\u00a0<\/span><\/p>\nAs evolution searches over possible genomes, simple algorithms are more likely to be discovered \u2013 as are, in turn, the more symmetric structures that they produce. The scientists then connected this evolutionary picture to a deep result from the theoretical discipline of algorithmic information theory.<\/p>\n
“These intuitions can be formalised in the field of algorithmic information theory, which provides quantitative predictions for the bias towards descriptive simplicity,” added Ard Louis, professor at the University of Oxford and corresponding author on the study.<\/p>\n
How can scientists demonstrate this theoretical idea?<\/h3>\n The study\u2019s key theoretical idea regarding symmetry in evolution can be illustrated by a twist on a famous thought experiment in evolutionary biology, which pictures a room full of monkeys trying to write a book by typing erratically on a keyboard. Imagine the monkeys are instead trying to write a recipe. Each is far more likely to randomly hit the letters required to spell out a short, simple recipe than a long, complicated one.<\/p>\n
If we then follow any recipes the monkeys have produced \u2013 our metaphor for producing biological structures from genetic information \u2013 we will produce simple outcomes much more often than complicated ones.<\/p>\n
The scientists intend to reveal that a wide range of biological structures and systems, from proteins to RNA and signalling networks, adopt algorithmically simple structures with probabilities as predicted by this theory. Going forward, they plan to investigate the predictions that their theory makes for biases in larger-scale developmental processes.<\/p>\n
