Patrick Cardozo Dr Jeffrey Martz Geo 1306 3/24/2017 Second research paper analysis; Evolutionary trends in Triceratops from the Hell Creek Formation, Montana The authors were interested in knowing the actual evolutionary trends in the triceratops from the Hell Creek Formation, Montana; Some previous Palaeontologists have recognised two Triceratops species, Triceratops horridus and Triceratops prorsus, due to the fact that the length and shape of the horns and the size and structure of the…

however, while these finches may have shared similarities they also had many differences. The main difference Darwin noticed was the finch’s beaks they were all different shapes and sizes. He later discovered that the beaks had changed to where they lived to help them get food and adapt to the environment on that island. The medium ground finch has a small beak that allows them to crack the smaller nuts due to the larger finches stealing all the bigger nuts. (Frater,…

possessing a stronger or larger beak. This allows this individual to eat more, therefore increasing its rate of survival and enabling it to produce more offspring. The surviving birds that possess this trait will pass it on to their offspring and the birds without strong beaks will eventually die out. Beak morphology- Darwin’s finches (above) are an example of how a variation in beak reflects the food being consumed. The finch on the far left (Geospiza magnirostris) has a large beak in…

Introduction The most recognizable characteristic in the Buceros rhinoceros is the casque above the bill. Buceros rhinoceros species are part of the family Bucerotidae which are omnivorous birds that defend a fixed territory (Kitamura, 2011). In this species we can identify sexual dimorphism. As it can be noticed by pure observation, there is a few differences between sexes. The most significant detectable variations are body and casque length. Adult males show both larger bodies and casques…

One reason that many believed that the giant squid was a passive hunter was the amount of ammonium in its tissues. There are two groups of squid in relation to density in water; the first are denser than water and must swim to stay afloat, the second are “nearly neutrally buoyant” (Clarke et al. 1979). The giant squid falls into the second category; it remains buoyant because of ammonium chloride filled pockets in its muscles, which balance its density. This means that it does not need to be…

The hyacinth macaw lives in the Amazon RainForest, has bright gorgeous blue feathers, and eats lots of berries, nuts, and tiny bugs. The hyacinth macaw is mostly found in tall trees , swamps, forests, and near rivers in the Amazon RainForest. Also,the hyacinth macaw is found mostly in riverside tropical rainforest and palm swamps. It’s habitat goes throughout the hyacinth macaw’s range, however, from the moist forest with a broken canopy, to mature palm forest, to grassland .More information,…

website, flamingos are pink because they eat a certain type of shrimp called brine shrimp. The brine fish live in salt water lakes in both hemispheres which is usually where the flamingo lives. The flamingos grab the shrimp with their uniquely shaped beaks and then turn upside down to strain out any mud and water. After the water and mud is strained, they enjoy their meal. There is a nutritious natural chemical in the shrimp called Beta Carotene that gives the birds its bright color. Beta…

Turkeys are beaten abused and mistreated by animal slaughters. Their beaks are broken off with no pain killers. They are stepped on and they are killed with no pain killers. (huffington post) Every year millions of turkey are killed for thanksgiving alone. I am going to give you two strong reasons why you shouldn't eat turkeys anymore for thanksgiving. One Turkey are treated horribly, two turkey are not sterile. One, according to P.E.T.A turkeys are handled improperly and are abused. When they…

In the article of natural selection by Charles Darwin there is a lot of strong points and powerful statements, but do we ever think about what makes them strong and powerful statements. You ever wonder what a theory really is? Darwin statement is considered a theory. It only became a theory through the use of ethos, pathos, and logos. No matter what articles always use some sort logos, ethos, and pathos. This is how we make theories and get reactions like we do because we use logic which is…

they also hover by flapping their wings in a figure eight pattern. The Hummingbirds feet are not used for hopping or walking, but perching. Hummingbirds are basically like bees, going around and sucking the nectar from flowers with their long, skinny beaks. They mainly eat flower nectar, tree sap, insects and pollen. Also, their long tongues help them lick their food at a rate of thirteen licks per second. Hummingbirds weigh 0.08 to 0 .7 ounces and they are 1.75 to 1.8 inches in length. Female…
