Species and speciation Samenvattingen, Aantekeningen en Examens

Biodiversity correct answers variability of organisms on earth, generated by evolution through the process speciation Speciation correct answers the formation of a new species species richness correct answers number of species that were or are on earth, Ancient vs current Genetic Variation correct answers Study one species and variation within or between all species Bilogoney Bilogoney correct answers way to organize variation and living things Community composition correct answe...

Convergent vs Divergent Evolution - ANSWER -Divergent: one broad class but because of different features they diverge -Convergent: similar features between 2 different classes Punctuated Equilibrium vs Gradualism - ANSWER -Punctuated: concrete & defined phenotypes -Gradualism: phenotypes gradually evolve Speciation - ANSWER Formation of new species 1) Allopatric: separated by geographical barrier (mountain, ocean, river) -Barrier divides species 1 and species 2 2) Parapatric...

population - ANSWER an interbreeding (sharing genetic information) group of individuals who live in the same geographic area and exist at the same time variability within a species/population (importance) - ANSWER important because: -some genetic variations have advantages over others -natural selection can act on the variation that arises What if populations are separated and can't exchange genes? - ANSWER two processes can occur: 1. genetic divergence 2. speciation genetic diverg...

AP Biology Exam Questions and Answers Graded A+ What are the 2 theories of evolution? Explain each Gradualism- geologic changes result from slow, gradual, continuous process Punctuated Equilibrium- Long period of stasis punctuated by short bursts of significant change. What was Lamarck's theory and why was it wrong? Lamarck = Inheritance of Acquired characteristics- traits acquired during lifetime could be passed on What is natural selection Comptetition for limited resources re...

What is microevolution? - The change in allele frequencies that occurs over time within a population. What is macroevolution? - Major evolutionary changes over time, the origin of new types of organisms from previously existing, but different, ancestral types. What is a species? - A group of populations whose members possess similar anatomical characteristics and have the ability to interbreed. What is allopatric speciation? - The formation of a new species in populations that are geographi...

Micro-evolution - Answer-- a change in an evolution's gene pool over a succession of generations - changes in allele frequencies within populations - often associated with adaptation - can be measured from one generation to the next Macro-evolution - Answer-- major changes in the history of life - origin of new species - generates biological diversity Species - Answer-A population or group of populations whose members have the potential to interbreed with one another in nature to produc...
