Three Postulates of Darwinian Evolution |
|
Definition
1. Struggle for Existence - the ability of a population to expand is infinite, the environments capacity is finite. 2. Variation in Fitness - organisms in populations vary, some traits will prove more advantageous than others. 3. Inheritance of Variation - advantageous traits become more common in generations, disadvantageous traits disappear. |

Occurs when environmental factors change nucleotide so that it is misread during replication. If occurs in gamete, then mutant allele may be transmitted to zygote and into population. Source of new variation in population. |

Definition
Process by which genes pass through one population to that of another through reproduction. Spreads genes through different populations of species. |

Term

Definition
Graduated changes in gene pool slowly accumulated over long periods of time. slowly species A changes into species B. Expected to see this in fossils from millions of years ago, however, there was more evidence towards punctuated equilibrium Best used in evolution of Humans |

After long periods of little or no change an isolation event separates a small population of individuals. With a different gene pool or burst of mutations this isolated group rapidly evolves into a separate species. |

Factors Inhibiting Acceptance of Natural Selection/Evolution |
|
Definition
Lack of Scientific Method - many ideas and concepts were based on singular observations or fanciful accounts of travellers. Nothing was verified or scrutinized on its validity. Modern scientific approach produce and test hypotheses empirically.
Age of Earth - in 1650 the Earth was believed to have been created one afternoon on Oct. 23 4004 BC. Accepted by Church
Separate creation for Humans and Animals - religious doctrine that God created humans separate from animals, made in gods image and more divine than animals.
Fixity of Species - in the 8th century scientists held the belief that everything was created in its original form and was unalterable. |

Population pressure = unconstrained human population growth led to need for permanent leadership (resource managers)
Irrigation = "hydraulic civilizations" support higher population densities, labour intensive irrigation systems controlled and maintained by the state.
Warfare = fighting over land as population grows state evolves from military build-up
Power Struggle = three sources of power: economic, ideological, political. State formation results from competition among chiefs to harness three sources of power and expand their domain. |

Gregor Mendel (1822 - 1884) |
|
Definition
•He was a priest who cared for monastery garden in Switzerland. •Mendel tried to create new and better pea plants using common garden pea (Pisum sativum)
Methods 1) Mendel allowed peas to self-pollinate for several generations. He continued the self-pollinating until he obtained pure breeding plants for the traits he was investigating. He then chose these pure breeding plants as parents for his experiments. He termed them the P generation for parent. 2) He took two P generation plants that had contrasting traits and pollinated them. He termed the offspring of this generation the F1 generation or filial generation. (Filial - ‘brothers and sisters) 3) Finally he allowed the F1 generation to self-pollinate, the offspring of this generation were F2. He counted numbers of offspring with each of parental physical trait(s) in this generation.
•Each individual plant must carry two copies of the ‘factor’ that determines colour and shape. •If plants ‘breed true’ it must mean that the factors are identical, otherwise one will mask the other. • Published his findings in 1866 but raised little interest at the time. This may have been because there was no understanding of genetics at the time and it was not until the 1900's that his work was recognized. |

RNA (Ribonucleic Acid) Molecules |
|
Definition
•Dictate synthesis of proteins that preform a wide variety of functions in the body. •Regulate expression of other genes. •Work with structures in the cell (ribosomes) that are critical for manufacture of proteins. •Transport amino acids to ribosomes for the creation of proteins. |
|
|
Term
|
Definition
•1 or more polypeptide chains. •Polypeptide chains consist of amino acids strung together (ca. 200 - 300, but up to 26,926 amino acids in a single chain of titin [skeletal and cardiac muscles]) •Cell synthesizes RNA from a master blueprint called DNA. •Every function in living cell depends on protein. For example: catalyst of all biochemical reaction is done by enzymes, which contain proteins. Proteins truly basis of life. |

Term
|
Definition
•Synthesis of single strand of RNA into messenger RNA at unwound section of DNA with one of the DNA strands serving as a template. •Result: genetic code in DNA is transferred to mRNA •mRNA carries information to cytoplasm, then protein synthesis occurs via translation. |
|
|
Term
|
Definition
•Genetic information encoded in sequence of three nucleotides termed codons. •Four nucleotides of RNA are: adenine (A), guanine (G), cytosine (C), and uracil (U), which replaces Thymine (T) in DNA template. |

Translation in Protein Production |
|
Definition
•mRNA and tRNA interact with the structure in ribosomes to form protein. •Each amino acid of protein specified by sequence of nucleotides in RNA molecule. •tRNA is information adapter molecule. Direct interface between amino acid sequence of protein and information in mRNA. Therefore it decodes message in mRNA. |

Term
|
Definition
possessing different genes or alleles in corresponding locations on a pair of chromosomes.(Yy) |
|
|
Term
|
Definition
allele of a gene pair that is always phenotypically expressed in heterozygous form. |
|
|
Term
|
Definition
allele phenotypically suppressed in heterozygous form. |
|
|
Term
|
Definition
(sometimes called partial dominance) a heterozygous genotype creates an intermediate phenotype e.g. pink carnations R dominant + R partial dominant = pink carnation. This happens when a dominant red gene competes with a dominant white gene there is a blending. |
|
|
Term
|
Definition
neither phenotype is dominant. Instead individual expresses both phenotype e.g. AB blood type. This happens when there are two recessive genes they share. |
