<ul>
<li><span>Evolution refers to the gradual change of species.</span></li>
<li>Fossils are remnants of organisms.</li>
<li>By comparing the structure of organisms and the stages of individual development, the development and relatedness of species are determined.</li>
<li>New species develop over long periods of time, e.g. with population isolation and mutations.</li>
<li>Life was formed in the ocean.</li>
<li>Life gradually moved to land during the Paleozoic era. The presence of ozone layer (which was created as a result of photosynthesis) enabled organisms to develop and live on <strong>land</strong>.</li>
<li>Dinosaurs were the dominant animals of the Mesozoic era.</li>
<li>Birds and mammals have spread to different ecosystems in the Cenozoic era.</li>
<li>Keywords: fossil, vestige, selective breeding, genetic similarity, natural selection, species, biological evolution, cultural evolution, geological eras of life; Precambrian era, Paleozoic era, Mesozoic era, Cenozoic era</li>
