BIOL 1010 Final Exam Questions and
All Correct Answers 2025-2026
Updated.
soapberry bugs - Answer beak size was favored depending on the available food source, over
time the species evolved to have shorter beaks
directional selection
favored characteristics changed with environment
vertebrate forelimbs - Answer humans, cats, whales, and bats all have similar bone structure
in their forelimbs (homologous structures)
prairie chickens - Answer bottleneck effect
prairie chickens' habitats were fragmented and reduced due to agricultural expansion
which caused a severe population decline
and decreased genetic diversity
sickle-cell anemia - Answer polymorphism & heterozygote advantage
people with one sickle cell gene and one normal gene are protected from severe malaria and
having two sickle cell genes can cause sickle cell anemia
mules - Answer hybrid infertility
horse + donkey
mules are infertile
linnean classification - Answer Kingdom, Phylum, Class, Order, Family, Genus, Species
allele notation - Answer dominant alleles (A)
recessive alleles (a)
or C^r vs. C^w
geological time scale - Answer eons, eras, periods
name and order of eras within phanerozoic eon - Answer 1. paleozoic era (oldest)
2. mesozoic
, 3. cenozoic (most recent)
position of permian period and its mass extinction event - Answer final period of paleozoic
era
permian triassic extinction event (the great dying) caused by volcanic action
position of cretaceous period and its mass extinction event - Answer final period of mesozioc
era
crestacaous paleogene extinction event (large asteroid)
biological evolution - Answer change in biological entities over time/generations
carolus linnaeus - Answer developed taxonomy/biological classification
paleontology - Answer scientific study of fossils
fossils - Answer bones, rocks, etc.
many extinct species preserved as fossils
deeper layer of rocks = further bac in history
jean baptiste lamarck - Answer proposed that new species arise by modification of existing
species
2 key points from darwin's origin of species - Answer 1. pattern of evolution
2. process of evolution
pattern of evolution - Answer living things are united in one branching tree of evolution
process of evolution - Answer evolution occurs primarily because of the action of natural
selection
3 components of natural selection - Answer 1. heritable variation
2. excess production
3. differential success
heritable variation - Answer individuals in a population are born with different traits
