Earth Science: Evolution – Evolutionary Factors Following the synthetic theory of evolution, the development of life proceeds nondirectionally through the random effect of evolutionary factors. Selection and genetic drift are the most important evolutionary factors. Earth Science: Biology – Evolution – Selection Organisms that are particularly well adapted to their environment generally have better chances … Read more
Discovery Science: Earth – Biology – Evolution About 3.5 billion years ago, the first signs of life on Earth were single-celled bacterial organisms that lived in the primeval oceans. Single-celled animals and algae, as well as all multicellular organisms, evolved from these bacteria. This evolutionary process was limited to the oceans for many millions of … Read more
