Detailed explanation-1: -All organisms have a common ancestor as indicated by the third postulate of the cell theory stated by Rudolf Virchow. He states that all cells arise from pre existing cells. This means that there must be one single ancestor cell which is divided to form new cells.
Detailed explanation-2: -The Cell Theory Is a Unifying Principle of Biology The cell theory states that all biological organisms are composed of cells; cells are the unit of life and all life come from preexisting life. The cell theory is so established today that it forms one of the unifying principles of biology.
Detailed explanation-3: -Big Ideas: All living things have certain traits in common: Cellular organization, the ability to reproduce, growth & development, energy use, homeostasis, response to their environment, and the ability to adapt. Living things will exhibit all of these traits.
Detailed explanation-4: -DNA. All cellular life has a double stranded DNA genome organized into one or more chromosomes-the DNA carrying the required information of life. This DNA carries information used to direct reproduction, intake of food, response to stimuli in its environment and any other typical functions.
Detailed explanation-5: -Rudolf Virchow famously stated “Omnis cellula e cellula”… “All cells only arise from pre-existing cells.
