Shows that over time organs that are not needed or not used that a species can live without begin to appear in offspring. ex) some humans are born without their wisdom teeth
Vestigial structures are considered critical evidence of evolution because they are remnants of organs or structures that have lost their original function through the process of evolution. These structures provide insights into an organism's evolutionary history and support the idea that species have changed over time. The presence of vestigial structures suggests that organisms have inherited traits from their ancestors, even if those traits are no longer useful.
Vestigial structures are body parts or organs that have become reduced in size or function due to evolution and no longer serve their original purpose. These structures are remnants of ancestral traits that were once useful but are no longer essential for survival. Examples in humans include the appendix and wisdom teeth.
Scientists use various types of evidence to support evolution, including fossil records showing transitional forms, the distribution of species around the world, comparative anatomy and embryology, genetic similarities among organisms, and observed instances of natural selection. These different lines of evidence provide a strong basis for understanding the process of evolution.
Analogous organs are similar in function and structure but evolved independently in different lineages. This suggests that these organs have adapted to similar environmental pressures, leading to their convergence over time. This supports the idea of evolution, as it demonstrates how organisms can evolve similar traits to better suit their environment.
Jean-Baptiste Lamarck proposed two ideas to explain the mechanism of evolution: the inheritance of acquired traits and the use and disuse of organs. According to Lamarck, organisms could pass on traits they acquired during their lifetime to their offspring, and that the use or disuse of certain organs could lead to changes in those organs over time.

Vestigial structures are anatomical structures of organisms in a species which are considered to have lost much or all of their original function through evolution.
Vestigial organs is the term referring to useless organs left from evolution.
Whales and some other cetaceans have unusable leg bones as a vestigal structure.
Since "vestigial" means an organ that is atrophied or functionless from the process of evolution, out of the list of four structures that are given, the human appendix is that vestigial organ. All of the other organs, especially the "multiple cow stomachs" and the horns of a deer do play an important role to that animal's life.
yes, they are, some people are actually already born without them. It's because of human evolution, since we no longer eat rare foods we don't need that many teeth

The vast majority of scientists support evolution. There is no longer any debate in the scientific community about whether evolution occurs, only the mechanisms in which evolution acts upon is debated.
The theory predicts that evolution will happen and in certain ways. The observed evolution makes this prediction correct. It also defines evolution as happening, and as such is perfect evidence in support of it.
