'Memories' pass between generations
Behaviour can be affected by events in previous generations which have been passed on through a form of genetic memory, animal studies suggest.
Experiments showed that a traumatic event could affect the DNA in sperm and alter the brains and behaviour of subsequent generations.
A Nature Neuroscience study shows mice trained to avoid a smell passed their aversion on to their “grandchildren”.
Experts said the results were important for phobia and anxiety research.
The animals were trained to fear a smell similar to cherry blossom.
The team at the Emory University School of Medicine, in the US, then looked at what was happening inside the sperm.
They showed a section of DNA responsible for sensitivity to the cherry blossom scent was made more active in the mice’s sperm.
Both the mice’s offspring, and their offspring, were “extremely sensitive” to cherry blossom and would avoid the scent, despite never having experiencing it in their lives.
Changes in brain structure were also found.
"The experiences of a parent, even before conceiving, markedly influence both structure and function in the nervous system of subsequent generations," the report concluded.
The Alnwick Poison Garden is pretty much what you’d think it is: a garden full of plants that can kill you (among many other things). Some of the plants are so dangerous that they have to be kept behind bars. [x]

So who was throwing spears before humans? The discovery of 280,000-year-old stone-tipped spear remains in Ethiopia has two possible implications: that our species is much older than previously thought or, more likely, that a predecessor species was making tools long before Homo sapiens.
