Asymmetrical pollen grains are preferred by nature - life short science news

Plants favor the production of uneven, asymmetrical patterns on the surface of pollen grains over more symmetrical patterns, a new study shows.

It seems that pollen evolve into asymmetrical pattern because of kinetic arrest of pattern evolution, which would lead to symmetrical forms when pattern evolution is completed.

This interpretation was made possible with a biophysical model that researchers hope to refine to shed more light on pollen evolution and to explore the possibility of designing artificial pollen.
