What is an apical ancestor?
An apical ancestor is the most recent common ancestor of a group of species in a phylogenetic tree. It represents the point where the evolutionary lineage leading to a group of species splits from the rest of the tree.
What is the difference between clan and lineage?
A lineage is a descent group that can demonstrate their common descent from a known apical ancestor. Unilineal lineages can be matrilineal or patrilineal, depending on whether they are traced through mothers or fathers, respectively. Whether matrilineal or patrilineal descent is considered most significant differs from culture to culture. A clan is a descent group that claims common descent from an apical ancestor (but often cannot demonstrate it, or "stipulated descent"). If a clan's apical ancestor is nonhuman, it is called a totem. Examples of clans are found in the Chechen, Chinese, Irish, Japanese, Polish, Scottish, Tlingit, and Somali societies. In the case of the Polish clan, any notion of common ancestry was lost long ago.

What is a group of species that share a common ancestor called?
A group of people who have a common ancestor may be called a "line of descent." In other contexts, a clan or a tribe may have, or claim to have, a common ancestor.Also, it's called "monophyletic" (all members of a designated group are descendants of a common ancestor) members are more closely related to each other than to any member of any other clade.
Does the theory that organisms share a common ancestor is known as common descent?
Yes, that is true.
Is there no evidence of a common ancestor?
There is lots of evidence for a common ancestor but I suggest you look at wikipedia's evidence for common descent or Talk origins 29 evidence for evolution.
What is the definition of ancestral trait?

What relationship would my first cousin's child be to my grandchild?
They would be second cousins, once removed. The descent is from a common ancestor. Thus 1st cousins share a grandparent as a common ancestor. 2nd cousins share a great-grandparent as an ancestor. If the descent from the common ancestor is not an equal number of generations, the inequality is expressed as 'removed' from the oldest generation being compared.
