evolution quiz Flashcards
what is the change in populations over time?
evolution
who formed the theory of evolution by natural selection and got credit for it and what is the name of his book called
Charles Darwin; On the origin of species by means of natural selection”
what’s a group of small islands near the equator that Charles Darwin traveled to
Galapagos islands
what is a body structure in a present day organism that no longer serves its original purpose
vestigial
who also proposed a similar theory of evolution but didn’t get much credit for it
Alfred Wallace
what type of structural adaptation where a change in metabolic processes allows a species to survive a toxin
resistance
what body parts that don’t have a common evolutionary origin but are similar in function
analogous
what are structural features with a common/same evolutionary origin
HOMOlogous
who proposed the idea where body parts which are used become larger and those not used become smaller; also proposed acquired traits where traits are passed from a parents lifetime to their offspring
Jean Baptiste Lamark
what era do we live in
holocene
what were the first unicellular organisms to form on earth
bacteria
what rock type are fossils found in
sedimentary
which rock says that the organisms preserved are from warm shallow seas
limestone
who is a scientist that studies fossils
paleontologist
who is a scientist that studies living organisms before they’re hatched or born from 2-8 weeks of age
embryologist
what are the variations of a trait that makes an organisms better suited for their environment
adaptations
what’s the calendar that scientists use to outline the history of life on earth
geologic time scale
whats the evidence of living things or preserved reamins
fossils
what are inherited traits that make an individual diff from other members of the same species
variations
what’s the time period between the birth of one generation and the next
generation time
what uses radioactive elements to determine rock age
radiometric dating
what RAPID change from one species to another occurs
punctuated equilibrim
what do we call it when a species changed to a new species slowly over a long period of time
gradualism
what’s the term used to describe all organisms of a species that have died out
extinct
what term explains when an organism moves from one region to inhabit a diff region
migration
what states younger fossils are in upper rock layers and older fossils are in lower rock layers
law of superposition
created uniformitarianism
Charles lyell
age of a fossil based on the layer of rock compared to the other fossils in diff layers of rock (not exact age)
relative age of a fossil
true age of a fossil determined by radiometric dating
absolute age of a fossil
some populations evolve quickly bc of short generation time
insecticide resistance
