That human behavior is more influenced by things outside of us than inside. The 'situation' is the external environment. The inner environment is genes, moral history, religious training.
An Internet meme is a hijacking of the original idea. Instead of mutating by random change and spreading by a form of Darwinian selection, Internet memes are altered deliberately by human creativity. There is no attempt at accuracy of copying, as with genes - and as with memes in their original version.
My parents couldn't give me a whole lot of financial support, but they gave me good genes. My dad is a handsome son-of-a-gun, and my mom is beautiful. And I've definitely been the lucky recipient. So, thank you, Mom and Dad.
No matter how civilized we are and how much society has curbed violent behavior. Human beings still have the same genes they had 10,000 years ago. Our bodies are designed to have a certain amount of physical stress and violence in them. We're designed to run from jaguars and fight to defend our territory.
New molecular methods that add or modify genes can protect plants from diseases and pests and improve crops in ways that are both more environmentally benign and beyond the capability of older methods.
RNA interference has proven to be a quite reliable mechanism for turning genes off in a whole variety of different plants and animals.
Man is a competitive creature, and the seeds of conflict are built deep into our genes. We fought each other on the savannah and only survived against great odds by organising ourselves into groups which would have had a common purpose, giving morale and fortitude.
Looking out over the port of Dover, with the endless steam of boats coming in and out, every British citizen is reminded that belonging here has never been about blood or genes. It's simply about being at home on this discrete island and being aware of the privileges and responsibilities that brings.
Animals have genes for altruism, and those genes have been selected in the evolution of many creatures because of the advantage they confer for the continuing survival of the species.
If someone's liver doesn't work, we blame it on the genes; if someone's brain doesn't work properly, we blame the school. It's actually more humane to think of the condition as genetic. For instance, you don't want to say that someone is born unpleasant, but sometimes that might be true.
