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.
Because lots of evidence supports scientific theories, they are usually accepted as true by a majority of scientists. Hereâs a brief summary of the evidence that supports the theory of evolution by natural selection: Biochemistry is the study of the basic chemistry and processes that occur in cells. The biochemistry of all living things on Earth is incredibly similar, showing that all of Earthâs organisms share a common ancestry.
