← homologous – structures of organisms related to one another through common descent (wing of bat, arm of human, flipper of a whale)…
Organisms that are closely related to each other will share some features with all other organisms and share some features only with organisms from this same group.…
2. Traits: The shared species of traits are the instincts to hunt for food (scavenge), and the trait to hunt in packs and stay together. However, the Red Wolf is different compared to the other species that I have chosen, because the Red Wolf has a larger body type compared to the other species that I have chosen.…
Synapomorphies: a shared, derived trait found in two or more taxa that’s present in their most recent common ancestor…
2. According to modern evolutionary theory, vertebrate embryos (i.e. frog, reptile, bird, mammal) have similar characteristics and follow similar patterns of development because:…
Comparative Anatomy: these studies provide strong support for evolution, these help to sort out evolutionary relationships. Homologous structures have a common evolutionary origin but have a different function (hand bones in a human, bat, and dolphins) Analogous structures have a similar function but have different evolutionary origins (bird wings vs. bumblebee…

analogies are comparisons of what is already known and what was observed or found, and…
Sharks and dolphins are examples of convergent evolution. They belong to widely different vertebrate groups—sharks are fish, whereas dolphins are mammals—yet, they live in similar environments and have evolved similar characteristics. Note their similar overall shape and coloration, location and shape of dorsal (back) fins, and shape (but not orientation. ◆ Convergent evolution: are Unrelated species living in similar environments and facing…

Clostridium Difficile: bacterium that can cause symptoms ranging from diarrhea to life-threatening inflammation of the colon. Most commonly affects older adults in hospitals or nursing homes and typically occurs after use of antibiotic medications.…
the stronger the gene/trait, the more likely is will adapt and be reproduced, vice versa…
Describe below what it is you are investigating. Clearly state the hypotheses you are testing. Remember that hypotheses are statements, not questions. (This section should be four or five sentences in length.)…
Evolutionary theory explains the existence of homologous structures adapted to different purposes as the result of descent with modification from a common ancestor. Similarities and differences among homologous structures help determine how recently species shared a common ancestor. For example the front limbs of reptiles and birds are more similar to each other than either is to the front limb of an mammal. This similarity indicates…
