Recent research indicates that the origins of complex cells, known as eukaryotes, are more intricate than previously thought. Traditionally, it was believed that eukaryotes emerged from a fusion of archaeal cells and bacteria, with bacteria evolving into mitochondria. However, a new study suggests that multiple waves of gene transfers from bacteria contributed to the eukaryotic genome, indicating that gene transfers among species were common during the evolution of complex cells.

Study Reveals Complex Origins of Eukaryotic Cells
A new study has found that the origins of eukaryotic cells are more complex than the previously accepted model of a simple fusion between archaeal cells and bacteria. The research highlights multiple instances of gene transfer from bacteria to eukaryotes, suggesting a more dynamic evolutionary process.
