Hace 2 días · evolution, theory in biology postulating that the various types of plants, animals, and other living things on Earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations.
- Francisco Jose Ayala
Through the process of descent with modification, this common ancestor gave rise to the diverse species that we see documented in the fossil record and around us today. Evolution means that we’re all distant cousins: humans and oak trees, hummingbirds and whales.
In the longer term, evolution produces new species through splitting ancestral populations of organisms into new groups that cannot or will not interbreed. These outcomes of evolution are distinguished based on time scale as macroevolution versus microevolution.
Darwin defined evolution as "descent with modification," the idea that species change over time, give rise to new species, and share a common ancestor. The mechanism that Darwin proposed for evolution is natural selection.
- 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.
9 de feb. de 2024 · Evolution is the process by which species adapt over time in response to their changing environment. Use these ideas to teach about the water cycle in your classroom.
27 de abr. de 2022 · Darwin indicated that species could form by the evolution of one species splitting into two, or via a population diverging from its extant ancestor to the point it was a new species. Darwin's...
Where do new species come from? Why do some species go extinct? These are just a few of the questions that can be answered by an understanding of evolution, genetics, and biodiversity.
