Basics of Evolution
Biology
| Term | Definition |
|---|---|
| What is evolution? | Biological evolution refers to the cumulative changes that occur in a population over time. |
| Evolution (organisms) | Over time individuals change by inheriting new traits. (They adapt to their environment) |
| Science Theory on Revolution | Scientist prediction on how evolution occurred. |
| Are the species related | Yes all of them are related under a tree, not all of the species adapt |
| What is evolution? | Biological evolution refers to the cumulative changes that occur in a population over time. |
| Evolution (organisms) | Over time individuals change by inheriting new traits. (They adapt to their environment) |
| Science Theory on Revolution | Scientist prediction on how evolution occurred. |
| Are the species related | Yes all of them are related under a tree, not all of the species adapt |
| Fossil (14.2) What is a fossil record? Bas auras Fossil | Fossils are remains left by organisms that lived millions of years ago. The basilosauras suggest that the organism is extinct because nothing is left of it |
| Geographic distribution | Patterns of how organisms evolved, explaining how features come onto an animal from evolving. |
| Homologous Structures | Similar structures from organism to organism like how fins are similar to hands on humans |
| Vestigial structures | remnant of a structure that may have had an important function in a species' ancestors, but has no clear function in the modern species |
| Similarities in structure, DNA sequence | Many organisms have the same kind of structure but its all in a different sort of shape, like the embryos are the same, body parts are similar in a way. |
| (15.3) How do fossils forum? | Soft parts of organisms decay but hard parts of the body like bones stay |
| Geologic Time Scale | Earth's history organized into four eras: Precambrian, Paleozoic, Mesozoic, and Cenozoic |
| Relative Dating of fossils Radiometric of Fossils | determination of absolute ages of rocks and fossils through calculations based on a radioactive isotope's fixed rate of decay |
| Continental Drift | motion of continents about Earth's surface on plates of crust floating on the hot mantle |
| Georges Buffon Ideas | Fossils and animals were similar |
| Adaption | Body parts of animals adapt according the environment they live in |
| Jean Baptiste Lamarack ideas | Life evolves and changes, revolution is a process of adaption. Body parts of organism evolves. |
| Darwins Observations | Evolution occurs overtime. He use to believe that animals didn't |
| Charles Lyell Ideas | Says that an erosion caused for the earths shape from many earthquakes occurring over the years.It is how organisms had to adapt to new environments |
| Thomas Malthus | Says the change in organisms or evolution was caused by disease, famine, and homelessness. Some population in organisms grow much faster than others. |
| Natural Selection | Based on the environments the organisms change process by which individuals with inherited characteristics well-suited to the environment leave more offspring than do other individual |
| Population numbers and variations | Population of organism may increase because some organisms adapt or don't adapt to their new isolated population. |
| Artificial Selection | selective breeding of domesticated plants and animals to produce offspring with desired genetic traits |
| How do pesticides show natural selection | Pesticides begin to get use to the sprayings that kill them. So the population on pesticides will no longer affect them. |
| (14.5( how does natural selection cause the sickle cell allele to stay in some pop. | It causes the sickle cell alleles to stay in the same populations by having the organisms have physical reactions to their environment. |
| how does anti bio tic resistance evolve in bacteria. | Because the anti bio tic protects the bacteria so that the bacteria can evolve and adapt. |
| Gene Pool (14.4) | all alleles in an individuals that make up the population |
| What process lead to variation | which organisms survive through the environment, and the ones that adapt to it |
| Frequency of Alleles | Having more common alleles in a gene pool so there is more chance of something in an organism occurring in the next generation. |
| Micro evolution | evolution at it's smallest scale, a generation to generation change occurring slowly. |
| Hardy-Weinberg Equilibrium | condition that occurs when the frequency of alleles in a particular gene pool remain constant over time |
| Genetic Drift | change in gene pool due to chance of being alone |
| Bottle Neck effect | disaster reduces the size of the population and its gene pool |
| Founder Effect | few individuals colonize or they are in a new habitat |
| Gene Flow | exchange of genes between populations |
| Mutation | Something going wrong in the alleles that change the outcome of the organism |
| How does natural selection lead to fitness | Organisms must adapt to their environment so become better/stronger for next generation |
| Peter and Rosemary Grants study | That all same species of organisms are different because they must adapt to the environment. |
