Watch the 50-million-year evolution of the whale in 1 minute.

We the undersigned, Christian clergy from many different traditions, believe that the timeless truths of the Bible and the discoveries of modern science may comfortably coexist. We believe that the theory of evolution is a foundational scientific truth, one that has stood up to rigorous scrutiny and upon which much of human knowledge and achievement rests. To reject this truth or to treat it as "one theory among others" is to deliberately embrace scientific ignorance and transmit such ignorance to our children. We believe that among God's good gifts are human minds capable of critical thought and that the failure to fully employ this gift is a rejection of the will of our Creator.

Graced with hardy exoskeletons, trilobites preserve some of the oldest evidence of evolutionary innovations common today: heads, mouths, gills, legs and above all eyes. Described in 2017, a three-dimensional trilobite eye fossil preserved enough internal detail to show a work-in-progress compound eye belonging to . Though it had the same general structure as modern bee and dragonfly eyes, the ancient peeper lacked evidence of the tightly packed lenses needed for image formation. Instead, the half-a-billion-year-old arthropod probably used its eyes for little more than movement or obstacle detection. This species was collected from near the base of . A slightly younger (geologically speaking) trilobite specimen showed eye structure closer to that of modern dragonflies.

Two bug species probably made their way to the Hawaiian Islands around the turn of the last century: (a parasitic fly from North America) and (a cricket from Oceania). Like boys everywhere, the male crickets tried to win girlfriends with noise, in their case by rubbing their wings together. But in the presence of the flies, who find the sound as attractive as female crickets do, and whose larvae like to burrow into the males and kill them from the inside, silence turned absolutely golden. Within as few as 20 generations, male crickets on two islands got much quieter, actually losing their chirping abilities. About 50 percent of the males on Oahu, and about 95 percent of the males on Kauai lost the wing structures that make the love songs humans hear as chirps. Not only did entomologists observe these changes over a short time, thanks to the bugs' short lifespans, but they could also see the differences in the wings between the island populations. A study published in 2014 reported that DNA analysis showed different markers in the genomes of the Oahu and Kauai crickets — an example of convergent evolution, where different populations independently evolve similar traits.

During the Cambrian, evolution was rapid and within a few million years the Earth was populated with many animal groups. Fossils found elsewhere indicate that the marine ancestors of New Zealand's ancient land dwelling caterpillar-like were alive at that time. Cambrian deposits in the Cobb Valley, in north-west Nelson of the South Island are the oldest accurately dated geological formations in New Zealand. Some associated sequences occur in small areas in the southwest of Fiordland. The fauna typically consist of Trilobites, Brachiopods, Sponges and Ostracods. Be aware that the rocks in the Cobb Valley are protected and specimens cannot be removed.

Strange Science: What is Evolution?

When wrote , he lamented the incompleteness of the fossil record. His friend disagreed, stating, "The primary and direct evidence in favor of evolution can be furnished only by paleontology. . . . if evolution has taken place, there will its mark be left; if it has not taken place, there will lie its refutation." In a way, both men were right.

To become a fossil, you have to be buried soon after you die — before weather or scavengers destroy your remains. The dirt and mud burying you then have to harden sufficiently to protect what's left of you over thousands or more likely millions of years. At some point, your remains have to find their way to the ground surface and erode out. And there's no guarantee that when your fossilized self sees the sun again that some human — let alone a human who knows or cares about fossils — will happen along at the right moment to find you. In other words, the odds of becoming a fossil are slim. The odds of being found as a fossil are slimmer still.
