Based on decades of accumulated evidence, the scientific community supports Margulis's ideas: endosymbiosis is the best explanation for the evolution of the eukaryotic cell. What's more, the evidence for endosymbiosis applies not only to mitochondria, but to other cellular organelles as well. Chloroplasts are like tiny green factories within plant cells that help convert energy from sunlight into sugars, and they have many similarities to mitochondria.
Creationists commonly advance the tautology argument somewhat as follows: The theory of evolution is built around the phrase Survival of the Fittest (SoF), but since the only measure of fitness is the survival rate, this phrase actually reduces to Survival of the survivors which is circular and thus an empty tautology.
