Lewis Wolpert, the Emer­i­tus Pro­fes­sor in Cell and Devel­op­men­tal Biol­ogy at UCL who gave the Is Sci­ence Dan­ger­ous? lec­ture (pdf) at the 120th Nobel Sym­po­sium, recently wrote the book Six Impos­si­ble Things Before Break­fast.

In this book Wolpert explores the evo­lu­tion­ary ori­gins of belief, and ABC News dis­cusses this opin­ion in Why Do We Believe Impos­si­ble Things?

[O]ur wide range of beliefs, some of which are clearly false, grew out of a uniquely human trait. Alone in the ani­mal world, humans under­stand cause and effect, and that, he says, led ulti­mately to the inven­tion of tools, the rapid rise of sophis­ti­cated tech­nol­ogy, and of course, beliefs. Even the ear­li­est humans under­stood that many events that shaped their lives resulted from spe­cific causes. There­fore, there must be a cause behind every event.

Search­ing for that cause, Wolpert says, led to the rise of reli­gion because surely there must be some pur­pose behind all this, some ulti­mate cause at work in the universe.
