Macroevolution Study guides, Class notes & Summaries

What is biological evolution? - Answer-Heritable change in a population across many generations. What is the difference between microevolution and macroevolution? - Answer-Microevolution is on a small scale. It is a change in a single gene. Macroevolution is on a large scale and results in the formation of a new species. What is a scientific theory (definition)? - Answer-A well-tested concept that explains a wide range of observations. What is catastrophism? - Answer-The idea presented by ...

Microevolution - correct answer change in gene frequency in a population Macroevolution - correct answer evolution builds overtime; looked at from outside the species level Meiosis - correct answer cell division in which alleles are spread apart; produces gametes, four haploid cells Mitosis - correct answer "basic" eukaryotic division; cell division that makes identical copies; duplicated DNA is split Binary Fission - correct answer happens in prokaryotes; divides into tw...

aa - Answer-albinism heterozygous parents - Answer-25% chance of offspring having recessive disease population - Answer-group of individuals of same species living in the same area population genetics - Answer-study of all alleles in a population gene pool - Answer-all the alleles in a population gene flow - Answer-the movement of alleles between populations. usually caused by migration and mating phenotype frequency - Answer-based on observaitons -how common is the trait -PKU disease ...

Lecture notes covering the topic of Macroevolution

Hardy-Weinberg equilibrium principle states Answer allele frequencies in a population will not change from generation to generation; if allele frequencies are p and q, genotype frequencies will be p^2, 2pq, q^2 mechanisms of evolution Answer drift, selection, migration, mutation population genetics Answer integrates natural selection with Mendelian genetics evolution is ______ in a population Answer change in allele frequency species are not immutable Answer microevolution lineage...

GMO (genetically modified organism) - An organism whose DNA has been deliberately altered. Made possible by Recombinant DNA technology. Evolution - Change in a population or species over generations Microevolution - Change in allele frequencies in a population over generations. Macroevolution - Evolution at or above the species level Charles Darwin - Father of evolution Darwin's Theory of Evolution - Species living today descended from a single ancestral species. Two main components are ...

Anthropology 101: Chapter 3 Neo-Darwinism - correct answer Combination of ideas with natural selection (Darwin) and heredity (Mendel) Race becomes a meaningless concept Reproductive community of populations that occupies a specific NICHE in nature Microevolution - correct answer Short-term evolutionary changes SINGLE SPECIES SHORT STRETCHES of ECOLOGICAL TIME Macroevolution - correct answer Long-term evolutionary changes At or above the species level LONG STRETCHES of GE...

Evolution - Answer-Change in the inherited traits in a population of organisms over time. Ecology - Answer-How organisms interact with each other and the environment Natural selection - Answer-A natural process resulting in the evolution of organisms best adapted to the environment. Theory of evolution - Answer-Created by Charles Darwin, organisms pass on their DNA to their offspring; avoiding close relatives for more variety. Microeveolution - Answer-The change in the inherited traits in ...
