The process of evolution has produced a world of great beauty, diversity and complexity. Ants form structured societies, trees reach for the skies, and whole ecosystems thrive in inhospitable-sounding places like underwater caves, deserts or deep-sea trenches. Where the air is clean, rocks and anything else that doesn’t move is covered with a crust of lichen – a partnership between fungus and algae (or bacteria) that survives even the harshest of weather.

Denis Alexander spoke on this subject at the Faith and Thought conference in October last year. I was fascinated to hear about the changes in ideology among scientists over time, and I wonder how their views will develop in future years? Continue reading
