A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation for example, the large muscles of a weightlifter. Any heritable characteristic of an organism that improves its ability to survive and reproduce in its environment. Also used to describe the process of genetic change within a population, as influenced by natural selection.

Until the 18th century, this question was principally in the hands of theologians, who based their calculations on biblical chronology. Bishop James Ussher, a 17th-century Irish cleric, for example, calculated that creation occurred in B. There were many other such estimates, but they invariably resulted in an Earth only a few thousand years old. By the late 18th century, some naturalists had begun to look closely at the ancient rocks of the Earth. They observed that every rock formation, no matter how ancient, appeared to be formed from still older rocks. Comparing these rocks with the products of present erosion, sedimentation, and earth movements, these earliest geologists soon concluded that the time required to form and sculpt the present Earth was immeasurably longer than had previously been thought. By the mid- to late s, geologists, physicists, and chemists were searching for ways to quantify the age of the Earth. Lord Kelvin and Clarence King calculated the length of time required for the Earth to cool from a white-hot liquid state; they eventually settled on 24 million years. There were other estimates but the calculations were hotly disputed because they all were obviously flawed by uncertainties in both the initial assumptions and the data.
This sort of holy forgery and propaganda mill has been in existence almost since the beginning, with a long list of bogus relics and misinterpreted finds. Two weeks ago, Israeli archaeologists uncovered the 8,year-old remains of a prehistoric structure nestled away in the upscale neighborhood of Ramat Aviv. This 8,year-old discovery shows that there were humans in Israel two thousand years before the world was created, according to many Bible literalists. And this find is not alone in its antiquity: By comparison, the Bible and its portrayals constitute much later human artifacts and innovations. Oldest piece of Bible ever found?.

Some things the LDS Church has historically taught are true include the following: The great flood at the time of Noah was a literal event covering the entire earth with water,  the earth's sun "borrows its light from Kolob"  and the earth is only years old. Although many statements abound from LDS authors embracing the search for truth and knowledge no matter the source, when there is a conflict between the LDS position and science, there seems to be two ways of dealing with it: My faith did not come to me through science, and I will not permit so-called science to destroy it. No true scientist will say that we have final, exact answers through scientific research; it is an ongoing, learning process. The Articles of Faith teach us that the Lord "will yet reveal many great and important things pertaining to the Kingdom of God" A of F 1: Some say that God gives to His children as needed, and that it is not important that He gives all of the answers to man because they must work out their own understanding by study and by faith. However, the issue isn't so much that God doesn't reveal all truth, but that so many early church leaders taught and still teach as truth things that are wrong. For a people so interested in truth, and a church that is run by prophets that receive God's word, how could that happen?.
The standard approach to looking at fossils in the geological column is to assume that lower is older. Since the geologic column represents millions of years of Earth's history, then obviously the fossils in each of the layers must be the same age as the layer in which they are found. What is especially interesting is that the fossils do appear to show a progression from the most "simple" of organisms, such as single celled creatures like bacteria, to the most "complex" organisms, such as vertebrates, mammals, and of course humans. This evolutionary progression seems to be clearly demonstrated in that certain kinds of creatures in the upper layers are rarely if ever seen in lower layers.
