why humans, animals, plants and microorganisms evolved?​

Answer:

HUMANS

Over time, genetic change can alter a species' overall way of life, such as what it eats, how it grows, and where it can live. Human evolution took place as new genetic variations in early ancestor populations favored new abilities to adapt to environmental change and so altered the human way of life.

ANIMALS

If there is a major change to the environment, such as new predators, human interference, an invasive species or rising temperatures, then the species will adapt and evolve. Natural selection will favor the animals that are better suited for surviving the new environment.

PLANTS

Botanists now believe that plants evolved from the algae; the development of the plant kingdom may have resulted from evolutionary changes that occurred when photosynthetic multicellular organisms invaded the continents.

MICROORGANISMS

Bacterial evolution refers to the heritable genetic changes that a bacterium accumulates during its life time, which can arise from adaptations in response to environmental changes or the immune response of the host. Because of their short generation times and large population sizes, bacteria can evolve rapidly.

Explanation:

EVOLUTIONS OF HUMANS

Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family, which includes the great apes.

EVOLUTIONS OF ANIMALS

Genetic data suggest that multicellular animals evolved around 1000 million years ago; this is supported by fossil embryos from rocks in China that date back 600 million years.

EVOLUTIONS OF PLANTS

The evolution of plants has resulted in a wide range of complexity, from the earliest algal mats, through multicellular marine and freshwater green algae, terrestrial bryophytes, lycopods and ferns, to the complex gymnosperms and angiosperms of today.

EVOLUTIONS OF MICROORGANISMS

Bacteria have been the dominant forms of life on Earth for the past 3.5 billion years. They rapidly evolve, constantly changing their genetic architecture through horizontal DNA transfer and other mechanisms. Consequently, it can be difficult to define individual species and determine how they are related.

Evolution happened because of the diversity of the energy resources available for life to thrive, diversity of envoronmental conditions, and because of mutations happening every time an organism reproduces, enabling adaptation to such a broad range of diverse conditions and opportunities. If no mutation (including both genetic and epigenetic mutations) would have ever occurred, evolution would have never happened.
