a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus and denoted by a Latin binomial.

the change in heritable traits within a population over successive generations,

the remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock

the process of changing, adjusting, or modifying to suit new conditions, environments, or purposes

a well-substantiated, comprehensive explanation of natural phenomena, built upon repeated testing, observation, and evidence.

a fundamental mechanism of evolution where organisms better adapted to their environment tend to survive and produce more offspring.

an interaction between organisms (same or different species) striving for the same limited resources—such as food, water, light, space, or mates—which often reduces the fitness of one or both parties

a mode of natural selection where individuals with certain traits are more likely to obtain mates and reproduce

the process where two or more species reciprocally affect each other’s evolution through close ecological interactions

the total collection of all discovered fossils—preserved remains, imprints, or traces of organisms—and their placement within the Earth's rock layers

the earliest stage of development in a multicellular organism, beginning after fertilization of an egg cell

Homologous structures

body parts or traits in different species that share a common evolutionary ancestor, even if they now serve different functions.

the permanent disappearance of a species, subspecies, or group of organisms, occurring when the last individual dies

physical remnants of body parts that had a significant function in an ancestor species but have become functionless, reduced, or repurposed in the modern species

a technique in evolutionary biology that uses the relatively constant rate of mutation in DNA or protein sequences to estimate the timing of evolutionary events

the science of determining the relative chronological order of past events, fossils, or rock layers without determining their absolute age

the process of determining a specific, numerical age of fossils, organic remains, or geological layers

Question	Answer
Species	a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus and denoted by a Latin binomial.
Evolution	the change in heritable traits within a population over successive generations,
Fossil	the remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock
Adaptation	the process of changing, adjusting, or modifying to suit new conditions, environments, or purposes
Scientific theory	a well-substantiated, comprehensive explanation of natural phenomena, built upon repeated testing, observation, and evidence.
Natural selection	a fundamental mechanism of evolution where organisms better adapted to their environment tend to survive and produce more offspring.
Competition	an interaction between organisms (same or different species) striving for the same limited resources—such as food, water, light, space, or mates—which often reduces the fitness of one or both parties
Sexual selection	a mode of natural selection where individuals with certain traits are more likely to obtain mates and reproduce
Coevolution	the process where two or more species reciprocally affect each other’s evolution through close ecological interactions
Fossil record	the total collection of all discovered fossils—preserved remains, imprints, or traces of organisms—and their placement within the Earth's rock layers
Embryo	the earliest stage of development in a multicellular organism, beginning after fertilization of an egg cell
Homologous structures	body parts or traits in different species that share a common evolutionary ancestor, even if they now serve different functions.
Extinct	the permanent disappearance of a species, subspecies, or group of organisms, occurring when the last individual dies
Vestigial organs	physical remnants of body parts that had a significant function in an ancestor species but have become functionless, reduced, or repurposed in the modern species
Molecular clock	a technique in evolutionary biology that uses the relatively constant rate of mutation in DNA or protein sequences to estimate the timing of evolutionary events
Relative dating	the science of determining the relative chronological order of past events, fossils, or rock layers without determining their absolute age
Absolute dating	the process of determining a specific, numerical age of fossils, organic remains, or geological layers
