As humans embrace technological advances and gradually become androids, we could gradually see Homo sapiens being replaced by Homo optimus. This conceptual image shows four stages of human evolution (left to right) showing Australopithecus, Homo habilis, Homo erectus and Homo sapiens

'This could give rise to some weird and wonderful future forms and creations – from changing video displays on our faces to controlling our own dreams - our (evolving) imaginations are the only limit.'

Dr Pearson believes that with a full link between the human brain and a computer, people could move their mind into an improved android body.

'This would allow people to have multiple expistences and identities, or to carry on living long after their biological death,' he wrote in the 'Future Human Report.'

While this technology could be available as soon as in 2050, it may become cheap enough to be widespread by 2070.

Plus, by the end of the century, there will likely be several types of humans, including human-machine hybrids, and people living in android bodies, as well as 'smart creatures'.

Dr Pearson continued that anyone under the age of 40 today will have a good chance of electronic immortality, meaning they could essentially 'upload' their personality so it can continue posting after their death.
