Natural Selection Flashcards
To study for test on Monday
What is the evolutionary process by which animals adapt to their environments over the time of hundreds, thousands or even millions of years, in order to survive?
Natural Selection
What contains all living and non-living things occurring in an organism’s habitat.
The Environment
What is a group of organisms of one species that interbreed and live in the same place at the same time?
Population
What are traits passed down from generation to generation and sometimes undergo changes over time. These changes may be caused by Natural Selection or a mutation of DNA?
Descent with Modifications/Evolution
What is the early developmental stage of an animal while it is in the egg or within the uterus of the mother?
Embryo
What is the genetic change or mutation that helps an organism survive and reproduce in its environment.
Adaptation
What is the evolutionary process in which one population of a species changes over time to the point where the population is distinct and can no longer interbreed with the original population?
Speciation
What is the organisms that can interbreed to produce fertile offspring?
Species
What is the similar physical features in organisms that also shares a common ancestor but serve different functions?
Homologous Structure
What is it called when body parts in different species have similar functions but different structures and evolutionary origins?
Analogous Structure
What organ or anatomical structures that have been retained during evolution but have lost some or all of their ancestral functions
Vestigial Structure
What is the complete disappearance of a species of plant, animal, or other organism from Earth?
Extinction
The Whale Hipbone, Wisdom Teeth, and Appendix are all examples of what structure?
Vestigial Structure
The Human Arm, Bat Wing, Whale Flipper and Cat Leg are all examples of what structure?
Homologous Structure
