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 (3 of 4)
New sequencing technologies leads to the evidence that both mitochondrial and plastid DNA are more similar to bacterial DNA.

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.
