A structure that has no use in the organism
Which model of evolution shows change over a relatively short period of time
Nature selects against only harmful traits
a cell can make mistakes when it copies what in the dna
Part 1: Evidence from the Fossil Record Part 2: Evidence from Geographic Distribution of Living Species Part 3: Evidence from Homologous Structures and Vestigial Organs Part 4: Evidence from Embryology
Most of the "higher evolved" animals I can think of have a vestigial structure or two. The most common example given is of the vestigial leg structures that can be found in the back of whales. Ostriches can't fly so i think their wings are considered vestigial. Humans have a vestigial tail bone.
Vestigial StructureA vestigial structure is a structure that appears to no longer have a use in the body.
They don't, vestigial structures are biological structures with no known function that evolved from structures in distant ancestors that used to have a function that is no longer needed.
vestigial
Vestigial.
Humans: the appendix, wisdom teeth, and ear muscles are examples of vestigial structures. Whales: hip bones and hind limb remnants are vestigial structures in whales. Pythons: pelvic spurs, remnants of hind limbs, are vestigial structures in pythons.

Vestigial structure is used in application to structures that are determined genetically but do not have the ancestral function.
Tailbones, tonsils, appendix,
Yes you just did
yeah
vestigial structures.
Vestigial structures are anatomical features that have lost their original function in an organism but are still present. These structures often have similarities to functional structures in related organisms, suggesting a shared evolutionary history. By studying these vestigial structures, scientists can infer how organisms have changed over time through the process of evolution.
