Detailed explanation-1: -1) DNA sequencing is the best method to determine that whether to transmission share recent common ancestor…
Detailed explanation-2: -If two or more species share a unique physical feature, such as a complex bone structure or a body plan, they may all have inherited this feature from a common ancestor. Physical features shared due to evolutionary history (a common ancestor) are said to be homologous.
Detailed explanation-3: -DNA evidence for evolution Biologists often compare the sequences of related (or homologous) genes. If two species have the “same” gene, it is because they inherited it from a common ancestor. In general, the more DNA differences in homologous genes between two species, the more distantly the species are related.
Detailed explanation-4: -In contrast, shared metabolism, DNA sequences, and genetic code are all indicators that two species (or all species, in the case of the genetic code) share an evolutionary common ancestor.
Detailed explanation-5: -Plants, animals and bacteria share a common ancestor, known as LUCA (the Last Universal Common Ancestor). A later common ancestor, LECA, is shared by all eukaryotes (Last Eukaryotic Common Ancestor). LUCA and LECA were sophisticated cells.
