This is 'convergent evolution' at work.
may have just discovered the reason for the remarkable intelligence in octopuses and active jumping genes. Interestingly, the jumping genes found active in octopuses are also active in the human brain,The octopus is a unique animal.
Previous sequencing studies have shown that transposons occupy as many as 45 percent of the human genome, providing it the potential to be duplicated or shuffled. Such duplications or shufflings do not usually create visible effects on the organism and are called silent transposons. Over the years, some transposons have become inactive, as they have accumulated mutations that prevent them from jumping around while retaining the capacity to jump but are blocked by the cell's defense systems.
