Diet! - Ever hear the expression, "You are what you eat" ???
|For Meme Lovers Only|
Seriously, you people new this all along. You know the advantages of a healthy well balance diet as opposed to an unhealthy diet. You know the effects of having abundance as compared to the extreme circumstances of starvation. All of these are environmental cues which trigger variying epigenetic responses within the genes of different people. This is why the role of Gut Bacteria is so important, because what you take in your body by choice in the way of nutirtion can effect how your cut bacteria react, which also triggers signaling messages into your body's genome. These same rules apply to all the other lifeforms on the Earth as well. For example, when I wrote recently about a fungal species I use in forumations for plant root inoculations. While our nutrition intake is an internal one, plants on the other hadn have an external one which we could compare the symbiosis of beneficial fungi and bacteria which externally colonize the rootsystem, can be compared to our internal gut bacteria. Trichoderma was a subject I wrote about where the fungi not only processes nutrients, but also provides specific signaling messages to a plant's immune system to step up production.

Toxic Pollution effects epigenetic gene expression - so think Endocrine Disruption & Nylonase - then we can dump the doctrine of
Random Mutation(otherwise known as copying errors which result in bad or lucky mistakes) and Natural Selection(otherwise known as Tinker Bell) is a mysterious intelligent animist type of god which is omnipotent, omnipresent and if you believe the latest literature out there, also omniscient. [I'm not kidding either folks. For all the talk of ridding mankind of their various beliefs in gods, the secular elements of our modern world are obsessed with creating their own version of gods in their image]

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Seriously now, what more could I add to the list of environmental cue factors that trigger epigentic responses to gene expression ? How about hervivores, predators, nightime, daytime, caves, volcanoes, toxins, pollution, disasters (natural & human caused), wars, climate change etc, etc, etc.
Well, this wasn't so bad. Lots of Memes and Photographs with very little text! Environmental cues are everywhere and they influence how the informational content of genes are expressed. Survival, reproduction, health (good or bad), climate adaptability, all manner of ecosystem niches, etc, etc, etc.
|A little Natural Selection humor here|
BTW, just as a reminder of what natural selection is and isn't, retired Geneticist, Wolf-Ekkehard Lönnig, from the Max Planck Institute for Plant Breeding Research in Germany has a nice page on the history of the definition of "Natural Selection", it's problems and attempts at finding a more viable alternative for the outdated terminology in view of latest modern scientific discoveries.
