Caution, I never stated that organisms lack the ability to evolve; organisms do evolve, but not in Darwinian fashion. The fossil record and molecular biology--some would even argue astronomy--support this fact. Organisms do evolve, but only in "variation." This, of course, is dependent of the environment itself (and conditions therein). On the flip side, if the environment undergoes changes too rapidly, organisms--even human beings--will certainly die off. Enlight of "cyclic" global climate change, for example, polar bears have certainly seen better days.
The Cambrian period has nothing to do with meteorites impacting planet Earth. The Cambrian period--also known as the Cambrian "explosion"--dating about 550 million years--reveals all major phyla in full form (even soft-bodied organisms like jelly-fish). Prior to the Cambrian period, all we see are (for the most part) bacteria. The fossil record reveals almost nothing until the Cambrian period--hence the term, Cambrian "explosion." Let me explain.
Pretend you are walking down a football field; you pass the 10, 20, 30 yard line, and all you see are various forms of bacteria. Nothing major, but you keep walking... 40, 50, 60 and so on. When you walk upon the 20 yard line (on the opposite side of the football field), you embark on an explosion of phyla--the basic forms of life--which include mammals and reptiles! All at once!!
Significance?
Well... the Cambrian period turns Darwin's Tree of Life upside down. The Cambrian period shows life forms arising abruptly, not progressively in Darwinian fashion. It is common for "most"--if not all--Darwinists to ignore the Cambrian period (and for good reason).
