Carboxysomes: Tiny Machines in Cyanobacteria Defy Darwin, Inspire Product Development

Evolutionists would agree that cyanobacteria are one of the oldest organisms alive today. These tiny bacteria have hardly changed in “3 billion years” or so.

A news item published by the University of Liverpool, UK. states:

Cyanobacteria are a phylum of bacteria that produce oxygen and energy during photosynthesis, similar to green plants. They are among the most abundant organisms in oceans and fresh water. Unique internal ‘machines’ in cyanobacteria, called carboxysomes, allow the organisms to convert carbon dioxide to sugar and provide impacts on global biomass production and our environment.”

They are anything but simple.

Carboxysomes are so elegant and efficient that researchers would like to draw inspiration from how they work:

The self-assembly and modularity features of carboxysomes make them interesting systems for nanoscientists, synthetic biologists and bioengineers, who hope to find ways to design new nanomaterials and nano-bioreactors.”

Darwinian mechanisms cannot produce tiny machines that are far more effective than anything human researchers have come up with.
