# Picture Vocabulary Slides ## Evidence for Evolution ### **Picture Vocabulary** **Name:** **Date:** © Accelerate Learning Inc. - All Rights Reserved ## Evolution **Equus** Recent **Pliohippus** Late Miocene **Merychippus** Middle Miocene **Mesohippus** Late Eocene An image of a series of evolutionary ancestors of the horse. It shows skeletons of *Equus, Pliohippus, Merychippus*, and *Mesohippus* over the time periods that they existed. The image also shows some of the skeletal changes through time including the skull, the legs, and the feet. **Descent with modification from a preexisting species** © Accelerate Learning Inc. - All Rights Reserved ## Biogeography An image shows the geographical location of where certain flightless birds can be found. *Rhea* in South America, the *Ostrich* in Africa, the *Emu* and the *Cassowary* in Australia, and the *Kiwi* in New Zealand. **The study of the past and present geographical distribution of species** © Accelerate Learning Inc. - All Rights Reserved ## Homologous Structure - Whale - Frog - Horse - Lion - Human - Bird An image contains a series of pictures showing the bones of the front limbs of a whale, frog, horse, lion, human, and bird. The image is clearly demonstrating the homology of these bones. **An organ or bone that appears in different animals, underlying anatomical commonalities demonstrating descent from a common ancestor** © Accelerate Learning Inc. - All Rights Reserved ## Analogous Structure An image of a butterfly and an eagle flying. **Various structures in different species that have the same appearance, structure, or function but have evolved separately and do not share a common ancestor** © Accelerate Learning Inc. - All Rights Reserved ## Comparative Embryology - Shark - Lizard - Chicken - Pig - Human A series of images show the embryonic development of a shark, lizard, chicken, pig, and human. You can clearly see the similarities within the early stages of development. **The study of the similarities and differences in the stages of embryonic development among different species** © Accelerate Learning Inc. - All Rights Reserved ## Fossils An image of fossilized dinosaur bones. **Preserved parts or traces of animals and plants that lived in the past** © Accelerate Learning Inc. - All Rights Reserved ## Fossil Record An image of a series of layers of rock with different fossilized organisms in them. Layer 1 contains a skull, a bone, a leaf, and a snail. Layer 2 contains a fern, a bone, a fish, and a trilobite. Layer 3 contains a shrimp, a fish, a bivalve, and a sponge. Layer 4 contains a clam, a trilobite, and a worm. **The fossils and their locations in the sedimentary layers of Earth's crust, which provide information about things that lived in the distant past** © Accelerate Learning Inc. - All Rights Reserved ## Natural Selection An image of a fox running and hunting mice in a field. There are two rows of mice. The first row shows many white mice and a few dark mice. The second row shows fewer white mice and many more dark mice. **Natural Selection** Some mice are eaten by the fox. The surviving mice reproduce. The white mice population is greater than the dark mice population. The white mice are more visible to the fox; thus, the white mice are eaten more. The next generation contains a higher number of dark mice. **Differential survival and reproductive success among a group of organisms due to differences in the inherited traits or characteristics of the organisms** © Accelerate Learning Inc. - All Rights Reserved ## Gradualism An image of a branch of a tree with a series of butterflies on it. All the butterflies are different shades of red from dark red to light orange. **The theory that species evolve slowly and gradually over extended periods of time** © Accelerate Learning Inc. - All Rights Reserved ## Punctuated Equilibrium An image of a series of butterflies. They start off as orange and then switch to black in a number of relatively quick changes. **Changes in Phenotype** **A mode of evolution characterized by relatively short bursts of rapid evolutionary change interspersed with long periods of little change** © Accelerate Learning Inc. - All Rights Reserved ## Stasis An image of a horseshoe crab. **A long period of time in which little or no change occurs within a species** © Accelerate Learning Inc. - All Rights Reserved ## Rock Strata An image of a cliff face with many layers of red, white, and gray rock. **Beds or layers of sedimentary rock having approximately the same composition throughout** © Accelerate Learning Inc. - All Rights Reserved
