Phobias may be memories passed down in genes from ancestors
Memories may be passed down through generations in DNA in a process that may be the underlying cause of phobias
Memories can be passed down to later generations through genetic switches that allow offspring to inherit the experience of their ancestors, according to new research that may explain how phobias can develop. Scientists have long assumed that memories and learned experiences built up during a lifetime must be passed on by teaching later generations or through personal experience. However, new research has shown that it is possible for some information to be inherited biologically through chemical changes that occur in DNA. Researchers at the Emory University School of Medicine, in Atlanta, found that mice can pass on learned information about traumatic or stressful experiences – in this case a fear of the smell of cherry blossom – to subsequent generations. The results may help to explain why people suffer from seemingly irrational phobias – it may be based on the inherited experiences of their ancestors.

That’s pretty amazing.
This has some very disturbing implications.
It would only apply to things that happened to our ancestors before they reproduced, too. So we’d never learn to be afraid (through this mechanism) of whatever actually killed our predecessors…
How have I never been to a sixpack swap party before?

· 72 percent of respondents had experienced intimate partner violence, compared to a quarter of all U.S. women.
· Fewer than half of respondents said that a healthcare provider had told them that the chance for transmitting the virus is very low when the amount of HIV in the bloodstream is low, a core tenet of the treatment as prevention approach to encouraging people living with HIV to adhere to their medications.
· 39 percent reported wanting children in the future, but the women themselves — not their healthcare providers — are more likely to initiate conversations about fertility and reproductive options.
· Nearly two-thirds of respondents said they had a poor perception of their bodies after receiving their diagnosis. In written responses, they frequently described themselves as “dirty,” “diseased,” “ugly” and “unwanted.”
