structures evolved as plants colonized the land‚ and in some lineages they became systems of roots. Most roots had a large surface area that helped plants absorb more water and dissolved mineral ions. As they do today‚ young roots probably associated with fungal mycorrhizal symbionts‚ which help plants obtain water and dissolve nutrients. In many lineages‚ older roots started anchoring the plant. Above ground‚ shoot systems evolved. Their stems and leaves captured energy form the sun and carbon dioxide

one species exists today—Homo sapiens‚ or human beings. Dr. Alistair Evans and his colleagues based their study off of hominin tooth sizes while trying to figure out what rule governed the evolution and development of teeth in hominins. This study provides a development-based expectation to examine the evolution of the unique proportions of human teeth. While on their journey‚ Dr. Evans and his crew found two types of hominins: the species that we classify as Homo and australopiths. These scientists
