INSIGHT

Life's Biochemical Limitation

Life's biochemical diversity is limited, using only 22 amino acids and 5 nucleobases despite countless possibilities.
Synthetic biology seeks to expand this chemical repertoire to explore new biological functionalities and understand life better.

INSIGHT

Multiple Origins but Single Survival

Life likely originated multiple times on Earth but only one lineage survived and dominated.
Once life dominates, new origins struggle due to competition and predation by established life.

INSIGHT

Ribosome's Primitive Mechanism

Ribosomes are primitive molecular machines that assemble proteins indiscriminately, enabling translation of many amino acids.
Their simplicity reflects evolutionary 'frozen accident' and limits how much they've evolved.
