Have you ever considered how the gradual change from one creature to another (see above for standard theory as it exists today) – Darwinian Evolution. can explain metamorphosis? Take for example, the well known stages of a butterfly (wings and everything – an entirely distinct creature from its hungry caterpillar code carrying, sluggy creature). Would they record the caterpillar as a distinct creature from the butterfly in the fossil record? I know – they would say that soft-bodied creatures don’t survive well in the fossil record! Ummm, maybe that is why we don’t have those transitional forms. Could early evolution be via metamorphosis? Could epigenetic processes that can radically and rapidly rearrange a complete creature in its developmental stage, be applied to earlier (developmental) stages of evolution itself?
Did you ever look in wonder at your jam jar of frog spawn and gasp in delight when they transformed miraculously into swimming tadpoles and finally watch as they suddenly sprouted little buds that became legs (I suppose fish would sprout little fins based upon the same basic blueprint). Then an amazing thing happens, the fish stay in the seas and rivers and low and behold, the little amphibian walks unto land. In fact, it would drown (imagine that) if it cannot make it out of its pond. That’s an incentive if ever I heard one to get some of Mother Nature’s creatures onto land. Of course, the land was already colonised by lush plants and lots of scrummy insects to eat. and walk onto land? Well, I was thinking,
if you apply the same principal to early evolution – such as transition from swimming amoebas (code carriers), because it is the code that can completely transform one body plan to another and it could be as simple as hormones released that trigger those miraculous transitions, we might have an alternative explanation of how evolution might have occured. And according to recent studies, from jelly fish to complex animals, that METAMORPHOSIS can be triggered by a simple hormone. For instance, “How does one genome create two completely different body plans in one animal?” Science Daily asks. The article below notes that in Current Biology, German scientists described a new hormone responsible for metamorphosis in jellyfish and linked it to a common developmental biology pathway found in more complex animals.
