I am pleased to be part of Jacqui Murray’s Book Blast for her third and final book in the Dawn of Humanity series, Natural Selection. Once again Jacqui has penned an exciting story about our prehistoric ancestors. She will also share with us how early humans told time. The research Jacqui does for these books is phenomenal.

Summary
In this conclusion to Lucy’s journey, she and her tribe leave their good home to rescue former-tribe members captured by the enemy. Lucy’s tribe includes a mix of species–a Canis, a Homotherium, and different iterations of early man. In this book, more join and some die, but that is the nature of prehistoric life, where survival depends on a combination of our developing intellect and our inexhaustible will to live. Each species brings unique skills to this task. Based on true events. Set 1.8 million years ago in Africa, Lucy and her tribe struggle against the harsh reality of a world ruled by nature, where predators stalk them and a violent new species of man threatens to destroy their world. Only by changing can they prevail. If you ever wondered how earliest man survived but couldn’t get through the academic discussions, this book is for you. Prepare to see this violent and beautiful world in a way you never imagined.

A perfect book for fans of Jean Auel and the Gears!

How Did Early Man Tell Time?

Like today’s most primitive communities and survivalists, both living without the technology that ticked off hours and minutes, earliest man had no concept of quantifiable time. He didn’t need it when the most important metric was how much daylight remained to finish hunting and gathering and find a safe place to sleep. He told tribe members when he would return–or they
should–well, I’ll tell you how that happened later in this article. When the sun slept, our primeval ancestors slept, leaving whatever chores remained for the next day and the sun’s return.

In Natural Selection, that usually sufficed, but if a character needed more than that, say to indicate more definitively when s/he would return:

– s/he could point to a place in the sky along the sun’s forward path, the inference being when sun reached that position, s/he would be back.
– s/he could place a finger–or a hand–overhead, next to the sun, inferring that when the sun moved the width of a finger or a hand, s/he would return.
– at night, the Moon’s progression across the night sky could be used to indicate how long before the sun reappeared.

For longer periods of time, beyond a stretch of daylight, early man used the Moon’s face. It changed nightly and with regularity. The disappearance and reappearance of the Moon, the size of the orb, made it a reliable marker of how long something took or the period before something happened, like herds returning or hunters arriving from a long trip.

How long is a hand or finger? So how much time is inferred by a finger or a hand placed next to the sun? A finger is roughly
fifteen minutes and four fingers—a hand—an hour. Test it yourself. Place a finger next to the sun. The sun will take approximately fifteen minutes to reach the far side of your finger. If there is one hand between the sun and the earth, it means there is one hour until the sun sinks below the horizon. 

Early man knew that the sun moved at the same speed across the sky which meant a hand or both hands always meant the passage of the same amount of time. What he didn’t know was why. Here’s the reasoning he wouldn’t learn for thousands of years, but will be clear to you:
Take your height, for early man about 5 feet.
Multiply it by 1.5 = 7.5
Find the square root = 2.7
That means 2.7 miles to the horizon, or about two hours of walking on their bandy legs.

Do you have any tips for telling time without a watch or phone?

What readers are saying about Natural Selection

“In the third book of the series, Lucy is again beset with challenges.
Besides Lucy struggling to keep her tribe safe, and free the tribe members that were stolen by an enemy tribe—plenty to grab and hold a reader’s attention—there were substories hurtling through the book with characters I grew to care about. A Canis tracking another Canis to be her mate. A Homotherium kit looking for a pack. And Lucy’s former pack members that have been enslaved and are looking for a way to survive and escape their bonds.

Once again, Ms. Murray has woven prehistory into a lovely, understandable story. One of her signature themes is the blending of different cultures into one tribe. Proving that in spite of our differences we can get along.
On a personal note, I loved that Boah said goodbye. (You’ll know what I’m referring to when you read it.) And last but not least my favorite quote: “If Night Sun knew, it wasn’t telling.”

NATURAL SELECTION is a must-read for all Murray fans, of which I am one, prehistory buffs AND for folks that just like a well-told tale.” Sandra Cox

“The final book of the Dawn of Humanity series ends on a positive note though I suspect that Lucy’s story of survival in the prehistoric world will continue to be riddled with danger and challenges. As the title suggests, not all the branches of primitive mankind will survive and those who do will depend on their ability to develop new skills and think strategically.

The plot is straightforward with two main threads. The first is Lucy and her group’s continuing search for a sustainable home base. The second is their plan to rescue past members of her tribe from Man-who-preys before they become so weak from hunger that they’re killed. Lucy is the main character, but not the only point of view, and other characters are frequently brought to the forefront. These include her two-legged group members as well as those with four.

Murray’s research continues to add depth and realism to the read, and I found it as fascinating as I did in the first book. Our ancestors had it tough, and their lives were intricately entwined with the world around them. I appreciated that Murray didn’t spare our modern sensibilities. Grooming bugs from each other’s skin, eating rotten meat, and “fear poop” aren’t very glamorous, but they added to the authenticity of the story. Her word choices—to describe the harsh environment, its rhythms and wild creatures, and the nature and skill of each member of her diverse group—bring life on Earth 1.8 million years ago into vivid relief.

For readers who enjoy a meticulously researched primitive world and the remarkable challenges faced by our evolutionary ancestors, I highly recommend this series. It’s fascinating.”
