What if all the info is stored in the junk DNA, like the Hard Drive stores the info in a computer, so the bodies that live in marine caves can reverse their evolution towards complexity for that particular habitat because the info is in their junk DNA? You know the scientists can’t demonstrate the existence of our Space-Time Continuum without adding 7 dimensions into the equations, therefore there could be more than 7 dimensions and obviously the model of the Universe is a Top-Down model, not a Bottom-Up one, so go figure. . . I am not saying there is a God, because the one from the Bible or from the ceiling of the Sistine Chapel definitely looks like Zeus, I am talking about One Super Dimension of Space.
Giorgiana1976 does not answer the basic point.. Her summary does not even answer the question.. she's talking about the Cambrian era!
The relationship is that they age as time goes,so therefore when each layer of sand comes then they get fossilized underground!
yes, because of complexity being the quality. So it would be like how well something was or is being preserved over a long period of time.
Scientists from the University of Bath (United States) come up with new evidence, which seem to confirm a new law of evolution: organisms evolve in general to an increasing complexity. Of course, such a law of evolution would seem logical if we accept the premise that life began in simple forms.
As simply as that, in this case it can only be one direction in evolution: towards a higher complexity. However, nothing prevents the bodies to return to a simpler form, once a degree of complexity has been reached. Let us not forget that all bodies which have evolved and survived until today, are complex. Bacteria for example, are simple forms of life, but they have adapted very well in today's complex environment.
Of course, there are no rules without exceptions. An example is bodies living in habitats such as isolated marine caves. They seem to regress in their evolution towards complexity. Another example is some species of parasites.
The fossils of the Cambrian have a high level of complexity, in the layers of Cambrian, fossils being found easily.They are very numerous and very diversified. Cambrian fauna includes representatives of all major groups of invertebrates, that still exists today. Species alive today are easily recognizable, with all their characters, once they are met in the strata in which they were fossilized.
Cambrian strata are exposing a sudden explosion of species. As the Cambrian strata are examined, strata which are known to be the oldest containing fossil, we discover that many marine species have existed at the time, very clearly differentiated from one another. The world of that time was as complex as that of today. Some forms are different from those of today, while others are very similar, and in some cases, even identical. In the latter category are blue algae, sponges and marine worms, for example.
