Chapter 13, Problem 8WIO
Summary Introduction
To determine:
The cause that the embryos of many species look similar, but appear different as adults and to study the development that insights into evolutionary relationships.
Concept Introduction:
The egg cell and sperm cell fuses together to form a zygote that divides and form embryo. The embryo develops and forms into an organism that resembles its parents. The embryonic stages of some species resemble each other, but they differ in their adult stages.

- First, concerningthe evolution of development, what have been the changes in developmentalmechanisms that give rise to different phenotypes? A second question, closelyrelated to the first, is how do genetic differences among species map onto phenotypic differences? Third, what is the role of development in either constraining or enhancing evolutionary change in characters? That is, how does development affect “evolvability”? Fourth, how does developmental information help usidentify homologous characters, or even define homology? Finally, can understanding development help us understand the origin of novel characteristics?arrow_forwardCan convergent (or parallel) evolution of similar morphology in two different lineages involve DNA sequence evolution in different parts of the same developmental gene?arrow_forwardMost of what we know about animal development comes from studies in model organisms like C. elegans and D. melanogaster. Why are these studies useful for learning about human development? O a) The genes involved in development are evolutionarily conserved O b) Genes that are active in development of other animals are not likely to be active in human development Oc) Studies in model organisms are not useful for understanding human development O d) All animal development is the exactly same, including human developmentarrow_forward
