Evolution and Ancestral Genetics Flashcards
(18 cards)
The process within a population changes over generations that sometimes result in a new species.
Evolution
A characteristic that improves an individual’s ability to survive and reproduce in a particular environment.
Adaptation
A group of organisms that are closely related and can mate to reproduce fertile offspring.
Species
The remains or physical evidence of an organism preserved by geological processes.
Fossil
The geological order in which fossils are sorted by their depth.
Fossil Record
A genetic characteristic that is passed on to offspring.
Trait
The practice of purposefully choosing parents of certain genetic traits to create offspring that possess them.
Selective Breeding
The process in which habitat, climate, and food resources determine adaptation in survival of the fittest to have those who are fit have children who possess those survival traits.
Natural Selection
The average time between two generations in the lineages of a population
Generation Time
Certain qualities that meet the needs of an organism.
Specification
The determination of how past events occur by chronological estimates.
Relative Dating
The accurate process of determining something’s age.
Absolute Dating
A way to represent earth’s history by determining geological events.
Geologic Time Scale
A term used to imply that an organism and its species no longer exists.
Extinct
A theory in which the Earth’s crust is composed of geological formations called Tectonic Plates that float on the mantle and move very slowly.
Plate Tectonics
A group of omnivorous mammals that possess an intelligence not seen in other species. Ex. Humans, Apes, Monkeys, Lemurs.
Primate
A primate group such as humans and their fossil ancestors and a few Apes.
Hominid
A species of bipedal primates in which Humans and their fossil ancestors belong. They are characterized by a large forehead and cranium, a lighter skeletal build, and small teeth.
Homo Sapiens
