N.S. by Evolution
| Question | Answer |
|---|---|
| Similar structures in different species, example: similar bones in a hand, fin, or wing. | Homologous Structures |
| He proposed the Theory of Evolution by Natural Selection. | Charles Darwin |
| The process of species changing over time. | Evolution |
| Combining genetic material from two parents to create a genetically different offspring. | Sexual Reproduction |
| A group of organisms that can mate and produce fertile offspring. | Species |
| One form of evidence for evolution, at the embryonic stage of life different species look very similar. | Embryonic Development |
| A diagram that shows the evolutionary relationships between organisms. | Phylogenetic Tree |
| A difference in shape, form, or function. | Variation |
| A trait that gives an organism an advantage, a useful trait. | Adaptation |
| A level of classification that is very broad and contains six groups. | Kingdom |
| Best explanation based on data/observations. | Theory |
| A species that two other species evolved from. | Common Ancestor |
| A change in the DNA sequence that leads to variation. | Mutation |
| Things in the environment needed for survival, examples: food, water, shelter. | Resources |
| Preserved remains or evidence of an ancient organism. | Fossil |
| When organisms fight over resources due to overpopulation. | Competition |
| Occurs when too many organisms are produced in a given area, leads to competition. | Overpopulation |
| A tool used by scientists to identify organisms. | Dichotomous Key |
| The organisms that are better suited to their environment survive and reproduce. | Natural Selection |
| An innate behavior of a newborn mammal that gradually accustoms the young from milk to an adult diet. | Suckling |
| Response to a stimulus by automatically moving directly toward or away from | Taxis/Taxes |
| periodic movement and return of animals from one place to another | Migration |
| Slowing of metabolic activities during hot, dry seasons | Estivation |
| Slowing of metabolic activity during winter when food supplies are low | Hibernation |
| Learning process by which an animal decreases or stops its response to a repetitive stimulus that neither rewards nor harms it. | Habituation |
| A process in which a young animal follows the characteristics of his/her mother after birth. | Imprinting |
| Learning process in which an animal makes a mental connection between a stimulus and some kind of reward or punishment. | Classical Conditioning |
| Behavior that appears in fully functional form the first time they are performed | Innate Behavior |
| A behavior that develops over time, also known as an acquired behavior | Learned Behavior |
