Exercise 3 through a series of breeding experiments

This preview shows page 4 - 7 out of 8 pages.

Exercise 3: Through a series of breeding experiments on the heritability of traits, you conclude that the markings on the backs of the Caminalcules have no correlation with the markings of their parents or ancestors. In other words, you find that the markings are not heritable 5. Is a trait that is not heritable, like the markings on the backs of the Caminalcules, useful in creating a taxonomy? What do shared, inherited traits tell us about the relationships among taxa? ( 1 pt ) .
6. On a piece of notebook or scrap paper, revise your taxonomy to reflect the new information you’ve learned about the markings. Once you’ve settled on a revised taxonomy, illustrate it here: ( 1 pt ) 4

Taxonomy was (and continues to be) a major topic of scientific debate. What insights did this exercise give you into issues that may arise? Why do you think some distantly related organisms have shared features not found in their common ancestor (for example, birds and bats both have wings even though their common ancestor does not)?

Exercise 4 : Phylogenies are best expressed in the form of a tree in which each branch represents inferred evolutionary relationships among various biological species. To ascertain the evolutionary relationships, traits are scored for wither presence or absence and placed in a matrix. Bilateral Symmetry Backbone Jaw bone Four limbs Hair Jellyfish Present Absent Absent Absent Absent Lamprey Present Present Absent Absent Absent 5
Sunfish Present Present Present Absent Absent Newt Present Present Present Present Absent Dog Present Present Present Present Present Once you have created your matrix, you can create a phylogenetic tree. To create a phylogenetic tree, you group the organisms such that the organisms on the left share more traits in common than those on
