Testing the two hypotheses (1 of 4)
Comparing the evidence for two opposing hypotheses.

Testing the two hypotheses (2 of 4)
Examining the evidence for two hypotheses: the endosymbiotic or step-by-step origins of mitochondria, plastids, and tubule organelles.

Testing the two hypotheses (4 of 4)
A group of scientists showed that if you remove tubule organelles from a eukaryotic cell, they can grow back. This discovery argued against the idea that these organelles evolved via endosymbiosis.
