1 page: Describe the radiation in vertebrate forms from phylotypic stage by focusing on three groups of vertebrates and then tracing the development of several homologous features in each group. Connect specific embryological structures in the phylotypic stage to divergent morphological structures in the adults of each of these groups.
Answer the following:
More recently evolved organisms have modified the stages of embryological development. Would you expect early or late stages to be modified the most? Why?
The basic stages of embryological development are remarkably similar for a wide range of organisms. How would you explain such consistency?
As cells invaginate and move about, do they “know” where they are? If not, how is movement controlled? If so, how do they perceive their position.
Is parental care of a species a factor that affects embryological development? If so, how?

- EVOLUTION LINK What is the common ground between evolutionary biologists and developmental biologists who have adopted the perspective known as Evo Devo?arrow_forwardDescribe the Anatomical Changes from Early to Late Stages Species Embryo (A-F) Human | Chicken Rabbit Tortoise Salamander Fisharrow_forwardDarwin’s finches (Thraupidae, Passeriformes) have beaks of different shapes that allow them to feed on many different diets: insects, seeds, berries, and young leaves. For example, large ground finch has a very deep and broad bill adapted to crack hard and large seeds, while the cactus finch has an elongated and pointy beak for probing cactus flowers and fruits. Geospiza finch bills develop their distinct shapes during embryogenesis and are apparent upon hatching. Figure below is species-tree estimation of phylogenetic relationships among the Galápagos finches using mtDNA and nuclear loci information. ***Branch lengths are proportional to time and genetic distance except for abbreviated basal node depth.*** Photographs of profiles of each species are shown. Identify all species pair(s) who have the most similar DNA sequence and clearly explain why.

- Many species look similar as embryos. What causes them to appear different as adults? Why does the study of development give insights into evolutionary relationships?arrow_forwardDescribe how changes in the ladybugs'environment may influence their survival and/or reproduction. Make sure to use the vocabulary terms adaptation, natural selection, and polymorphic.arrow_forwardDevelopment of an animal is controlled by the genes that are expressed during development. What roles have been proposed for Hox genes in the evolution and morphology of animal species? Group of answer choices 1. Variation in the Hox genes may have spawned the formation of many new body plans. 2. All of these descriptions are correct. 3. The number and arrangement of Hox genes varies among different types of animals. 4. Increases in the number of Hox genes may have led to greater complexity in body structure.arrow_forward
