Lab 10: Kingdom Animalia Introduction Animals all share some characteristics:
1) Multicellular
2) Heterotrophic
3) Their cells have no cell wall
4) At some time in their life they are motile.
There are many phyla within the animal Kingdom, and in this activity, you will explore these phyla by building a dichotomous key that will allow you to consider almost any animal and determine which phylum it belongs to.
Part 1: Organizing information for the dichotomous key 1) List the 9 animal phyla of macroscopic (visible) animals: Porifera, Cnidaria, Platyhelminthes, Nemotoda, Annelida, Arthropoda, Mollusca, Echinodermata, and Chordata. 2) Use on-line or library resources of your choice, to gather information about these 9 phyla.
a. Start by finding two example species per phylum to help tie into your previous knowledge about animal types. Write down these examples.
b. Make a list of characteristics that you could use that would help you tell these 9 phyla apart. The final goal is to build a…
A group of organisms that includes a recent common ancestor and all its descendants is (a) polyphyletic (b) paraphyletic (c) monophyletic (d) an example of horizontal gene transfer (e) a sister group
3- Which of the following processes contributed the most to the successful evolution of the millions of animal species?
A) meiosis and sexual reproduction
B) the arrangement of cells into tissues
C) development of multicellularity
D) the formation of an embryo and establishment of a basic body plan

What data would you collect to reconstruct their phylogenetic history?arrow_forwardTest Your Understanding Apply and Analyze 9. In interpreting a cladogram, (a) we can identify the specific ancestor of each taxon by tracing each branch back to the node closest to the root (b) taxa on the right side of a cladogram have evolved from the taxa on the left side (c) the relative placement of smaller branches allows us to determine the number of years since a particular taxon has evolved (d) we can determine relationships by tracing along the branches back to the most recent common ancestor (e) we must first identify horizontal gene transferarrow_forward12) Instead of 1 uniform definition, biologist use over 20 different definitions of "species". Why? A) Because scientists searching for life on other planets do not want to be restricted to the narrow definition that applies to earth based life forms B) Because historically biologist have argued over the correct definition of this term and therefore have split into seperate "camps" for different definitions C) Because life includes both sexual and asexually reproducing organisms D) Because life is so diverse that no single definition used so far can be uniformly applied in a meaningful way to all organismsarrow_forward

Microevolution describes the evolution of small organisms, such as insects, while macroevolution describes the evolution of large organisms, like people and elephants Microevolution describes the evolution of microscopic entities, such as molecules and proteins, while macroevolution describes the evolution of whole organisms Microevolution describes the evolution of organisms in populations, while macroevolution describes the evolution of species over long periods of time Microevolution describes the evolution of organisms over their lifetimes, while macroevolution describes the evolution of organisms over multiple generations.arrow_forward
