Common descent is a concept in evolutionary biology applicable when one species is the ancestor of two or more species later in time. According to modern evolutionary biology, all living beings could be descendants of a unique ancestor commonly referred to as the last universal common ancestor (LUCA) of all life on Earth.
Christopher Columbus [b] (/ k ə ˈ l ʌ m b ə s /; [2] between 25 August and 31 October 1451 – 20 May 1506) was an Italian [3] [c] explorer and navigator from the Republic of Genoa [3] [4] who completed four Spanish-based voyages across the Atlantic Ocean sponsored by the Catholic Monarchs, opening the way for the widespread European exploration and colonization of the Americas.
The 15th-century explorer Christopher Columbus was a Sephardic Jew from Western Europe, Spanish scientists said on Saturday, after using DNA analysis to tackle a centuries-old mystery. Many ...
Human DNA recovered from remains found in Europe is revealing our species’ shared history with Neanderthals. The trove is the oldest Homo sapiens DNA ever documented, scientists say.
One of the strongest evidences for common descent comes from gene sequences. Comparative sequence analysis examines the relationship between the DNA sequences of different species, [1] producing several lines of evidence that confirm Darwin's original hypothesis of common descent.

A tree of life, like this one from Charles Darwin's notebooks c. July 1837, implies a single common ancestor at its root (labelled "1"). A phylogenetic tree directly portrays the idea of evolution by descent from a single ancestor. [3] An early tree of life was sketched by Jean-Baptiste Lamarck in his Philosophie zoologique in 1809.
