Dolphins recorded having a conversation 'just like two people' for first time

Two dolphins have been recorded having a conversation for the first time after scientists developed an underwater microphone which could distinguish the animals' different "voices".

Researchers have known for decades that the mammals had an advanced form of communication, using distinctive clicks and whistles to show they are excited, happy, stressed or separated  from the group.

But scientists have now shown that dolphins alter the volume and frequency of pulsed clicks to form individual "words" which they string together into sentences in much the same way that humans speak.

Researchers at the Karadag Nature Reserve, in Feodosia, Ukraine, recorded two Black Sea bottlenose dolphins, called Yasha and Yana, talking to each other in a pool. They found that each dolphin would listen to a sentence of pulses without interruption, before replying.

Motherless babies possible as scientists create live offspring without need for female egg

The technique raises the possibility that gay men, for instance, could have a child whose DNA was half of each of the couple, although a woman would still need to act as a surrogate to carry the baby.

It also raises the possibility that a man could even fertilise his own cells to produce offspring containing a mixture of genes inherited from him and his parents.

More realistically, the technique could allow women whose fertility has been wiped out by cancer drugs or radiotherapy to have their own children.
