Darwin developed his theory of evolution by looking at scientific evidence available in the mid-1800s. Since then, the whole field of genetics has developed, adding a powerful independent line of evidence in support of evolution. Genes show how the physical traits of living things are handed down and modified from one generation to the next. By comparing the DNA of many organisms, scientists can map the relationships between species. This map is in remarkable agreement with Darwin’s predictions. The structure of chromosomes and particular genetic sequences point to the conclusion not just of common design, but common descent as well.

This article provides an overview of genomics evidence for common ancestry and hominid population sizes, and briefly discusses the implications of these lines of evidence for scientific concordist approaches to the Genesis narratives.

NASA astronomer Jennifer Wiseman asserts that studying creation can show us the nature of God; science can inform us of what we need to do as stewards of God’s creation; understanding the natural world gives us a deeper knowledge of Jesus Christ; and science can give us a better understanding of ourselves. This essay was presented at the November 2009 Theology of Celebration Workshop.

Many independent measurements have established that the Earth and the universe are billions of years old. Geologists have found annual layers in glaciers that can be counted back 740,000 years. Using the known rate of change in radio-active elements (radiometric dating), some Earth rocks have been shown to be billions of years old, while the oldest solar system rocks are dated at 4.6 billion years. Astronomers use the distance to galaxies and the speed of light to calculate that the light has been traveling for billions of years. The expansion of the universe gives an age for the universe as a whole: 13.7 billion years old. (Updated April 16, 2012)

Fine-tuning refers to the surprising precision of nature’s physical constants, and the beginning state of the Universe. To explain the present state of the universe, even the best scientific theories require that the physical constants of nature and the beginning state of the Universe have extremely precise values.
