ANT 2011C Exam 1

the study of humans as biological organisms, considered in any evolutionary framework

Physical anthropology

the study of the skeleton

Osteology

the identification of skeletal remains of the means by which the individual died and is a contemporary application of biological anthropology applied to both historical and criminal investigation

Forensic anthropology

the study of nonhuman primates and their anatomy, genetics, behavior, and ecology

primatology

a subfield of biological anthropology dealing with human growth and development, adaptation to environmental extremes and human genetics

human biology

Explain evolution

different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth

Explain Nurture vs. Nature

Nurture is the idea that humans are greatly affected by the people and environment around us while nature says we are born the way we are and nothing impacts that

Explain Neo-Darwinism synthesis

merger of Mendelian genetics with Darwinian evolution that resulted in a unified theory of evolution like genetic variation, natural selection, and particulate (Mendelian) inheritance

Charles Darwin's book "on the origin of species" brought this important perspective to the study of natural history

introduced the scientific theory that populations evolve over the course of generations through a process of natural selection

Why is primatology important to understanding human evolution

Sheds light on why humans are who they are including biologically, culturally, and physically. It can assist in answering questions about human evolution and who we came from which can benefit medical profession, historical, and criminal/ forensic.

A preliminary examination of a phenomenon; the first step of the scientific method

Observation/ hypothesis

this naturalist was the first to use the concept of genus and species to designate types of animals and plants

Carl Linnaeus (taxonomy)

Jean-Baptiste Lamarck suggested an individual could develop a trait in their lifetime and transfer that trait to their offspring. This is called the theory of

inheritance of acquired traits

Darwin referred to the process that many species could emerge from one or a few ancient ones like the spokes of a wheel emerging from the hub as

adaptive radiation

In Darwin's theory of evolution by natural selection, as laid out in On the Origin of Species, observation 3 explains that nature is full of this:

variations

Explain the essential property of science as "self correcting

Each species is always evolving and changing in order to be more fit and survive long enough to reproduce therefore the ones with favorable traits will live to pass on those traits striving for perfection

Explain the importance of the Galapagos Islands for Darwin's understanding of adaptive radiation and natural selection.

Was Darwin's first insight into biogeography; each finch from each island had a different sized beak. Able to see evolution in the act

Explain the concept of fitness

Reproductive success and the ability to survive long enough to reproduce

Explain the 3 pre conditions that must be met for natural selection to work

1. trait must be inherited
2. trait must show variation between individuals
3. filter between the organism and its genetic makeup is the environment, which must exert some pressure

What was the relationship between mutation and natural selection

In order for natural selection to occur a mutation must occur within the organisms offspring giving them an advantage their parents don't have making them more fit and able to reproduce (Natural selection is the process that determines which characteristi

the particulate of inheritance that is passed from generation to generation is called

the gene

somatic cells are simply the cells of the body that are not _________ or sex cells.

gametes

What is the double-stranded heredity material found within the nucleus of the cell

DNA

the assembly of proteins is called _____ ______ that occurs at ribosomes and is based on information carried by messenger RNA

Protein synthesis

If you have a strand of DNA whose base pairs are CGA CGG, what is the base pair segment coded for by the Messenger RNA

GCU GCC

Explain what stem cells are and their special qualities and importance

somatic, unspecialized cells capable of renewing themselves through cell division and they can be induced to become tissue- or organ-specific cells with special function

Briefly explain protein synthesis

Occurs in ribosomes on rough ER, mRNA brings in information from DNA in nucleus then it is translated to tRNA and codons are translated to amino acids which form polypeptides

Explain the difference between a polypeptide and a codon

A polypeptide is a group of amino acids, a codon is a group of base segments that can translate to an amino acid ex: CGG

What is the basic difference in cell division and end result between meiosis and mitosis

Mitosis forms 2 diploid daughter cells with identical DNA and happens in somatic cells & Meiosis forms 4 haploid daughter cells with half the DNA and occurs in gametes/sex cells

Why is mitochondria DNA important in the recovery of ancient DNA

There are thousands of copies of mitochondrial DNA and is easy to amplify

the blood system ______ is a good example of the genotype and phenotype

ABO

If an individual has the phenotypic blood type B, what are the possible genotypes?

BB or BO

Obesity provides a complex example of the relationship between genes and the

environment

The best known x-linked disorder

hemophilia

Francis Galton was responsible for pioneering a movement called _____ that ultimately had serious and long standing negative consequences

Eugenics

What is the difference between a genotype and phenotype

A genotype are the genes that are in the DNA but the phenotype is the physical traits

What is the difference between structural genes and regulatory genes?

Structural genes are genes that contain the information to make a protein while regulatory genes guide the expression of structural genes without coding for a protein themselves

What did Mendel's experimentation on the garden pea show us about the nature of genetic transmission

Each trait is passed on individually as explained in his laws of segregation and independent assortment

Compare and contrast polygenic traits and pleiotropy

Pleiotropy is multiple phenotypes expressed for one genotype while a polygenic trait is one phenotype for one genotype

Briefly explain Mendel's law of segregation and law of independent assortment

Law of Seg: the alleles on a gene for a chromosome will segregate independently
Law of Ind. Ass.: each gene is separate of the chromosomes and are independently assorted
