Prof Conway Morris believes that extraterrestrial life is most likely to occur on a planet similar to our own, with organisms made from the same biochemicals. The process of evolution will even shape alien life in a similar way, he added.Note that "Darwinian" here seems to mean "destined to produce symmetrical bipeds with heads."
“It is difficult to imagine evolution in alien planets operating in any manner other than Darwinian," he said.
"In the end the number of options is remarkably restrictive. I don't think an alien will be a blob. If aliens are out there they should have evolved just like us. They should have eyes and be walking on two legs.
"In short if there is any life out there then it is likely to be very similar to us."
