A scientist discovered a new group of unicellular organisms that lack mitochondria but possess an organelle related to the endoplasmic reticulum and is involved in energy production. The scientist hypothesizes that this organelle might be a missing link in the evolution of mitochondria. A) Do you agree with this hypothesis? Explain. B) Based on the available evidence, what is the most likely hypothesis for the origin of mitochondria? Provide four pieces of evidence to support this theory and justify why they are valid.

Prokaryotic evolution

The term evolution means the gradual change or a transformation from a simple or primitive state to a complex or advanced state. Prokaryotic evolution is a concept that involves the evolution of the form and function of most primitive organisms (prokaryotes) through several stages and changes to form diverse life as a part of organic evolution.
