Oct 19, 2023 · Learn how the theory of evolution by natural selection explains how organisms change over time and how it was proposed by Darwin and Wallace. Explore the evidence, examples, and mechanisms of evolution and the difference between a theory and a hypothesis.
The scientific theory of evolution by natural selection was conceived independently by two British naturalists, Charles Darwin and Alfred Russel Wallace, in the mid-19th century as an explanation for why organisms are adapted to their physical and biological environments.
Learn how Charles Darwin proposed the theory of biological evolution by natural selection, based on his observations of the Galápagos finches and other organisms. Explore the key concepts of evolution, natural selection, and the tree of life.
- Very good! You've correctly deduced an important evolutionary process known as co-evolution. This phenomenon is a key to understanding not just pre...
- From the Homo Sapiens book, Yuval shared a very simple but reasonable concept that standing on 2 legs on the ground will give more broad and wide o...
- Natural selection favors traits that are better for the ORGANISM'S survival and reproduction not for the environment. So actually the inverse would...
- Of course, natural selection just selects for the organisms that will be the most fit (have the most offspring) in a particular environment. One si...
- Natural selection is a mechanism that makes any species - be it a plant, animal, fungus, bacteria, you name it - better adapted to their environmen...
- That's not how science works. You can come up with any ridiculous theory and find as many evidences for it you please. What you should do is to cre...
- Not sure about animal species. In-plant kingdom it occurs and helps the creation of new species or more 'potent' for agriculture, such as watermelo...
- Over time this will happen. This is an important part of evolution called co-evolution, where the evolution of one species affects the evolution of...
- Darwin's concept of natural selection was based on several key observations: -Traits are often heritable. In living organisms, many characteristics...
- There have been other theories but they disagree with observations that the theory of evolution through natural selection explains.
Learn how Darwin transformed our understanding of the living world with his theory of evolution by natural selection. Explore the evidence, the challenges, and the legacy of his revolutionary ideas.
Biological evolution, simply put, is descent with inherited modification. This definition encompasses everything from small-scale evolution (for example, changes in the frequency of different gene versions in a population from one generation to the next) to large-scale evolution (for example, the descent of different species from a shared ancestor over many generations). Evolution helps us to ...
