Vestigial structures are considered evidence since scientists believe they are structures that were once used by a species ancestors but are no longer needed. They do not impair the organisms in any way, so there is no need for evolution to get rid of them. Vestigial structures are anatomical features that no longer seems to have a function or purpose in the current form of an organism of the given species. Examples are wisdom teeth, the muscles of the ear, the appendix, the tail bone among others in human.
Answer:
(c) their inclusiveness.
Explanation:
The taxonomic classification has eight levels, they go from the more inclusive to the more exclusive.
The eight categories are: <u>Domain</u> which is the most inclusive level, that is to say, that the largest number of individuals are included in this level. There are three domains according to the cells types, and where they live. They are the Eukarya, Bacteria and Archaea. Domains are divided into <u>kingdoms</u>, they are the Plantae, protista, Eubacteria, Archaebacteria, Animalia and Fungi. After kingdoms the <u>Phylum</u> category comes, following Phylum is <u>Class</u>, various classes that are related will form a Phylum. The next category is <u>Order</u>, order is divided into <u>Family,</u> families are broken into <u>Genus</u>, where species are closely related between each other and finally the last category is <u>Especies identifier,</u> in this group there are unique characteristics that will identify a specie. With this classification we can see that we go from global groups to more specifics ones as the classification avances.
