Biology 8/24 ● Homology: similar structures from a common ancestor with a similar function but best suited with different functions for the individual animal; diverged over time ● analogous : similar function but not homologous ● Insects wings are analogous to birds and bats ○ Adapted through similar environments [convergence] ○ [Fins in sharks and mammals] ● Divergent, convergent, parallel evolution ● Vestigial structures: from an ancestor that are not needed but still remain in or on the body ○ Appendix, erector pili and hair, wisdom teeth, tailbone ● Time is a requirement of evolution ● Convergent: selective pressures from common environments to push different groups of animals to evolve similarly ○ [Phenotypic similarity between marsupials and placental mammals] ● We lost our tail because we are more bipedal ● Hominids: group more closely related to humans than chimps From 23.1 and 23.2 ● Microevolution is the change in allele frequencies in a population through generations ● 3 mechanisms that can cause allele frequency change: genetic drift, natural selection, gene flow ● Only natural selection consistently improves the match between organisms and their environment ● Considerable genetic variation can also be measured at the molecular level of DNA (nucleotide variability) - little of this results in phenotypic variation ● Crossing over in meiosis, slippage in DNA replication, and activities of transposable elements are a potential source of variation ● Gene duplication of large segments on chromosomes may be harmful, but duplication of smaller segments can be beneficial [olfactory receptor genes] ● Individuals in a population must differ genetically for evolution to occur 8/26 ● Microevolution: genetic variation of alleles [genetic level] ● Evolution can’t happen without raw materials, and without variation in a population ● Eastern Africa has a lot of genetic diversity because it is where humans first evolved ● Hardy-W equilibrium - suggests a population is not evolving and the allele frequencies are constant ●

Why people love StudySoup

Steve Martinelli UC Los Angeles

"There's no way I would have passed my Organic Chemistry class this semester without the notes and study guides I got from StudySoup."

Allison Fischer University of Alabama

"I signed up to be an Elite Notetaker with 2 of my sorority sisters this semester. We just posted our notes weekly and were each making over $600 per month. I LOVE StudySoup!"

Jim McGreen Ohio University

"Knowing I can count on the Elite Notetaker in my class allows me to focus on what the professor is saying instead of just scribbling notes the whole time and falling behind."


"Their 'Elite Notetakers' are making over $1,200/month in sales by creating high quality content that helps their classmates in a time of need."
