Experiencing the outdoors can be incredibly enjoyable and invigorating. Nineteenth century geologist Charles Lyell popularized Hutton's view.

Generalists: broad niches (Raccoons) Specialists: narrow niches (Koala) Niche. Things that are analogous are not a result of evolution, whereas things that are homologous are. In the eighteenth century, naturalist Georges-Louis Leclerc Comte de Buffon reintroduced ideas about the evolution of animals and observed that various geographic regions have different plant and animal populations, even when the environments are similar. Experiments have demonstrated that mutations for antibiotic resistance do not arise as a result of antibiotic. One objective of many field biologists includes discovering new, unrecorded species. This phenomenon is called convergent evolution, where similar traits evolve independently in species that do not share a recent common ancestry. However, each organism has adapted these similar features to suit their environment and adapt to environmental changes over time. Sometimes, evolution gives rise to groups of organisms that become tremendously different from each other. Scientists determine the age of fossils and categorize them from all over the world to determine when the organisms lived relative to each other. Large leaves were selected because they allowed the plant to obtain more energy from the sun. After thousands of years, the climate changed, and the area no longer had excess water.
