- Darwin’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.

- According to Richard Owen, the forelimbs of an adult human (with hands, adapted for grasping fruit from a tree), and the forelimbs of an adult bat (with wings, adapted for flight), are both derived from the same mammalian embryological structures, so they must represent: homologous structures, with similar embryonic anatomy, but different functions analogous structures, with different functions, and different embryonic anatomy analogous structures, with similar functions, but different embryonic anatomy analogous structures, with different embryonic anatomy, and different functions homologous structures, with different embryonic anatomy, but similar functionsarrow_forwardDescribe 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.

This refers to the fact? a) all the ectoderm cells remain the same b) the cells derived from the endoderm to form osteocytes that secrete collagen c) the cells of the endoderm form chondrocytes that become notochord d) genes are activated or surpressed in the cells from the original mesoderm causing them to become chondrocytes and osteocytes the stem cells that sequentially produce the componets of the skeleton e) genes are not involved in this function?arrow_forward

Insect and bird wings are similar in function but not in structure. Paleontologists have used fossils to trace the evolution of the modern camel. Many organisms have structures with no apparent function found during embryo development. The presence of gill slits and tails in early vertebrate embryos shows that they may share a common ancestor.arrow_forwardExplain the process how does a mammalian embryo determine which end is its head and which is its tail?arrow_forward
