Britain is one of the most racially tolerant countries on the planet, a survey claims. The global social attitudes study claims that the most racially intolerant populations are all in the developing world, with Jordan and India in the top five.
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.
The Endosymbiotic Theory is a theory about how mitochondria and chloroplasts formed. The theory suggests that both the mitochondria and chloroplasts were once prokaryotic cell â¦ s that were ingested but not digested by eukaryotic cells.This would explain why both have their own DNA. 10 people found this useful.he strongest piece of evidence for the endosymbiotic theory is the fact that mitochondria and chloroplasts have their own circular DNA, prokaryote fashion, and can still repl â¦ icate, transcribe and translate some proteins. Their ribosomes are also fashioned as a prokaryotes would be.
