Natural Selection
|
The differential reproduction of genotypes; caused by factors in the environment; leads to evolutionary change.
|
|
|
|
Organelles
|
Specialized parts of a cell; literally, small cytoplasmic organs
(endoplasmic reticulum, mitochondria) |

|
|
|
Organ
|
body structures composed of several different tissues grouped in a structural and functional unit.
|
|
|
|
Variables
|
Factors that influence processes.
|
|
|
|
Molecular Clock
|
Accumulated changes in nucleotide sequences of DNA over time.
|
cytochrome c gene is evolving at a steady rate
|
|
|
Emergent Properties
|
The way in which components interact, and often cannot be guessed just by looking at the parts themselves.
|
|
|
|
Phylogenetic Tree
|
The sequence of some genes that have been determined in many organisms and the entire time course of their evolution that is laid out with confidence by tracing the origins of particular nucleotide changes in the gene sequence
|
|
|
|
Inductive Reasoning
|
Logic flows from specific to general. Uses specific observations to construct general scientific principles
|
Francis Bacon, Isaac Newton
|
|
|
Deductive Reasoning
|
Applies General Principles to predict specific results
|
|
|
|
Cell Theory
|
1) All organisms composed of one or more cells
2) heredity and metaboliism occur w/in these cells 3) cells are the smallest living things 4) cells are the basic units of organization of all organisms 5) cells arise only by division of a previously existing cell |
|
|
|
Cells
|
the basic units of life
|
|
|
|
Hypothesis
|
a suggested explanation that accounts for observations
|
|
|
|
Ecosystem
|
A major interacting system that includes organisms and their nonliving environment
|
Population>Species>Community>Ecosystem
|
|
|
Community (biological community)
|
all the populations of different species living together in one place
|
Population>Species>Community>Ecosystem
|
|
|
analogous
|
structures that are similar in function but different in evolutionary origin
|
wing of a bat and wing of a butterfly
|
|
|
Species
|
a kind of organism
|
|
|
|
Artificial Selection
|
the use of selected animals to produce certain characteristics
|
|
|
|
DNA
-Definition -Long Name |
Deoxyribonucleic Acid
the genetic material of all organisms composed of two complementary chains of nucleotides wound in a double helix |
|
|
|
theory
|
Proposed explanation for some natural phenomenon, often based on some general principle
|
|
|
|
homologous
|
from the same evolutionary origin, and with similar structure or function
|
|
|
|
gene
|
a discrete unit of information found within the DNA code
|
|
|
|
molecules
|
atoms that are joined together in clusters
|
|
|
|
genome
|
the entire set of DNA instructions that specifies a cell.
|
|
|
|
tissues
|
groups of similar cells organized into a structural and functional unit
|
|
|
|
Population
|
any group of individuals, usually of a single species, occupying a given area at the same time
