Evolution over the millennia has resulted in the great variety of life on Earth. Yet scientists hypothesize all life has descended from an ancestral one-celled organism. What provides the most compelling evidence from this statement?

Respuesta :

Answer:

Through numerous experiments scientists have find that Archaebacteria can withstand extreme climatic conditions that have been occurred in the past like Ice Age.

Explanation:

Last Universal Common Ancestor (LUCA) is the single common ancestor of all extant creatures. Archaebacteria are single celled organism that are able to survive extreme weather conditions like hot thermal vent, oxygen-free wetland, etc. William Martin, a biologist tried to track down LUCA in bacteria and archaea. After analyzing the genes, researchers found nearly 350 gene family quite similar to those of archaebacteria. So, it was concluded that LUCA was a single-celled organism that lived in hydro-thermal vents where seawater and magma meet at ocean floor.

Without mincing words, it is expedient to note that life starts from a unicellular organism which is the basis of the scientific studies over the years. As the cell divides we later have multicellular organisms and life continues.
