By focusing on concepts and big ideas through active learning, students construct a deeper understanding and accep- tance of evolution. The 55-million-year fossil record of horses is one of the most complete records of macroevolution.

What group of animals has the oldest fossil record?
The oldest fossilized evidence of animals has been unearthed in Oman and reveals that tiny sea sponges were abundant 635 million years ago, long before most of the planet's other major animal groups evolved, according to a new analysis.
Is the fossil record a complete record?
The fossil record is incomplete. Of the small proportion of organisms preserved as fossils, only a tiny fraction have been recovered and studied by paleontologists. In some cases the succession of forms over time has been reconstructed in detail.
What was the 1st animal in the world?
Earth's first animal was the ocean-drifting comb jelly, not the simple sponge, according to a new find that has shocked scientists who didn't imagine the earliest critter could be so complex.
What's the first creature on Earth?
A comb jelly. The evolutionary history of the comb jelly has revealed surprising clues about Earth's first animal.
Why is a fossil record not 100 accurate?
The fossil record, however, is quite incomplete. Here's one major reason why: Sediment has to cover an organism's remains in order for the long fossilization process to begin. ... So like the mineralized bones themselves, the fossil record is an incomplete framework that scientists flesh out through additional methods.
What percentage of animals are fossilized?
Fossilisation is so unlikely that scientists estimate that less one-tenth of 1% of all the animal species that have ever lived have become fossils. Far fewer of them have been found.
Why are dinosaur fossils often incomplete?
There are gaps in the fossil record because many early forms of life were soft-bodied. The soft parts of organisms do not form fossils well. This means there is little information about what these organisms looked like. Any traces of fossils that there may have been were likely destroyed by geological activity.
What was the first animal created by God?
Man is the only creature who is created in the image of God. In the genealogies of Genesis, Scripture declares the breath of life of man was transferred to each of Adam's descendants.
What came before dinosaurs?
At the time all Earth's land made up a single continent, Pangea. The age immediately prior to the dinosaurs was called the Permian. Although there were amphibious reptiles, early versions of the dinosaurs, the dominant life form was the trilobite, visually somewhere between a wood louse and an armadillo.
What mammal has been on earth the longest?
Some confirmed sources estimate bowhead whales to have lived at least to 211 years of age, making them the oldest mammals.
What is the first human?
The First Humans
One of the earliest known humans is Homo habilis, or “handy man,” who lived about 2.4 million to 1.4 million years ago in Eastern and Southern Africa.
How did God make animals?
They didn't appear by accident; God created each one with great care. Genesis 1:24-25 says God created the animals, from the beasts of the earth to the creeping insects. Scripture even tells us that the breath of life resides within them (Gen. 7:15).
How did the world start?
When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun.
Is bone a trace fossil?
A fossil is any evidence of prehistoric life that is at least 10,000 years old. The most common fossils are bones and teeth, but footprints and skin impressions fossils as well. ... Body fossils were parts of the organism, such as bones or teeth. Trace fossils include foot impressions, eggs, burrows, and dung.
What is a relative age?
Relative dating is the science of determining the relative order of past events (i.e., the age of an object in comparison to another), without necessarily determining their absolute age (i.e. estimated age).
Can you get DNA from a fossil?
Contamination remains a major problem when working on ancient human material. Ancient pathogen DNA has been successfully retrieved from samples dating to more than 5,000 years old in humans and as long as 17,000 years ago in other species.
