All of the evidence of living things left behind in Earth´s rock strata, which collectively provide observational evidence for evolution
What is the fossil record?
This harmless mutation to the pigment of the iris leads to eyes of two different colors
What is heterochromia?
These North American pack hunter is the evolutionary ancestor of modern-day dogs
What is the gray wolf OR wolf
These structures may appear in multiple organisms, implying a recent common ancestor.
What are homologies or homologous structures?
This molecule, the foundational unit of genetics, is altered during mutation
What is DNA?
This North American cereal plant has been selectively bred for years to produce large, sweet kernels
What is maize OR corn
An anatomical feature that no longer seems to have a purpose in the current form of an organism of the given species.
What is a vestigial structure?
All humans possess these structures until roughly four weeks of embryonic development
What are tails?
This trait, a result of a mutation from about 500,000 years ago, is the defining characteristic of the polar bear
What is white fur?
This method of artificial selection is often used by dog breeders to produce desired traits in offspring over many generations
What is selective breeding
(DAILY DOUBLE)
This famous, but somewhat obvious, law states that fossils discovered in higher layers of rock strata must be more recent than those discovered in lower layers
What is the law of superposition?
This trait, common in royal bloodlines, is determined by a genetic mutation which makes it impossible to form blood clots
What is hemophilia?
This phenomena, observed by Charles Darwin in the Galapagos Islands, is characterized by the appearance of many new species from a single evolutionary ancestor
What is adaptive radiation?
As seen in the movie GATTACA, this technology allows geneticists to "fix" DNA directly
What is genetic engineering OR gene editing OR gene therapy
This method of dating rocks and fossils allows for highly accurate measurements of age
What is carbon or radiometric dating?
This sugar, found in dairy products, can only be digested by humans with a certain beneficial mutation
What is lactose?
This single plant, a product of natural selection, is evolutionary ancestor of five different leafy vegetables, including cabbage, broccoli, kale, and kohlrabi
What is wild mustard?
