From ScienceDaily:

Dr. Hollie Putnam, a National Science Foundation Ocean Sciences Post-Doctoral Fellow, is researching the mechanisms that corals use to respond to altered ocean conditions. Her work in the Hawai’i Institute of Marine Biology at the University of Hawai’i at Manoa is revealing that some coral are responding to climate change by changing markings on their DNA to modify what the DNA produces. Like punctuation marks in an alphabet, this changes the result (proteins made) without altering the original letters (the DNA). Although this is a known phenomenon in many organisms, how coral use this to their advantage is largely a mystery.

The cauliflower coral, which was vulnerable to acidification, showed an increase in DNA methylation. This ability to regulate what the DNA produces may be a mechanism by which this species responds to environmental perturbations. While it might appear that this tactic of modifying DNA markers leads to environmental susceptibility, Putnam explains that the process is much more complex. More.

We bet it is.

    Now, if I could only get the corals in my tank not to die off with small changes in pH.

    The point is IS DNA changing without processes like evolution?? is it innately changing albeit by a different process.?

    But the DNA isn’t changing.

    Absolutely correct, Ginger. This is a new low in deception from the Left.

    The vast majority of the DNA in every cell of the body is suppressed. What an underhanded way to promote the religion of pantheism – the evolutionary cosmology.

    How the DNA is expressed is changing.
    Therefore evolution is very much involved.
