All the great-grandkids in the family who are two generations away are "second cousins" to one another, all the great-great-grandkids are "third cousins" to each other, etc.
It's sort of like finding a common denominator--you start with the broadest set of "cousins" you can find in a shared generation, and then count off how much one side is out of balance. As an example, if you and I are in the same generation as second cousins, then you're a second cousin "once-removed" to my kids, since you're in a different generation than they are, by one.
I'm the same thing to your kids, for the same reason in reverse. Our collective set of kids would all be "third cousins" to one another, since they're all once again evenly distant from the great-grandparents that you and I share, bringing the whole thing back into balance.
Hope that's not too complicated--it's actually the type of thing you could explain in 2 secs with some diagrams. Your sister's kids are related to her by 0. Your niece's son is related to her by 0. Your son is related to you by 0. He's related to her son by his relation to her 0. Or equivalently, by your relation to your niece's son, 0.

Hamilton, your inclusive fitness is your own reproductive success plus the reproductive success of your kin times the coefficient of your relation to those kin.
So your niece having a child increases your fitness one-fourth as much as you having a child; equally, if she has four kids, that increases your inclusive fitness as much as you having one kid of your own.

His second wife also insisted on naming her son Japhet after his father. The boys were only about seven years apart in age.
Although currently the two terms are frequently used interchangeably, there is a difference between a genealogy and a family history. A genealogy starts with one ancestor, most often the original immigrant to the United States, and traces all his descendants to the present time.
If that ancestor arrived on these shores in colonial times, you can imagine the hundreds and hundreds of descendants he now probably has and what a mammoth task it must be to find even half of them! A family history starts with yourself or your children and moves back through your two parents, four grandparents, eight great-grandparents, sixteen great-great-grandparents, thirtytwo great-grandparents, etc.
Most genealogy courses offered today concentrate mostly on techniques for a family history rather than a genealogy.

However, many of the methods can be used for both. While this is handy for common speech, it can be frustrating to genealogist or family history researcher.
