This term refers to living things. It includes humans, insects, lizards, plants... the list goes on and on; it even includes single celled life forms.

Within a population of frogs, some are very darkly colored, while others are very lightly colored.
(a)
The naked mole rat has two front teeth that can move individually to pick up food. This trait has been passed genetically by mole rats for many years.
Adaptation
Variety
Genetic Disorder
Organism
The archaeopteryx is an organism that lived long ago. This organism had a jaw like a reptile but also had feathers and perching toes like birds. We are able to know about this species because it left behind imprints of its body, including bones and feather imprints. This imprint is also known as a (a) .
This was the sea ship that Charles Darwin travelled the world on. It helped him reach many land masses in which he was able to study life.
HMS Beagle
HMS Beatle
HMS Golden Retriever
MMS Wildcat
This man studied thousands of life forms to develop a theory of evolution through natural selection. Some of his most famous studies/ observations were conducted on the Galapagos Islands off the coast of Ecuador.
(a)
This man studied thousands of life forms to develop a theory of evolution through natural selection. Some of his most important studies/ observations were conducted in Indonesia. His ideas about adaptation came to him while he was sick with a fever.

Among a population of beetles some are bright green and some are black. In the population the black beetles get devoured rapidly and rarely survive to reproduce. The green beetles match the local leaves so many predators can't find them. Over time there are fewer and fewer black beetles, while the green beetles reproduce and pass on the green trait much more often.
(a)
An archipelago off the coast of South America. This chain of islands provides many examples of how organisms adapt to their specific surroundings. It was a near ideal spot for a certain scientist to develop his ideas about how species change over time.
Galapagos Islands
Indonesia
Hawaii
St Croix
When species survive to a certain point in their lifespan they are able to sexually or asexually create another version of itself. We often see the result of this process in organisms that are smaller than their parents. Ex: Puppies, eggs, babies...
(a)
Male cardinals are usually bright red with black accents and a pointy crest. Females usually look dusty brown with a few red accents.
Sexual Dimorphism
Natural Diversity
Selective Breeding
Sexual Selection
Many organisms contain traits that are actually not that helpful when it comes to survival. However, these traits are used to attract mates. Individuals typically choose certain traits that express healthiness in a partner for reproduction.
(a)
Imagine that an ancient river flowed between members of a species of foxes. One side of the river is marshland with lots of small streams and water sources. The other side is quite hilly with grassy areas covering the majority of land. Over time, the marshland foxes develop webbed feet to move through the marsh and their coat becomes dark brown that blends in with the mud. The grassland foxes develop tough paws with strong claws to dig up grubs and small mammals from the rugged grassland ground. Their coats develop into a wheat colored fur. These two species over time don't even share enough DNA to be considered one species.
Speciation
Convergent Evolution
Coevolution
Foxolution
As time has passed; thousands, millions of years, organisms change through generations. Random genetic variations arise as adaptations in specific environments. As these variations come up, species genetic code and even structure can change drastically. In other words... Descent with modification.
(a)
Wallace was one of the initial founders of this idea. He got to this conclusion by asking, "Why does this species live in this area?" It works to explain the patterns of distribution of species across geographical areas.
