Vocabulary
This term defines the change in a species over time.
What is Evolution?
True or false: Natural selection acts on the population and not the individual.
What is FALSE
Natural Selection acts on the individual AND evolution acts on the population
The name of this Scientist is closely related to evolution by natural selection
Who is Charles Darwin?
Define Speciation.
Emergence of a new species from an ancestral species.
Identify what domain the American black bear belongs to.
What is Eukarya
This term defines a trait's effect on the ability of an individual to reproduce and survive.
What is Natural Selection?
Define genetic drift. What are two types of genetic drift?
Genetic drift: Change in allele frequencies in a population due to chance.
Types:
1. Founder Effect- Can result when a new population is formed by a few individuals.
2. Bottleneck Effect-Can result when a population size is drastically reduced.
What might occur if a species is suddenly introduced into a new habitat?
What is adaptive radiation
Define artificial selection.
Change in phenotype and genotype frequencies in a population that is under human control (animal breeds, agricultural crops, etc).
Identify the evolutionary history of a species.
What is phylogeny
What are all individuals of the same species inhabiting the same geographic area.
What is a Population
To compare species and observe evolution, we can create a ______ ______ using genetic similarities between species .
phylogenetic tree
Who believed unlimited human population growth would lead to poverty/famine?
Who is Thomas Malthus
One of the ways evolution is evaluated is through the remains of organisms preserved in these mineralized structures.
What are fossils.
What is the system for naming species in which two words are used to name an organism?
What is binomial nomenclature
According to the Biological Species Concept, what is a group of individuals that are biologically capable of interbreeding and producing fertile offspring.
What is a Species
This evolutionary process takes place when individuals move between populations. This can increase genetic diversity in a population by adding alleles, but also increase genetic similarity between populations.
Gene Flow (Migration)
Who believed organisms acquired traits and passed on those traits to their offspring?
Who is Jean-Baptiste de Lamarck
What is a diverse kingdom that contains organisms which resemble members of other kingdoms?
What is Protista
What is a group of unicellular/multicellular heterotrophs that absorb nutrients from organic materials?
What is Fungi
This term is used to describe an organisms ability to survive long enough to reproduce. It also describes the number of offspring produced by an individual relative to other members of the population.
What is fitness?
This type of evolution affects certain characteristics of organisms which are not related to survival but whether they are selected to mate.
What is non-random mate selection?
This term is used to describe how species change over time but divergent species share a common ancestor.
What is descent with modification
Which character distinguishes Fungi from Plantae?
a. presence of membrane-bound organelles
b. presence of membrane-bound nucleus
c. cell walls made of chitin
d. multicellular
What is cell walls made of chitin.
Recall the 8 taxa in order from broadest to the most specific.
What is domain, kingdom, phylum, class, order, family, genus, species.
