From the Ted Talk by Jonathan Drori: Every pollen grain has a story

Unscramble the Blue Letters


Pollen is tiny. It gets on to things, and it stciks to them. So, not only does each type of pollen look different, but each habitat has a different combination of plants. A different pollen sirtnugae, if you like, or a different pollen fninigperrt. By looking at the proportions and combinations of different kinds of pollen in a sample, you can tell very precisely where it came from. This is some pollen emedbded in a cotton shirt, sialmir to the one that I'm wearing now. Now, much of the pollen will still be there after repeated washings. Where has it been? Four very different habitats might look similar, but they've got very different pollen signatures. Actually this one is particularly easy, these pictures were all taken in different countries.

Original Text


Pollen is tiny. It gets on to things, and it sticks to them. So, not only does each type of pollen look different, but each habitat has a different combination of plants. A different pollen signature, if you like, or a different pollen fingerprint. By looking at the proportions and combinations of different kinds of pollen in a sample, you can tell very precisely where it came from. This is some pollen embedded in a cotton shirt, similar to the one that I'm wearing now. Now, much of the pollen will still be there after repeated washings. Where has it been? Four very different habitats might look similar, but they've got very different pollen signatures. Actually this one is particularly easy, these pictures were all taken in different countries.
