Scientists discover we don’t need all of out 20,000 genes to survive

“We have around 24,000 genes that make us uniquely human and, until now, it was thought that if any were missing it could cause serious problems.

But new research has found that around 200 of these genes may in fact be completely redundant, without posing any such risk.

By studying the genomes of 2,500 people, researchers have said they were surprised to see around one per cent of these genes were missing entirely in some participants.

More importantly, these particular people had no significant health defects that would be explained by the missing genes.
