What evidence indicates that the mosses evolved from the green algae? |
| Answer» Algae\xa0do not keep the embryo inside of themselves but release it into water. This was the first feature to\xa0evolve\xa0that separated\xa0plants\xa0from green\xa0algae. This is also the only adaptation shared by all\xa0plants. Over time,\xa0plants\xa0had to\xa0evolve\xa0from living in water to living on land.\xa0The\xa0evidence suggests\xa0that land\xa0plants evolved\xa0from a line of filamentous\xa0green algae\xa0that invaded land about 410 million years ago during the Silurian period of the Paleozoic era.\xa0All\xa0green algae\xa0(Chlorophyta) and\xa0plants\xa0share a common evolutionary ancestor. They both contain the photosynthetic\xa0pigments\xa0chlorophyll a and chlorophyll b. The two lineages diverged between 630 million and 510 million years ago. | |
