Summary Of Life Begins: Crash Course Big History
In John/Hank Green’s video, “Life Begins: Crash Course Big History #4,” he discusses many different concepts encompassing the beginning of life on Earth.

Science claims that cells are the smallest units of living organisms. When the two units become joined together, a new cell, a living organism, forms. This contradicts the statement that life happens for the baby after the woman conceives.…

    Lamarck's Theory

    Before Lamarck, not even scientists and scholars have the idea of finding the genesis of life on earth. What was widely accepted at that time was that the world was created by God. Creatures acted in certain patterns as they were made to be. Also organisms were not considered to be changeable over time. Two hundred years ago, however, Jean-Baptiste Lamarck (hereinafter referred to as Lamarck), raised the first theory of evolution which totally disputed this former cognition.…

    is there life on other planet

    Evolutionists have different view about the origin and evolution of life (steady development of the diversity of living things from a common ancestor). Evolutionists say that living and non-living things arose from natural procedure, and they believe that life can exist on any place on the universe. “If life did arise on earth by itself, it would be inconceivable that this is the only planet upon which there is life” (Danny Faulkner). In recent years many scientists searched for extraterrestrial life in outer space, but there was no strong evidence for life in outer space. Yet, they believe, if life has existed from past in the Earth sustaining the climatic change of the Earth, there can be some evolution of life regarding to the climatic condition of other planets. Similarly, Darwin theory of evolution suggests “where life can take hold, it will”, so, one day we might see life on other planet adapting the environment.…
