So whatís the most successful plant on the planet? Which species has the greatest biomass?
Trick question. The answer is a few types of sea-growing algae.
Okay, so whatís the most successful land-based plant on Earth? The answer is rice. Itís not only the single species with the greatest biomass, but it also has the greatest growing range. With the rather notable exception of Antarctica, itís being cultivated right this minute on every continent.
Itís no accident that the favorite food of the most successful non-insect life form on the planet is also very successful. We make sure that this is so. We have to. If we didnít aggressively cultivate food crops then there wouldnít be enough for about 90% of the people alive today.
But we do more than protect and extend our food supply. We also shape it through the centuries. Ancient man cultivated seeds from the plants that produced the highest yields in an attempt to get more bounty from less work. The most striking example of this can be found by comparing the size of corn ears (aka maize) from ancient times to today. The evolutionary pressure that caused such a massive change in so short a time was entirely due to humans.
The reason why Iím boring all of you to tears with this opening lecture from Archeology 101 is due to this news article, which states that the main reason why flowers are so varied and successful is due to the emotional reaction that most people have for them.
Well, DUH! Every culture that has developed agriculture and lives above a subsistence level cultivates flowers. There has to be a reason why, and getting your favorite girl to crack a smile is one of the best there is.
If anyone is interested in this subject, I suggest that they read The Tulip: The Story of a Flower That Has Made Men Mad. Pretty good stuff.
