evolution Flashcards
who was jean baptistic lamarek
-created a line of descent by arranging their similarites and doffferences from older to more recent
-hypthosized that generations of the same species inerhited genes from their ancestors that help that adapt better to their enviorment and allow better survival
Charles Darwin
-travelled around the world for 5 years
-documented his absorvation of the biodiversity of the galapagos islands in plants and animals
created survival of the fittest
what was the purpose of darwins voyage?
-survey the coast of sputh america for the british navy
what was darwins job on the voyage
-observe, record and collect data specifying rocks, minerals plants and mines. he was given the prinicples of geography by lyell to help him calssify rocks
what is natural selection
individuals of a population that inherit genes that allow them to adapt to their enviorment
what is genetic mutation
a radnom chanbge is dna that creates a new allele for better adaption
what is gene flow
migration of individuals to a new enviorment brining new and unique alleles
what is a genetic drift
random population changes that makes certain allleles pass down from one generation to a new one by chance
what is the founder effect?
A change in a gene pool when a few indiviuals starts a new isolation population
bottleneck effect
range of gene distribution resulting from a rapid decrease in population
evidence of fossils
- fossila of the past sepcies can trace the evoluntionary history
evidence of biology
the study of the past and present geographical distribution of different species
evidence from anatomy
- certain organisms have homologous structures, bones, tendons and muscle
evidence from embryos
-showing similar stages of embryotic develpment
evidence of dna
- carries genetic informstion showing how closely related species are
who was george cuvier
-developed the science of paleantology
-hypthosized that past catastriphies destroyed the habittat of some species but not all
charles lyell
-disagreed with george cuvier about the castarophy theory
-hypothesized that similar slow changes in species populations curved over time
uniformarinism
what is phylogeny
sceince that deals with evoluntionary relationships
what is a phylogenic tree
way of showing evoluntionary relationships
what is a clade?
showing an organisms ancestors
what are the kingdoms?
plants, protists, bacteria, archea, eukarya, fungi
what are the domains?
Bacteria, archea, eukarya
what are the taxons
Domain
Kingdom
Phylum
Class
Order
Family
