DNA evidence supports that all life is descended from an original species from ancient times/common ancestor. It is as probably all organic beings which have ever lived on this earth have descended from some one primordial life form. There is grandeur in this view of life that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved.
Although, there are mutations which mainly caused by the changes of DNA. Mutations are unavoidable and occur at a random rate. It’s occurring in random rate because of the faulty internal DNA processes or environment. Complex creatures evolve from more simplistic ancestors naturally over time & they never stop…
Darwin imagined it might be possible that all life is descended from an original species from ancient times…
Although the fossil record provides evidence that evolution occurred, the record is incomplete. All organism share DNA. DNA collects both backwards & forwards. As DNA is a double helix molecule, every strand of the DNA zipper is the complement of the other. Transcription of DNA proceeds both way backwards and forwards.
Transcription factors may be tens or thousands of base-pairs away from the gene that they control, and even on different chromosomes.
Scientists discover that DNA cannot be endlessly mutable, as neo-Darwinists assume & most mutations are deleterious, so mutations in such a complex structure would quickly destroy many functions at once.
Coding segments (genes that coded for proteins) were a minor component of the total amount of DNA in each cell. It was embarrassing to find that we have only about as many genes as mice (about 25,000) which constitute only about 3% of our entire genome. The remaining 97% was of largely unknown function (probably the ‘junk’ DNA). But at about 93% of the genome is transcribed because of much energy and coordination. is required for transcription. So, the whole genome is used by the cell and there is no such thing as ‘junk DNA’
ATP (ATP: Adenosine tri-phosphate, ATP is a nucleotide with three phosphate groups instead of one phosphate group. The point of cellular respiration is to harvest chemical energy from food and store it in the chemical bonds of ATP. In this diagram Nitrogen=blue, Phosphorus=yellow, Carbon = grey, Oxygen = red. Hydrogen atoms are not shown),
