Pieces of DNA that predict lifespan are shorter in birds that are inbred, according to new research from the University of East Anglia (UEA).
The findings mean that inbreeding could be linked to a shorter lifespan.
The team also found effects that spanned generations -- with the young of inbred mothers also being negatively affected.
The DNA pieces in question, known as telomeres, are found in almost all animals -- including humans.
They act as protective caps at each end of a chromosome -- providing protection from damaging substances.
