The Darwin theory and the evidence of the descent with modification were published in the ‘The Origin of Species’ in 1859. The lab aligns very well with this performance expectation since students are deciding which characteristics of the embryonic development process of multiple species to use as evidence. prokaryotic and eukaryotic. The practice of finding patterns in the data leads students to see that evolution has caused descent with modification. These genetic differences are heritable and can be passed on to the next generation — which is what really matters in evolution: long term change.
This resource is only available on an unencrypted HTTP website. The concept of "descent with modification" was proposed by _____. Clarification Statement: Emphasis is on explanations of the evolutionary relationships among organisms in terms of similarity or differences of the gross appearance of anatomical structures.

After students collect the data on their chosen embryonic characteristics they need to analyze it by looking for the patterns in the data. In this activity students examine the process of embryo development for eight different animals to answer the question of whether animal embryonic development supports or refutes the theory of descent with modification. This activity provides an opportunity for students to participate in argumentation. They use experiments and research... Five pages take biologists on a generalized survey of the origin of life. It is only part of a reading and students do not construct any explanations on their own for this disciplinary core idea, but it can help them when doing the lab where they construct an explanation for how embryos support or refute the theory of descent with modification. They need to construct a data table that best helps them make sense of their data and then think about the patterns they see and the relationship between structure and function in the embryonic characteristics. They need to construct a data table that best helps them make sense of their data and then think about the patterns they see and the relationship between structure and function in the embryonic characteristics. The NGSS standards addressed in the lesson are also included in the teacher’s notes. Comments about Including the Performance Expectation The link to the scrapbook within the...

The justification aspect, explaining why their evidence is important and how it relates to the claim, is important for students to articulate their thinking. ©;2005 Pearson Education, Inc., publishing as, (Activity: Darwin and the Galápagos Islands), (Activity: The Voyage of the Beagle: Darwin's Trip Around the World), Chapter 22: Descent with Modification: A Darwinian View of Life. Comments about Including the Disciplinary Core Idea Quickly find that inspire student learning. In this activity from ARKive students look for similarities between the basic body plan of different vertebrates as evidence of evolutionary change. Plan an investigation individually and collaboratively, and in the design: identify independent and dependent variables and controls, what tools are needed to do the gathering, how measurements will be recorded, and how many data are needed to support a claim. They examine the structures in a leaf and the roles that they play. The justification aspect, explaining why their evidence is important and how it relates to the claim, is important for students to articulate their thinking. While Charles Darwin is generally called “the father of evolution,” the basic idea for this concept was actually developed by both Darwin and Alfred Russel Wallace. The way the activity is written for students emphasizes the idea of looking for patterns in the data, but explicit discussion by the teacher in this part of the lab will help students to internalize how this crosscutting concept is an essential part of the investigation. endobj

stream To make the activity closer aligned to the Disciplinary Core Idea, teachers may want to give students the pictures of homologous structures such as animal forelimbs and asked them to construct an explanation for whether they support or refute descent with modification. Educators earn digital badges that certify knowledge, skill, and experience. Genetic drift. Construct, use, and/or present an oral and written argument supported by empirical evidence and scientific reasoning to support or refute an explanation or a model for a phenomenon or a solution to a problem.

MS-LS4-2 Apply scientific ideas to construct an explanation for the anatomical similarities and differences among modern organisms and between modern and fossil organisms to infer evolutionary relationships. Students are given the choice of pictures of embryonic development from eight animals from which to choose and develop their argument. Several questions are provided for the students to assess whether their argument is convincing, and students share their work with others in a round-robin format.

Comments about Including the Crosscutting Concept Descent with modification means that children inherit most of their physical traits and body systems from their parents, but that small changes (modifications) might happen in some children due to mistakes or miscopies in the children’s genetic code. [/ICCBased 3 0 R] The example of homologous structures such as vertebrate limbs is used as a part of the introduction to the lab, showing that it can be used as evidence for the theory of descent with modification.
