Through epigenetic alterations, our genomes retain something like a memory of the environmental signals received during the lifetimes of our parents, grandparents, great-grandparents, and perhaps even more distant ancestors.

Grandfathers who lived their preteen years during times of plenty were more likely to have grandsons with diabetes—an ailment that doubled the grandsons' risk of early death.

According to a recent field called epigenetics, there is a third factor also in play, one that in some cases serves as a bridge between the environment and our genes, and in others operates on its own to shape who we are.

A person's height, for example, is often estimated at 0.8, meaning that 80 percent of the differences in height among individuals in a specific population are due to differences in their genetic makeups.

Humans and chimpanzees share up to 99% of the same DNA, which is particularly remarkable considering we don't look anything like each other. The reason behind our vast difference in appearance is all thanks to our seemingly useless so-called "junk" DNA

the ancient human effective population size 1.2 million years ago, the number who could breed--was about 18,500, and couldn't have been larger than 26,000.
About 8 percent of human genetic material comes from a virus and not from our ancestors
the structure of nuclear components—chromosomes, RNA, protein complexes and other small bodies—could be as biologically important as the components themselves.
We each have two parents, but their genetic contributions to what makes us us are uneven. New research shows we are an amalgam of influences from Mom and Dad : Scientific American
-
genes from Mom and Dad do not always exert the same level of influence on the developing fetus
-
imprinted genes

To explain the origin of life, scientists seek to explain the origin of its components. The three most important of these are RNA, DNA, and proteins. (The Loom | Discover Magazine)
"Synthetic biology is a field devoted to creating better tools for biological engineering, which could be used to create new biological systems. This Cribsheet summarizes the basics of biotechnology and explains how to assemble and program strands of DNA. It also charts the progress of synthetic biology toward a future of cheap, powerful, easy-to-use biotechnology tools that may be difficult to regulate or control." (Seed)

"In this video introduction, Perspective author John Mattick, Stephen Buratowski, and Science editor Guy Riddihough discuss the new and increasing understanding of how RNA regulates DNA, and how RNA may have been the original molecule of life. " 319 (5871): 1781b -- Science
Carl Zimmer's Dissection: "But scientists don't quite know why a network like the one in E. coli can handle this rewiring so well. The source of their strength lies not in a single molecule -- DNA -- but in a complicated web of relationships. The network itself is the mystery for biologists in the 21st century."
