Evolution & Classification Review: Use the word bank below to complete the following statements or answer the questions. Each word will be used at least once. If a word can be used for more than one question then it appears the respective number of times in the word bank.
- Hypotheses / Theories / Laws are usually most specific in their focus.
- This step in the scientific method is broader, covering several related experiments.
- ______variables are those that the experimenter changes in an experiment.
- ______variables are those that change in response to the changes made by the experimenter.
- This is a definition for______: This trait-based characteristic allows an organism to change within their lifetimes to fit environments when they themselves change.
- This is a definition for______: This behavior-based characteristic allows an organism to change within their lifetimes to fit environments when they themselves change.
- This is a definition for______: Inherited traits that improve an organism’s ability to reproduce.
- This is a definition for______: This characteristic is developed through use and disuse and passed on to offspring.
- The theory for the question above was developed by______.
- Darwin called the process that creates newer, modified descendants of older, related fossils______.
- ______is the process by which populations change over time, sometimes forming new species.
- These are 4 the requirements of evolution, referred to as the “Tenets of Evolution”. List them.
- This Tenet is responsible for ensuring genetic information will be passed on to the next generation by increasing odds of surviving offspring in the organism’s favor.
- This Tenet is a requirement of evolution because there needs to be differences among the members of a population.
- A necessary component of evolution is based the fact that organisms must ______with other members of their population in order to survive.
- This Tenet is responsible for ensuring offspring from successful parents will have similar traits.
- This Tenet is responsible for selecting the best trait for survival from variations that occur in the population.
- When a population becomes better suited to its environment over time it is called______.
- When a person increases their red blood cell count when they travel to higher elevations they undergo ______.
- When a wolf sheds their undercoat in the spring it is called an ______.
- When a beaver builds a dam in a river to create an ecosystem it is called an ______.
- The arm bones of humans, dogs, whales, and bats are built with the same bones, although they have been modified for the organism’s unique needs. These are called______.
- The wings of birds, bats, and butterflies all allow the organisms’ structures to perform the same function (to fly) but they are built quite differently. These are called ______.
- The evolutionary process that creates the features above is called ______.
- These are the 6 categories for evidence in support of evolution.
- ______of different organisms look strikingly similar even though they develop into dramatically different adults.
- ______of similar organisms show a progression of traits in different-aged strata, supporting descent with modification.
- Whales and snakes both have bones that appear in the same area where other animals have legs. These bones, much like human tail bones, are called ______.
- ______of organisms that are found in older strata are simpler than ______found in younger strata.
- The ______defines a species as members of populations that actually or potentially interbreed in nature, not necessarily according to similarity of appearance.
- The closer two organisms are related in evolution, the more similar their ______or _____ sequences are.
- The ______concept defines a species as a group of organisms that can interbreed and have fertile offspring.
- Evolutionary forces include the mutation of genes and ______, which is the movement of alleles into or out of a population.
- In small populations, the frequency of an allele can be greatly changed by a chance event, such as a fire or landslide. This change in allele frequency is called ______.
- If you were to plot the height of everyone in your class on a graph, the values would probably form a hill-shaped curve called a(n) ______.
- Sometimes, individuals prefer to mate with others that live nearby or are of their own phenotype, a situation called ______.
- Evolution at the level of genetic change is called ______.
- When a species fails to produce any more descendants, ______occurs.
- A population in which no genetic change is occurring is in a state of ______.
- (Honors) We prove if genetic change is occurring by determining if ______equilibrium over many generations changes.
- The divergence of multiple lineages into many new species in a specific area and time is called ______.
- The particular combination of all alleles in a population at any one point in time makes up a(n) ______.
- The study of changes in the numbers and types of alleles in populations is called ______.
- A state in which two populations can no longer interbreed to produce future offspring is ______.
- The accumulation of differences between populations is called ______.
- The process of forming new species by evolution from preexisting species is called ______.
- A force that separates one part of population from another is called a ______. This accounts for two or more species arising from one common ancestor.
- A ______illustrates the phylogenic relationship between organisms based upon shared anatomical features.
- The more ______between organisms implies closer phylogeny.
- We can use three types of evidence to determine phylogeny; ______and ______homology.
- The most inclusive taxonomical grouping is ______.
- The most specific taxonomical grouping is ______.
- The scientific name for an organism is based upon ______then ______.
