Comparative embryology

comparative embryology Comparative embryology the first known study of comparative developmental anatomy was undertaken by aristotle in the fourth century bce  he noted the different ways that animals are born: from eggs ( oviparity , as in birds, frogs, and most invertebrates), by live birth ( viviparity , as in eutherian mammals), or by producing an egg that hatches inside the body ( ovoviviparity , as in certain reptiles and sharks.

Evolutionary embryology charles darwin's theory of evolution restructured comparative embryology and gave it a new focus after reading johannes müller's summary of von baer's laws in 1842, darwin saw that embryonic resemblances would be a very strong argument in favor of the genetic connectedness of different animal groups. All human and animal embryos go through very similar stages of early development see also humans and animal embryology what are the key things in development that we share this page introduces a few of the concepts of comparative development shared with all animals.

Teacher note this is currently only a draft designed to help k12 students understand comparative embryology i am currently looking to simplify concepts and include images on this page.

Comparative embryology supports the theory of evolution because scientists have found that the embryos of many different species show similarities, which implies they share a common origin for example, in humans the embryo passes through a stage in which it has a gill structure similar to that of fish. Answer embryology does not provide any evidence for evolution ernst haeckel's comparative embryo drawings have been known to be fraudulent for over 60 years although they are still used in some textbooks and by some ardent evolutionists embryos are different all through their development.

Embryology is the study of the development of embryos from fertilization until they become fetuses, or the point at which you can distinguish the species comparative embryology is the comparison of embryo development across species. Comparative embryology: the vertebrate body all vertebrate embryos follow a common developmental path due to their common ancestry all have a set of very similar genes (the homeobox genes ) that define their basic body plan. Comparative embryology is the scientific study of the similarities in structure between the embryos of various species that suggest a possible link to a common ancestor early developmental patterns are collated and compared to investigate the likely relationships among evolved organisms.

Comparative embryology is the branch of embryology that compares and contrasts embryos of different species, showing how all animals are related. Comparative embryology: the vertebrate body even before darwin proposed the theory of evolution through natural selection, ernst von baer claimed that the more closely related any two species are, the more similar their development.

Modern comparative embryology during the modern age, scientists have used comparative embryology to study and gather evidence of evolution, which can be traced back to the work of karl ernst von baer and oscar hertwig in the 1800s.

Comparative embryology is the study of how different types of organisms compare to each other during their fetal stages scientists have used comparative embryology to study and gather evidence of evolution. Examining seminal and current experiments in such fields as comparative embryology (repurposing of conserved primitive structures) and developmental genetics (function, conservation, and evolution of the hox genes), shubin leads the reader to understand that the evolution of man is supported by a cacophony of different scientific voices.
