Structures derived . from a common . ancestor or . same . evolutionary or . developmental . origin. May not perform . the same function but they share a common ancestral origin. . Phylogeny. The evolutionary history of a species or group of species. . Convergent Evolution. A process in which species from different evolutionary branches may come to resemble each other if they live in similar environments and natural selection favored similar adaptions.. Which animal has INCREASED fitness?. Living in a dry, wooded area in the fall season…... Living in north Canada…in the winter time….. What are these called??. What is it called when humans intervene and create changes in a population?. Phylogenetic Trees. A. . Show how closely related various species are. . B. Some species look different, but are actually very similar. Comparative Anatomy. . A. Homologous Structures – Inherited from a common ancestor, but adapted to a different function (ex. human hand, bat wing, whale fin). Bat wing. Mole foot. Analogous structures. are . not. evidence of a common ancestor.. Analogous structures. have different structures but a similar function.. Analogous structures. Analogous structures=evidence of convergent evolution. Struggle for existence. High birth rates and shortage of life’s needs. Food and living space. Fitness – ability to survive and reproduce in your environment. Survival of the fittest. Adaptation. Characteristic to . Comparative Morphology. Analogous Structures. Structures with similar . function. but different internal structure, development (bird wing and insect wings, dolphin fin and shark fin). Does . NOT . show evolutionary relationships. Lecture 65 – Lecture 66. Evidence of Evolution. Ozgur. . Unal. 1. Support for Evolution. 2. The. theory of evolution states that all organisms on Earth have descended from a common ancestor.. The theory explains the existing data and suggests further areas for experimentation.. Derived traits. are newly evolved features, such as feathers, that do not appear in the fossils of common ancestors. .. Ancestral traits. are more primitive features, such as teeth and tails, that do appear in ancestral forms.. A hypothetical trace of evolution. One original common ancestor. Scientists use both morphology and genetics to produce phylogenic trees. Morphology- share similar physical characteristics. Analysis of genetic similarity. th. , 2018. Pre-Class:. How would you define a species?. In This Lesson:. Speciation. (Lesson 3 of 3). Today’s Agenda. The Origin of Species. Well, not Darwin’s work. Just his work.. Where is this in my book?. Causes of Evolution: . Natural Selection . Migration. Mutation. What is Natural Selection? . Survival of the ‘fittest’. Occurs through INHERITED adaptations. What is migration?. Movement of animals from one area to another. . Homologous structures. Human Arm . Bat Wing . Whale Flipper. . Analogous. Structures . Similar functions but NOT structurally related. . Insects are arthropods and birds are vertebrates. . The wing of a bird and the wing of a butterfly are examples of .
