An ancestral gene coding for the synthesis of enzymes called kinases played a vital role in the evolution of all complex life forms.
If you’re reading this, you’re probably a eukaryote. This is the name given to complex life forms with cells that contain nuclei and other specialized organelles. However, while most of us take these characteristics for granted, scientists have spent several decades trying to identify the particular genetic event that enabled such wonderfully intricate beings to evolve from basic bacterial sludge – and they may have finally cracked it.
