Please Explain Why Most Scientists Now Accept the Idea That

Question

Examlex · Accepted Answer

The Answer is Most scientists now accept the idea that the most recent common ancestor of eukaryotes likely possessed mitochondria because of a combination of genetic, biochemical, and evolutionary evidence.

Genetic studies have shown that the DNA of mitochondria is more closely related to the DNA of certain bacteria than it is to the DNA of the eukaryotic cell in which it resides. This suggests that mitochondria were once free-living bacteria that were engulfed by a primitive eukaryotic cell and eventually formed a symbiotic relationship with it.

Biochemical studies have also revealed that mitochondria have their own unique DNA, ribosomes, and protein synthesis machinery, which are similar to those found in bacteria. This further supports the idea that mitochondria were once independent organisms.

Additionally, the endosymbiotic theory, which proposes that mitochondria and chloroplasts were once free-living bacteria that were engulfed by primitive eukaryotic cells, has gained widespread acceptance among scientists. This theory provides a plausible explanation for the origin of mitochondria and is supported by a wealth of evidence from various fields of study.

Overall, the combination of genetic, biochemical, and evolutionary evidence has led most scientists to accept the idea that the most recent common ancestor of eukaryotes likely possessed mitochondria.
