While Charles Darwin believed evolution was a slow process, scientists now understand that evolution can happen much faster than previously thought, driven by factors like natural selection, environmental change, and human influence. This article explores the mechanisms and pace of evolution, highlighting how species adapt to changing conditions, even over short timescales.
This article explores the concept of a species, the fundamental unit of taxonomy in biology. It delves into the history of species classification, highlighting the biological species concept and its limitations, and the evolutionary species concept, which emphasizes shared traits and common ancestry. The article also touches upon the ongoing debate about the number of species on Earth and emphasizes the crucial role of species classification in conservation efforts and understanding life’s diversity.
The classification of organisms into species is a dynamic process, constantly evolving with new evidence. This article explores six instances where scientists have had to rethink their understanding of species, from the manta ray to the giraffe, highlighting the ongoing quest to accurately define the diversity of life on Earth.
