General Study Flashcards
genetic evolution
change in gene (allele) frequency in a breeding population
meiosis
process by which sex cells are produced
crossing over
homologous chromosomes intertwine and exchange DNA
mitosis
ordinary cell division
sexual selection
selection of traits that enhance mating success
balanced polymorphism
alleles maintain a constant frequency in a population over time
random genetic drift
exchange of genetic material through interbreeding
gene flow
exchange of genetic material through interbreeding
speciation
formation of new species
punctuated equilibrium
long periods of stability with occasional evolutionary leaps
paleolithic
old stone age including lower middle and upper
acheulean
lower paleolithic tool tradition associated with H. erectus
archaic H. sapiens
early H. sapiens 300,000 to 28000 BP includes Neandertals
