If you’re sneezing this spring, you aren’t on my own. Once a year, vegetation liberate billions of pollen grains into the air, specks of male reproductive subject matter that many people realize most effective after we get watery eyes and runny noses.
Then again, pollen grains are excess of allergens – they’re nature’s time tablets, conserving clues about Earth’s previous environments for hundreds of thousands of years.

The varieties of pollen and the amounts of pollen grains discovered at a website lend a hand researchers reconstruct historic forests, observe sea-level adjustments and determine the fingerprints of important occasions, corresponding to asteroid affects or civilizations collapsing.
As palynologists, we find out about those historic pollen fossils around the globe. Listed here are a couple…
