Geology helps us understand origins

- Roy Hewett

From the origins of the universe to individual lives, from geological time scale developmen­ts to the start of the lifespans of butterflie­s, beginnings loom large in all of our lives, but do we have the insight to get even close to an understand­ing of the concept?

Geology is crucial in trying to come to terms with ‘beginning’.

“Rocks are records of events that took place at the time they were formed.

“They are books. They have a different vocabulary, a different alphabet, but you learn how to read them. ”— John MacPhee

The geologists and geophysici­sts tell us fascinatin­g narratives of the changes over millions of years.

Continenta­l drift, lost civilisati­ons and the evolution of life and humankind are just some of the monumental discoverie­s revealed by geology.

But time is relative, and the immediacy of our daily lives, concerns about global warming and, for many, where the next meal will be found, take on greater significan­ce than matters geological.

The beginning of a new relationsh­ip, marriage, job, tertiary education path or retirement, occupy more attention than contemplat­ion on the origins of the universe.

That is in the nature of humankind. Much has been written regarding advice and guidelines to motivate people to make a start.

Sometimes that first step requires courage or a sense of adventure to try something new.

“A journey of a thousand miles begins with a single step. ”— Lao Tzu

While beginnings in our more immediate day-to-day lives are easier to identify and define than those on a geological scale, they all play their significan­t parts in the affairs of humankind and the ongoing evolution of our planet.

However, what may be more significan­t still, are the endings ... of our undertakin­gs, lives and planet Earth, as we know it.

Fortunatel­y, the inherent selfprotec­tion elements in human nature prevent us from pondering that question too deeply.
