evolutionary processes that occur within a species, short term changes in the frequency of genes (a few generations)
Most common in Ashkenazi (European) Jews, caused by an abnormal form of an enzyme that as ganglioside GM2. When this substance builds up, it is toxic to nerve cells and death usually occurs before 5 years of age
Tay Sachs Disease
The study of human kind in a cross-cultural context. Anthropology includes subfields cultural anthro, linguistics, anthro, archaeology, and bio anthro
study of language.
the study of the material cultures of past peoples.
the objects, from tools to art, left by earlier generations of people
including or involving all of something, especially all of somebody's physical, mental, or social conditions, not just physical systems, in the treatment of illness
during gamete foundation, segregating pairs of units factos assort independently of each other
independent assortment
when parental alleles combine (when sperm cell units with the egg cell in gametes)to produce offspring, they retain their original characteristics
Particulate Inheritance
the study of the skeleton
during the formation of gametes, the paired unit factors separate, or segregate randomly so each sexcell receives one or the other with equal likelihood. It reflects the fact that in diploidorganisms, the chromosomes in a pair segregate randomly into sex cells during meiosis
laws of segregation
the study of the fossil record of ancestral humans and their primate skin
was based on two assumptions. Each parent contributes equally to the offpsring, and their contributions are halved at each succesive generation
blending theory
change in the frequency of a gene or trait in a population over multiple generations
differential reproductive success over multiple generations.
Natural selection
having the same allele (gene) at the loci for a gene on both members of a pair of homologous chromosomes
theory that there have been multiple creations interspersed by great natural disasters such as Noah's flood
having two different alleles (genes) at the loci for a gene on a pair of homologous chromosomes
theory that the same gradual geological process we observe today was operating in the past
in a diploid organisms, an allele that is expressed when present on only one of a pair of homologous chromosomes
each living form possessed an absolutely fixed essence that could not be altered and that life was arranged in an orderly, hierachical ladder, with humans at the very top
Immutability of Species
in a diploid organism refers to an alles that must be present in two copies, (homozygous) in order to be expressed
everything remains fixed and unchanged. All forms of life created once and only once. Their presence on this planet will never change--remains fixed. Created perfectly by the master designer.
Fixity of Species
An observable or measurable feature of an organism. Phenotype can be anatomical, biochemical, or behavorial
Linnaean naming system for all organism. Phenotypes can be anatomical, biochemical, or behavorial
Linnaean naming system for all organisms, consisting of a genus and species label
Bionomial Nomenclature
The genetic makeup of an individual. Genotype can refer to the entire genetic complement or more narrowly to the alleles present at a specific locus on two homologous chromosomes
Aristotle's idea that all organisms existed in a hierachical ladder of sorts, with people at the top rung, was very much in place as both a natural philosophy and legal code
Great Chain of Being=Scale of Being
the sex cells: sperm in males and eggs (or ova) in females
Gamete=Sex Cell
The fundamental unit of heredity. Consists of a sequence of DNA bases that carries the information for synthesizing a protein (or polypeptide) and occupies a specific chromosomal locus
alternative versions of a gene. Different alleles are distingusihed from one another by their different effects on the phenotypic expression of the same gene.
Inherited abnormality of hemoglobin (carries oxygen in red blood cells). Usually causes early death (before you can reproduce) Often incorrectly referred to as "black person's disease"
Sickle Cell Anemia
different rates of reproduction among the individuals. Some individuals have a better chance of surviving and reproducing, passing on their beneficial traits that will be represented in the population
differential fertility
differnt in the death rate--weeding out the misfits. Individuals who are not adapted to their enviroment have a greater chance of dying early. Not living to reproductive age. Will their traits be represetned in the next generations? NO!
differential mortality
population evolves via natural selection
industrial melanism
heterozygote selected for contributing their alleles (both) to next generation-explains why both maintained in the population. Both alleles are being selected for
Balanced Polymorphism
the study of human remains applied to a legal context
forensic anthropology
the difference among humans such as physical and genetic traits...eye color, etc. Examines the distribution of traits. Helps us to avoid racism and makes up more understanding of human diversity
human variation.
