually cycle through all of the phases. Assuming you were on the earth-facing side, you would experience a strange type of day with the blocked out sun rising and setting behind either the earth or the moon twice a day. You would thus have two 'days' and two 'nights' in an earth day. On the 'dark side' of the moon, you would experience full day all of the time and no phases at all.
But I could be wrong.

According to the geological time scale, the species of reptiles evolved after the first insects evolved.
<u>Explanation:</u>
- Both, the species of reptiles and the species of insects evolved in the same period called the Paleozoic period.
- But out of these two, insects evolved first. There are solid pieces of evidence available to prove that the insects existed way before reptiles did.
- It is found that the species of reptiles, which ultimately feed on insects, were the first to evolve after the insects.
