(To elaborate on my question)I know thata clade is a group of organisms consisting of a common ancestor and all its descendants But doesn't every living thing have a common ancestor?
Please help. Thanks so much!
Answer 1
Yes, every organism known to man apparently has ancestry in common with some other living thing. And yes, a clade is the group comprised by an ancestral species and all its descendants.
In classical taxonomy, there is a fixed set of 'levels' or 'ranks' in the nested hierarchies: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. And this was a useful way of organizing things while we still had little data. But then genomics and computers came along and vastly increased our knowledge of the ancestries of organisms. Eventually, genetics allowed us to discern such a find gradation of common ancestry that it was best to simply let go of the fixed ranks of taxonomy and in stead classify organisms only based on their ancestral relationships as determined by comparative morphology and genomics: cladistics.
There's no trick: your definition of clade says just what a clade is.

Is bacteria a clade?
Bacteria is a clade if you (or anyone else) say it is. However, neither biodiversity nor anything else can be non-contradictory partitioned into clades, so the question does not have any non-contradictory (unambiguous, or objective) answer. Clades are and will always be purely subjective.
What clades has been proposed by plant biologists as the clade that defines the plant kingdom?
The kingdoms Plantae, Streptophyta, and Viridiplantae
Cladistics is a way to separate animals into new species?
Yes and no. Primarily it is for figuring out evolutionary pathways...by grouping animals with similar traits into related families ("clades") it helps us to determine ancestry -- i.e. who evolved from whom...but because it deals with similarities and differences regarding traits, it can also be useful in determining speciation.
What the different between kingdoms and phylogeny?
Kingdom was traditionally the highest level of classification for organisms until recently, when the concept of domains was introduced. There are five kingdoms: Animalia, Plantae, Protista, Fungi and Monera.A phylogeny is the evolutionary history of a species or group of species. They separate organisms by evolutionary relationships (clades), based on comparative cytology and the comparison of DNA, morphological characters, and shared ancestral and derived characters.
What are mushrooms closely related to?
The simple answer is that Fungi are the sister group to animals. However, the proper answer is a bit more complex than that. (It might be best to simply say fungi are closely related to animals.) Animals and Fungi are the major clades forming the superclade Opisthokonta. One of the major synapomorphies uniting this clade is the single, posterior, whiplash flagellum on their motile cells. This feature has been lost in the late diverging branches within the fungal kingdom. It is also missing in some of the early branches that belong neither to the animal or fungal kingdoms. These branches contain protists such as the nucleariids and microsporidia, which are the true sister group to the kingdom Fungi, and choanoflagellates, which are sister to the animal kingdom. These protist groups complicate the question because they can wander and because they are early diverging. Early diverging branches are harder to classify than the so called "crown clades" (i.e. fungi, plants, animals). They form a bush at the the base of these "crown clades." In the most recent taxonomic studies (ie. Katz et al. 2011 doi: 10.1146/annurev-micro-090110-102808 & Katz et al. 2012 doi: 10.1093/sysbio/sys026), fungi and animals do form the superclade Opisthokonta. The problematic protist groups are either left out or in between the two.
