They can affect the DNA of living things over time.

They occur in thousands of years or within billions of years.

They affect the populations and species more slowly then short term changes .

Explanation:

The long-term environmental changes are slow and gradual changes in the environment. This gives the population of the species the opportunity to adapt. These occur on Earth over thousands of years.  The gradual changes affect the body form and function of living beings. The gradual changes can affect the instructional machinery like DNA synthesis and its function.  Such changes develop unnoticeable and undetected symptoms in species. The fluctuation of climate in a region over thousand years can bring a catastrophic hazard like cyclone.

They can affect the DNA of living things over time.

They occur in thousands of years or within billions of years.

Explanation:

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.

just don't strip down in public lol
