25
Comparing bits of DNA to identify unknown species or fix categorization mistakes.
DNA Barcoding
26
Divides all living things into the most generalized categories.
Kingdom
27
Groups organized by evolutionary history and body plan sharing key characteristics but different lineage.
Phylum
28
Growth that continues over a lifetime.
Indeterminate Growth
29
Growth that alternates between fast or slow or no growth, over a lifetime.
Periodic Growth
30
Growth that occurs and then stops when it has reached a maximum size.
Predetermined Growth
31
Growing bigger by making individual cells bigger.
Eutely
32
Growing a larger body out of cells that have been set-aside. In the larval form of a creature there are cells with a predetermined amount of growth, as well as a few that take over once the originals die. The ball of set-aside cells then develop into the many cell types needed to create the adult form.
Maximal Indirect Development
33
Growth that occurs by adding complete, individual clones to an original form.
Colonial Growth
34
Distantly related creatures that evolved similar traits.
Convergent Evolution
35
A type of convergent evolution in which non-crab like animals evolve into crab-like creatures because of the huge evolutionary benefits.
Carcinization
36
The period between 359.2 and 299 million years ago, and the second to last period in the Paleozoic era.
Carboniferous Period
37
Derived from Greek roots meaning “ancient life” this era happened from 541 to 252 million years ago.
Paleozoic Era
38
The period between 145.5 and 65.5 million years ago, and the final segment of the Mesozoic era.
Cretaceous Period
39
Derived from Greek roots meaning “middle life” this era lasted 252-66 million years ago.
Mesozoic Era
40
The period between 199.6 and 145.5 million years ago.
Jurassic Period
41
Having a raised chance of surviving to pass on genes.
Evolutionary Fitness
42
Evolving a head.
Cephalization
43
Evolving to not have a head.
Decephalization
44
A structure that collects the sense organs needed to perceive the world, the mouth, and nerve cells that coordinate the structure in front of the animal, where they can react to danger and other stimuli.
Head
45
Creatures that are symmetrical and have symmetrical halves.
Bilaterians
46
The property of being symmetrical and divisible into halves.
Bilateral Symmetry
47
Symmetry around a central point.
Radial symmetry
48
A flexible rod that supports a body as an embryo and sometimes as an adult, but usually develops into a vertebral column in adulthood.
Notochord
49
Creatures that have a vertebral column.
Vertebrates
50
Creatures that do not have a vertebral column.

51
A framework that shapes, supports and protects soft tissue.
Skeleton
52
An internal support structure made of mineralized tissues.
Endoskeleton
53
A type of mineral compound containing largely calcium and phosphorus.

72
A creature that lives off another species as a main source of food.
Parasitism
73
A waste product found in blood created when a body breaks down purines. In controlled amounts it can aid in immune receptivity for humans. Excreted by birds and reptiles and unusually by humans since other mammals convert it to allantoin.
Uric Acid
74
Protiens that enter the body via the digestive tract metabolize into uric acid. They are also a naturally occurring chemical that is beneficial to many different bodily needs.
Purines
75
A substance formed by ammonia being converted into something less toxic. Amino acids to ammonia to this. Mammals excrete this.
Urea
76
A gas made up of nitrogen and hydrogen. One way it is produced is through the breakdown of amino acids in a body. Fish, alligators and crocodiles excrete this.
Ammonia
77
An insoluble substance that makes up plant cell walls and plant fiber. Made of glucose monomers.
Cellulose
78
The network of nerve cells that transmit messages through the body.
Nervous System
79
Organs, or groups of tissue or cells that all do the same thing, that are made up of big bunches of nerve cells called neurons.
Brains
80
Sends and receives information from other cells using electrical signals and processes the information in order to respond environmentally.
Neurons
81
The tail-like feature of a nerve that passes along electrical signals.
Axon
82
The nucleus-housing central part of a nerve that provides structure, takes in nutrients, and carries out specialized functions.
Cell Body/Soma
83
Groups of neurons that work together.
Ganglia
84
Dense tissues that protect and stabilize the brain and spinal cord to the surrounding bones.
