Background records. The name seems so clinical, perhaps even legalistic. We think of background records when we need to hire people, when we’re doing credit checks, and when we’re applying for jobs. But background records cover so much more information and provide so many other useful functions. For example, if you’re researching your family’s genealogy you will find that some background records databases may be very helpful.

Just as an example, many Irish-American families are learning to search backgrounds databases to learn more about Irish immigration records. There are so many databases online now that you can sometimes drill down to the exact group and region you’re looking for when studying your family’s history.

Privacy advocates will advise you, however, that not all databases are very helpful. For example, most if not all genealogical records sites require that living persons give their permission for their personal information to be included in a genealogical database. Otherwise their listings may violate their privacy, which has become a matter of increasing concern.

If you are trying to find close relatives who are still alive your best bet may be to use telephone directories and to look for cousins on sites like Facebook. Some professional directories may also help you find relatives if you know the companies they work for.

Whether the distinctions between the high groups we call Classes and Sub-kingdoms may be accounted for in the same way is a much more difficult question.

The differetiations which separate the mammals, birds, reptiles, and fishes from one another, though extensive, all the same seem of the comparable nature as those which distinguish a mouse from an elephant or a finch from a goose. The vertebrate animals and the insects are so largely diverse in their structure and in the very design of their structure, that dissidents may not unreasonably wonder whether they can all have been descended from a common ancestor by means of the very same laws that explain the specialization of the various species of birds or of reptiles.

Antecedent to Darwin, the vast majority of naturalists held firmly to the belief that species were ontologically extant, and had not been descended from other species by any process fathomable to us. There was, then, no inquiry relating to the ancestry of families, orders, and classes, because the “origin of species” was believed to be an insoluble problem. This has all changed. The entire scientific and literary world consents to, as a matter of common knowledge, the origin of species from other related species by the average process of natural birth.

We might require that a legitimate theory will enable us to perceive and carry out in some detail those changes in the form, structure, and relations of animals and plants which are transformed in short periods of geologic time and that are now going on around us. We may expect our theory to explain adequately most of the small-scale and superficial deviations which distinguish one species from another. And, in conclusion, we may ask that it explain many troubles and to reconcile many incongruities in the overly complex affinities and relations of living things. All this the Darwinian Theory undoubtedly does. It demonstrates that new species are inevitably produced, while the old species become extinct. Evolution theory likewise enables us to understand how the uninterrupted processes of these laws during the long periods is calculated to bring about those greater differences represented by the distinct genera, families, and orders into which all living things are classified by natural scientists.
