What is camouflage.
100
Identify this.
What is a fossil
100
Identify this.
What is an embryo?
100
A change in the DNA of an organism. Could be beneficial, neutral, or harmful.
What are mutations?
100
The structures used for senses. It changes over time and can show how a group of organisms changes as it adapts to many different environments over its evolutionary history.
What is the skull?
200
Chimpanzees use twigs to "fish" for termites.
What is a learned behavioral adaptation?
200
The permanent disappearance of a species from Earth.
What is extinction?
200
A developmental stage wherein common ancestry is easily identified between species.
What is an embryonic stage?
200
A trait or mutation that helps an organism survive and reproduce in its environment.
What is an adaptation?
200
This structure can show the transition from land environment to ocean environment to air environment
What are limbs? (Hands, Feet, & Legs)
300
Fat and happy Grizzly bears move to the cave in the winter time to hibernate and have cubs.
What is an instinctive behavioral adaptations?
300
A compilation of all evidence of how the Earth and life have changed since it was a molten ball of rock 4.54 billion years ago till today.
What is the geologic time scale?
300
Name a species that shares common ancestry with humans?
What is any vertebrate?
300
The process by which an organism's survival is determined by its ability to adapt to its environment long enough to pass on beneficial traits to its offspring.
What is natural selection?
300
Different structures in organisms that serve the same function such as bat wings, butterfly wings, and bird wings.
What are analogous structures?
400
Venom in the fangs or poison in the tissues.
What is physical (chemical) adaptation?
400
Distinctive fossil used to compare the relative ages of rocks.
What are index fossils?
400
At which point do the embryos in the image below become identifiable?
What is the 3rd stage?
400
What is this picture representing.
What are selective pressures?
400
Structures that used to have a function in an ancestor but do not in the modern organism, such as hips and legs on pythons and boas.
What are vestigial structures?
500
The young male cuttlefish disguises itself as a female cuttlefish.
What is mimicry?
500
Organizing layers of rock by logic, fossils, and observations to determine the order of events.
What is relative age dating?
500
Embryology is used to identify common ancestry, homologous structures, and vestigial structures left over to support this theory.
What is the theory of evolution via natural selection?
500
Homologous structures, vestigial structures, analogous structures, fossil record, DNA, adaptations, and embryology.
What are the evidences that species have evolved (changed over time)?
500
Similar structures in organisms but with a different function, such as whale flippers, cat legs and elephant legs.
What are homologous structures?
