History of Life on Earth

Those who advocate for naturalism assume uniformitarianism – that no process has ever occurred on Earth that is not happening today. When researchers find a fossil, they assume that the preservation of that fossil was accomplished by the same natural processes that are preserving biological material today. In the past, some in the scientific community have challenged the discovery of an asteroid strike, which apparently caused the extinction of the dinosaurs. They rejected it because it would violate uniformitarianism. However, some discoveries don’t fit uniformitarianism, and various theories of the history of life on Earth change with new evidence.

Reconstruction of the chromosomes of a woolly mammoth found in Siberian permafrost has given new information. This animal was quickly freeze-dried, preserving the 3-D structure of ancient chromosomes containing DNA. Dehydrated chromatin was preserved in a unique state resembling the molecules in glass.

This remarkable find allowed scientists to determine that the woolly mammoth had 28 pairs of chromosomes. Modern elephants also have 28 chromosome pairs, so researchers can discover which genes regulating hair follicle development were active in key positions, explaining why the mammoths were woolly and modern elephants are not. This 52,000 year old specimen opens a whole new area of study of the history of life on Earth.

Another message of the discovery of this specimen is that it re-opens the discussion of whether uniformitarianism is a valid assumption to understand the history of life on Earth.

In our personal trips to Alaska, we have seen other specimens of animals frozen in the permafrost. In the 1970s, gold miners discovered frozen bison, one called Blue Babe, because of its staining from minerals in the area. This specimen was put on display in the University of Alaska Museum in 1979. It had claw marks, which were believed to be from a lion. In 2012, another bison specimen named Bison Bob was discovered, and other animals were found frozen in the same layers of permafrost.

The Bible tells us that events have happened in the past that are not uniformitarian. They are rare, but those events are a clear indicator that naturalism and uniformitarianism are not good assumptions in building an understanding of Earth’s history.

Extinction of Plant and Animal Species

Near the end of 2023, the U.S. Fish and Wildlife Service removed 21 species from the Endangered Species Act because they have become extinct. What causes the extinction of plant and animal species?

Many factors lead to extinctions. Dr. Hugh Ross says the fossil record indicates that half of the mammal species that existed at the time of Adam and Eve are now extinct. Human activities that can endanger species include habitat destruction, introduction of invasive species, and introduction of diseases. Of course, animals can endanger people in various ways, including introducing diseases.

Humans have endangered plant species by introducing invasive plants. Plants used for decorative purposes can become invasive. Examples are English holly and the tree of heaven. Some plants that have become invasive were introduced to serve a purpose, such as controlling erosion. An example is the kudzu plant.

At other times, humans have caused extinction by killing large numbers of a species such as the passenger pigeon. Because of hunting and habitat destruction, the dodo bird became extinct within less than a century of its discovery. Humans caused the extinction of the great auk by foolish vandalism. Today, poachers are endangering the rhinoceros by killing them for no good reason. By contrast, human efforts rescued the California condor after it became extinct in the wild.

Woolly mammoths existed alongside early humans, and some scientists say they were essential for the survival of humans in some areas. People used them for food and their skins for protection from the elements. Their bones became tools, building materials, and even musical instruments. These large animals also kept plant vegetation under control while spreading their seeds. We can not always determine the cause of the extinction of plant and animal species, and that is the case with woolly mammoths.

The extinction of the dinosaurs occurred before humans were on the scene. That is good because humans and dinosaurs could not coexist on the land or at the same atmospheric oxygen level. God used them to prepare Earth for humans, and He orchestrated their extinction before He placed Adam and Eve in the garden.

As we look at the extinction of plant and animal species, we learn some essential facts. From the beginning, God had a plan for life as He prepared this planet for us to be here. He gave the first humans the responsibility to take care of the Earth, but we have not done a very good job. Finally, God is still giving us a chance to do better, and we have had some successes. Serving God involves serving others and caring for what God has given us for human flourishing. We can only do that when we submit to His plan for our lives.

The Purpose for the Woolly Mammoth

Often when we see fossil evidence of extinct animals, we wonder what purpose that animal served. For example, the giant plant-eating dinosaurs not only pruned the fast-growing plants of the world in which they lived, but they also spread the plant seeds and fertilized the ground where the plants grew. So what was the purpose for the woolly mammoth?

Russian researchers have found that woolly mammoths played a significant role in shaping the Siberian tundra in the ancient past. Today we see that massive amounts of moss dominate the terrain and causing a build-up of carbon dioxide. Woolly mammoths pulverized the moss, clearing the way for grass to spring up. They enriched the soil for the grass to grow, and the grass stopped soil erosion and took in carbon dioxide.

An American company wants to reconstruct the woolly mammoth’s genome and create herds of woolly mammoths to repeat what happened in the past. That company believes they can increase grass growth and create a whole industry based on herds of woolly mammoths.

This scenario sounds similar to the theme of the movie Jurassic Park. Unfortunately, we don’t have good information about what woolly mammoths were like, how they lived, and what diseases they carried. God had a purpose for woolly mammoths, and the research by the Russian scientists tells how that system worked in the past. When humans try to duplicate what God did, they usually do more damage than good.
