Evolution
Cards in this deck (20)
- 1Define SpeciesA group of organisms that are physically similar and can mate with each other to produce offsprings.
- 2What did Darwin notice about the finches on the Galapagos islands?Darwin noticed different kinds of finch has different kinds of beak.
- 3What did Darwin do in his 5-year voyage?Darwin observes animals and plants on the Galapagos islands.
- 4Define AdaptionA behavior of physical characteristic that allows organisms to live successfully in its environment.
- 5Define EvolutionThe gradual change in species over time.
- 6Define OverproductionA kind of organism reproduces too much that the food cycle is unbalanced.
- 7What is natural selection?The process by wich individuals are is better adapted to their environment and are more likely to survive and reproduce.
- 8How does natural selection led to evolution?Natural selection leads to evolutionary change when individuals with certain characteristics have a greater survival or reproductive rate than other individuals in a population and pass on these inheritable genetic characteristics to their offspring.
- 9What are homologous structures?Homologous structures are body structures that are similar to related species.
- 10what is an example of a homologous structure?The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale.
- 11What are 4 pieces of evidence that support the theory of evolution?1. The fossil record
2. Genetic commonalities
3. Common traits in embryos
4. The universal genetic code - 12What is geographic isolation?A population of animals, plants, or other organisms that are separated from exchanging genetic material with other organisms of the same species.
- 13How can a geographic isolation lead to the creation of a new species?The organism has to adapt to their new environment and evolve.
- 14What is a branching tree (in relation to the classification of organisms?A diagram shows how scientists think different groups of organisms are related.
- 15What is taxonomy?The scientific study of how living things are classified.
- 16Why do scientists organize living things into groups?Scientists organize living things by observing their observable traits.
- 17What are two parts of an organism's scientific name?Class, Species
- 18What is an example of multicellular heterotroph?Fungi
- 19What domain contains only prokaryotes?Bacteria and Archaea
- 20The moth gizmo showed what animal adaption? Describe this adaption.The gizmo showed moth adaption, before 1900, the air was clean, but now, the air is polluted, so the moths changed the color into black.
