Design Your Own Species 10/29/17

Summary : My group and I were posed with the task of deigning a species that could not only survive, but thrive in Planet C. Planet C is a tropical environment with a flat terrain. It is predominantly rain forests that are moist and hot. There are many large pools of water or lakes in the rain forests where killer poisonous plants grow. The vegetation is comprised of an abundance of leaves, nuts, and fruits and some of the animals are carnivorous snakes, monkeys, fish, insects and birds. Our animal lives in the multitude of lakes in the rain forests and eats both plants and animals. It is in the middle of the food chain, eating fish, algae and seaweed and getting eaten by birds and carnivorous snakes. The fact that it is an omnivore allows the animal to survive longer. For example, if the fish dies off this animal can eat seaweed. The animal will still eventually die because the seaweed population will decrease, but the since it is an omnivore it will live longer.

Cladograms, cladograms, cladograms 10/22/17

Image: Pierre Kleinhouse Summary:  When we think of evolution we see monkeys magically turning into humans, but what is missing from that picture is the portion below it that makes it a cladogram. What is a cladogram? A cladogram is a diagram that shows the common characteristics of certain animals, as well as how closely related they may be. The top of the cladogram includes the organisms name and sometimes a picture. On the side of the cladogram, you will usually see different characteristics. Since a cladogram is drawn at a downward angle, the characteristic applies to everything above that point on the diagram. As you go up the cladogram, the animal at the top has all the characteristics listed throughout the cladogram. Along with this, the points in which two animals meet is not when they evolved from one another, but their common ancestor. Lastly, the diagonal line of a cladogram represents time. S&EP-Models: SliderBase Cladograms are a diagram or model that s

4 Lines Of Evidence 10/15/17

Embryology is studying how creatures develop before being born and noting comparisons. Next, there is the fossil record in which you compare and contrast animals that are living today with fossils of animals who lived in the past to bridge the gap and help figure out which animals resemble each other more. Lastly, you can use DNA to see which animals are closely related to one another. Diving a bit deeper into the fossil records, we can see how different organisms of the past acted and see how that applies to

Darwin's Finches 10/8/17

Image: Nat Geo Education Blog - National Geographic Summary:  What is natural selection? Do the strong survive and the weak die? Not necessarily. Natural Selection is when organisms who are better adapted to their environment outlive those who aren't and have a chance to pass down their genes, which is the ultimate goal for all living creatures. Out of the five fingers of evolution, natural selection is the only "finger" that can cause adaptations. You've probably heard that organisms, most commonly dogs, are bred. Humans pick and choose which dogs can mate and with whom to determine the outcome. This case is true for natural selection, except for the fact that there is no dog breeder causing evolution. Evolution acts on nature. The idea of natural selection was first proposed by Charles Darwin, who stated that nature could determine which organisms survive and which don't. He traveled on the HMS Beagle that departed for the Galapagos Islands on 12/27/183
