The Book of Seeds

We’re excited that you’ve joined the conversation! At HMU, we want to continue the great authors’ conversations in a contemporary context, and this blog will help us do that. We look back to Aristotle and the early philosophers who used reason and discourse to gain wisdom and now we endeavor to do the same every day.

Spring is upon us. Just as blossoms begin to show their strength, color, and vibrancy, so too the weather changes and begins to warm. All of the seasonal changes often add up to a change in attitude as well. Flowers, I believe, bring out the best of human nature, fostering images of beauty, strength, love, hope, and imagination. But where does the beauty begin? How does the flower take root and gain enough energy to grow their blooms?

Paul Smith begins his recent book The Book of Seeds; A Life-size Guide to Six Hundred Species from Around the World (2018) with the following lines:

“Seeds are amazing. They can travel thousands of miles across oceans and continents, and can live for hundreds of years. A seed no bigger than a pinhead can grow into the tallest living organism on the planet. The smallest seed can barely be seen with the naked eye; the largest is the size of a human head. Over a period of more than 300 million years, seeds have evolved into every size, shape, and color imaginable” (6).

All of that seems amazing when one considers how little we discuss seeds in comparison to how much time is spent on animals, even extinct animals such as dinosaurs. Often we fail to notice the same awe-inspiring capabilities from plants of the same time period – ones to which we still have access! Paul Smith continues:

“Plant life on land evolved a staggering 600 million years ago, with the ancestors of many of these early plants still extant today: the mosses, clubmosses, horsetails, and ferns. These species don’t produce flowers or seeds; instead, they reproduce through spores. It was not until approximately 240 million years later that the first primitive seed-bearing plants appeared, an adaptation that conferred numerous advantages for survival, including the capacity for sexual reproduction in the absence of water, the ability to disperse over long distances, and the adaptability to survive in a dormant state for long periods of time until the right conditions arose. Today, the vast majority of plant species (more than 80 percent) are found in the tropics, but even places as inhospitable as Antarctica and the Sahara Desert support seed-bearing plant species” (7).

Seeds have adapted many tricks to optimize their environments. For example, some seeds remain dormant for long periods of time waiting until the conditions are ripe for life. Smith explains that some seeds, particularly those in warm, wet environments, do not remain dormant. Instead of storing energy, they choose to sprout quickly and gain access to the immediate environmental benefits. Other seeds, like the coconut, float which enables them to travel greater distances to access better growing conditions. Many seeds may remain dormant for years. One of the greatest examples of this was found in the 1960s during an excavation at King Herod’s palace in Israel. A 2,000 year old date palm seed was found among the ruins and when planted, it grew normally.

More impressive than their amazing adaptations, however, is the important part that seeds play in determining human existence. Without plants that can be planted and cultivated as a food source, humans would have to remain hunter gatherers. Seeds, especially the ones that can be saved and transported, allow humans to move to a new place, or stay in one place. The ability to grow foods impacts social connectivity and health. Smith writes, “The adaptive leap that humans made from collecting grains and seeds to planting and harvesting them seems to have occurred in parallel in several different places” (18). This astounding idea – that multiple communities who did not know of each others’ existence arrived at cultivation simultaneously indicates something important about the nature of humans and of our interaction with the planet. Smith notes that around 9500 BCE Wheat, Barley, Pea, and Lentil “were domesticated in the Fertile Crescent – what is now Iran and Iraq” (18). From there, he continues:

“At around the same time, Rice was first cultivated in China, followed by Soybean. In the Andes, the Potato was domesticated around 8000 BCE, together with beans. In New Guinea, Sugarcane and the Yam appear in the archeological record about 7000 BCE. In Africa, Sorghum was domesticated in about 5000 BCE, and in Central America, Maize was first cultivated around 4000 BCE. Domestication of livestock occurred over a similar period of time. The transformation of wild plants into crops through artificial selection and breeding enabled human communities to establish themselves in villages, towns, and cities, and to flourish” (19).

While the history of seeds is astoundingly impressive (and seeds themselves are as diverse as imaginable), more importantly, however, may be the future of plants. Smith claims that plant diversity is of utmost importance since the majority of life on earth depends upon plants. He notes that we have studied relatively few, however. He claims that plants seem nondescript, but they have important roles in our daily lives. Smith ends his introduction with a quote by Aldo Leopold which underscores the point that humans would better serve themselves and the earth by adding a curious intelligence into their dealings with plants. He quotes, “If the biota, in the course of aeons, has built something we like but do not understand, then who but a fool would discard seemingly useless parts? To keep every cog and wheel is the first precaution of intelligent tinkering” (27).

I highly suggest thumbing through this massive collection of seeds. The diversity and colorful arrays are astounding. It will leave you with yet another reminder of the world’s vast richness.
