What is adaptive radiation?

What is adaptive radiation?

• A. Separation of species into distinct species
• B. Ancestral species evolving into various species
• C. Species developing similar traits in similar environments
• D. Organism's response to environmental changes

Answer: (B)

Adaptive radiation is a process in which an ancestral species rapidly diversifies into a wide variety of forms to adapt to different environments or ecological niches. This typically occurs when populations of a species become isolated from one another and face different selective pressures, which leads to the evolution of distinct traits that are suited for those specific conditions. When an ancestral species encounters new opportunities, such as colonizing a new habitat with different resources or challenges, natural selection drives the evolution of multiple species from that common ancestor, each adapted to thrive in their unique environment. This phenomenon is often observed following mass extinctions or when species invade new areas, as seen in examples like Darwin's finches, where a single ancestral species evolved into several different species, each adapted to specific roles within their ecosystems. The other options describe different biological concepts, such as speciation and convergent evolution, which do not specifically capture the essence of adaptive radiation. While the separation of species can lead to distinct species, it does not necessarily involve the rapid diversification from a common ancestor into many forms. Similarly, species developing similar traits in similar environments refers to convergent evolution, which is distinct from the idea of a singular ancestral species branching out. The general response of organisms to environmental changes is broader and does
