Examples of evolves in the following topics:

  • Convergent Evolution

    • Convergent evolution occurs in different species that have evolved similar traits independently of each other.
    • Sometimes, similar phenotypes evolve independently in distantly related species.
    • For example, flight has evolved in both bats and insects, and they both have wings, which are adaptations to flight.
    • However, the wings of bats and insects have evolved from very different original structures.
    • Parallel evolution occurs when two independent but similar species evolve in the same direction and thus independently acquire similar characteristics; for example, gliding frogs have evolved in parallel from multiple types of tree frog.

  • Pre-Cambrian Animal Life

    • Early animal life (Ediacaran biota) evolved from protists during the pre-Cambrian period, which is also known as the Ediacaran period.
    • It is believed that early animal life, termed Ediacaran biota, evolved from protists at this time.
    • Other organisms, such as Cyclomedusa and Dickinsonia, also evolved during the Ediacaran period .
    • Many scientists now believe that animals may, in fact, have evolved during the Cryogenian period.
    • Fossils of (a) Cyclomedusa and (b) Dickinsonia that evolved during the Ediacaran period.

  • Evolution of Amniotes

    • Modern amniotes, which includes mammals, reptiles, and birds, evolved from an amphibian ancestor approximately 340 million years ago.
    • The first amniotes evolved from their amphibian ancestors approximately 340 million years ago during the Carboniferous period.
    • Synapsids also include therapsids, which were mammal-like reptiles from which mammals evolved.
    • Clade Dinosauria includes birds, which evolved from a branch of dinosaurs.

  • Early Human Evolution

    • Modern humans and chimpanzees evolved from a common hominoid ancestor that diverged approximately 6 million years ago.
    • Several species evolved from the evolutionary branch that includes humans, although our species is the only surviving member.
    • The term hominin (or hominid) is used to refer to those species that evolved after this split of the primate line, thereby designating species that are more closely related to humans than to chimpanzees.
    • The fossil, informally called "Toumai," is a mosaic of primitive and evolved characteristics.

  • Early Homo

    • The Homo genus, to which humans belong, evolved from our close primate relatives, Australopithecus, and is distinguished by cranial size.
    • The genus, estimated to be about 2.3 to 2.5 million years old, appears to have evolved from australopithecine ancestors.
    • The Australopithecus genus evolved in eastern Africa around 4 million years ago before spreading throughout the continent, eventually becoming extinct 2 million years ago.
    • The genus Homo first evolved from australopithecines between 2.3 million to 2.5 million years ago.
    • One of the australopith species eventually evolved into the Homo genus in Africa around 2.4 million years ago.

  • CAM and C4 Photosynthesis

    • Some plants have evolved mechanisms to increase the CO2 concentration in their leaves under hot and dry conditions.
    • Photosynthesis in desert plants has evolved adaptations that conserve water.
    • Desert plants have evolved processes to conserve water and deal with harsh conditions.
    • In addition, cacti have evolved the ability to carry out low levels of photosynthesis without opening stomata at all, a mechanism for surviving extremely dry periods.
    • The harsh conditions of the desert have led plants like these cacti to evolve variations of the light-independent reactions of photosynthesis.
