What aspects of your own behavior would you attribute to biology, and what aspects to the environment?

The aspect of behavior to be attributed to biology, are those our "UNCONSCIOUS" behaviors

The aspect of behaviour to be attributed to environment, are those our"CONSCIOUS" behavior.

Explanation: conscious behaviors are those behavior that we are awear of, and had a thought about it, before acting. Like anger, laughter, loving, decision making, and many more. This is a type of behavior that involves ones emotion and thoughts. This is mostly influenced by the environment.

For instance, when someone got sad or happy, it is always a reaction to an action that has acted on the person. When someone wants feels love for a person or thing, it is always reaction to the action the person or thing has showed.

Unconscious behaviour is the tote of behavior that those not involve any thought or emotion, the body just react to it in a particular way, that has been saved in the brain, like walking, sleeping, Reflex actions, and many more. This type of behavior those not need a thought or any emotional attachment to decide how it will be done, and where it will be done.

For instance, when we walk down the staircase, we don't have to think about how to walk or stretch our legs. When we place our hands on a hot iron, we fastly remove our hands without thinking if this will harm us. When we fall asleep, most times we don't even know or consider that we are in a meeting or inside a public bus, because we may have resisted the body it's normal time of sleep and the body needs it then. All this are biological factors that makes one behavior to be that way, because they are not emotionally attached and it doesn't require deep thought before acting.

as university of miami psychologists debra lieberman and adam smith pointed out in a recent article in the journal current directions in psychological science, humans have social and psychological mechanisms to deter incest. with very few exceptions, marriages between brothers and sisters and between parents and their children are verboten in every human culture. the primary psychological anti-incest mechanism is the yuck response. even the idea of sex with their mom or dad, bro or sis is upsetting to most people. the psychologist jonathan haidt has found that nearly everyone is repelled by the prospect of brother-sister sex, even in hypothetical situations in which there is no chance of pregnancy).

the biological cost of incest

this raises an interesting question: just what’s so bad about incest? sure, having sex with your dad or your sister seems gross — but why? some anthropologists have argued that incest taboos are learned social conventions. this explanation, however, doesn’t make sense to me as it does not explain the widespread existence of anti-incest mechanisms in creatures ranging from cockroaches to chimpanzees. second, the incest taboo is about as close to a universal law as human moral rules get.

why should mechanisms to avoid incest be so widespread both in nature and across human societies? the answer is simple. the problem with having sex close with relatives is that there is an astonishingly high chance that your offspring will be born with a serious birth defect.
