A biological change over time accounts for the diversity of species this diversity ?
The biological change over time is known as evolution, which refers to the process by which species gradually change and adapt to their environments through generations. This change occurs through several mechanisms such as natural selection, genetic mutations, genetic drift, and gene flow.
The diversity of species is a result of these biological changes occurring over millions of years. As species adapt and evolve to their surroundings, they may develop distinct characteristics, behaviors, and genetic traits that differentiate them from their ancestors or other species. This process leads to the emergence of new species and the diversity of life on Earth.
Evolution allows species to exploit different ecological niches, survive in various environments, and fill different roles in ecosystems. It is responsible for the vast array of organisms we see today, ranging from single-celled bacteria to complex multicellular organisms like plants, animals, and fungi.
Overall, the continuous biological change over time through evolution is the primary mechanism responsible for the diversity of species.
