Bird Beaks Lab Report

578 Words3 Pages

In Biology class we conducted a lab called “Bird Beaks”, in the lab we were separated into four groups of different bird beaks. Our goal was to see which type of beak was more successful, and if evolution occurred. I claim that Evolution did occur in the bird beak lab because spoons were able to survive and grow throughout everything that occurred and tweezys were able to grow and thrive after migration and everything that followed.

My first piece of evidence and reasoning, is that spoons survived throughout the whole experiment after two natural selections, a migration of tweezys, a natural disaster, and a mutation. We started with seven spoons and ended with thirteen spoons. After the migration the spoons continued to thrive ending with eight spoons even though there was another type of bird eating the food. Then after the natural disaster hit a section of the land, spoons still had five left and reproducing. After another natural selection and one mutation spoons ended with thirteen. …show more content…

At the beginning of the experiment they weren’t there yet. When they did migrate in, seven came along and began to eat the food around them. The next round after that everyone including the tweezys in a certain section were hit by a disaster. Afterwards, they once again grew in population ending that round with four tweezys which was significantly better than the spatula and scupula who had one and three. Evolution was helping the tweezys out here, at any given moment evolution could have chose to kill them off and focus on a different species. Instead evolution had this bird develop a successful beak compared to other birds beaks. After the disaster the tweezys thrived then another round of natural selection and still came in seconds after the spoon mutated. Overall evolution made tweezys’ beaks different than others to see if they survived, and when they did, evolution would keep the beak type cycling around the

In the dirt habitat, the population of fork and knifes began to decrease while the population of spoons began to increase. For instance, in generation 2, forks accounted for 33% of the population, knives had become extinct and spoons accounted for 67% of the population. Additionally in generation 3, the total population was made up of spoons, both knives and forks had become extinct (Table 1A). As for predators in the dirt habitat, the population of pinto bean decreased during the second generation, while the populations of black beans, green beans and white beans slightly increased.

Introduction The bean beetle also known as the Callosobruchus maculatus, is an agricultural pest insect from Africa and Asia. That can be found throughout the tropical and subtropical regions. The lifecycle of a bean beetles is quite short an adult been beetle lays their eggs on the external surface of a bean. The larva hatches from the egg burrows from the egg through the seed coat and into the bean endosperm without moving outside the protection of the egg.

This feeding mechanism can be explained partially by the bird’s beak shape and size. The Chickadee has a short conical beak allowing it to peck into shell and feed on the inside. Yet it is also conical and comes to a point allowing it to grab insects. Thus the Chickadee tends to forage in locations with ample berries, seeds or insects. This diet partially explains why the Chickadee prefers White Oak (Hemert et al, 2012).

Paragraph 1: Introduction - explain your lab. The lab that I chose to do was the “McGraw Hill Higher Education: Natural Selection - Virtual Lab.” I chose this lab because it was the one that most interested me, as I liked the format of the virtual lab. In this lab, I was able to manipulate both the environment and the allele frequency in order to record and investigate the generational breeding patterns of a group of organisms.

This shows that the survival rates of the gall is not just dependent on the size but also on the distribution of the galls in different habitats. This can demonstrate a reason to why the means may have been closely related.

As technology improves, so do human capabilities of altering nature, which in turn creates increased responsibility. This directly relates to genetic engineering, which is beginning to morph into a reality. There are advocates for both sides that convey their personal opinions about the hypothetical results, but neither is clearly superior since both arguments speculate upon an unknown future. Hungarian psychologist, Mihaly Csikszentmihalyi, outlines this topic in his essay “The Future of Happiness,” which focuses on the history of selective breeding and compares the goal of happiness with genetic engineering. Csikszentmihalyi alternates between viewpoints regarding genetic engineering but presents a perspective dominated by warning.

They both conclude that someone was rough with the empty birdcage. Immediately afterward, Mrs. Hale comments on the men’s progress to find evidence, saying, “’I wish if they’re going to find any evidence they’d be about it’” (Glaspell 1416). Mrs. Hale’s remark is ironic because her current conversation about the birdcage’s door hinge is indirect evidence, yet she is growing impatient with the men’s attempts to discover any solid evidence. A little later on, Mrs. Hale relates the idea of a bird to Mrs. Wright by saying, “’she was kind of like a bird herself.’”

In directional selection, one extreme trait is favored over the mean trait or other extreme trait; and this occurs in environments that have undergone changes over time. Changes in terms of climate, weather and food availability are the driving forces for this type of natural selection. If shown on a graph, the population bell curve shifts either farther left or farther right, indicating that one trait, is favored over another for a species. An example of this type of natural selection is the beak length of the Galapagos finches, which changed through time due to changes in food availability. Those with larger and deeper beaks survived the scarcity of insects since they were able to crack seeds.

Critical thinking questions: physical anthropology textbook 1. Given that you’ve only just been introduced to the field of physical anthropology, why do you think subjects such as skeletal anatomy, genetics, nonhuman primate behavior, and human evolution are integrated into a discussion of what it means to be human? The study of physical anthropology integrates the subjects of skeletal anatomy, genetics, nonhuman primate behavior, and human evolution because anthropologists look to the fossilized remains of hominins to see what their environments were like and what they ate. In addition to these sub fields, anthropologists look to skeletal anatomy to see any evolutionary change or if the hominin had died from any diseases and how old and tall

Long and medium neck giraffes will be able to get the food, but small neck giraffes are not going to be able to eat. Stabilizing selection means when genetic variation decreases as the population “equalizes” on a particular characteristic. An example for this selection is that there is a community of squirrels, they have to pass into trees and branches to get food. Big

Long, American fingers crossing over 49ers jerseys. Orioles caps plucked from foreheads. A troop of nine year olds in blue speedos impatiently tapping their feet and twisting their legs as a loudspeaker screeches overhead. A celebrity wrapped in a tight red dress, pressing a microphone to the puckered “o” of her lips as her vocal cords strive for new heights. Every Superbowl, every little league game, every hot, heated, and overcrowded band of bottoms squeezed on metal, dented bleachers, Americans, aided by pride and alcohol, bellow the “Star Spangled Banner.”

What you are looking at is the fine result of over 200 thousand years of evolution; the master piece of natural selection, and a perfectly adapted organism to life on earth. • But with exponential grow in technological advances, unpredictable climate change or even space exploration.

The Evolutionism or Creationism Debate The evolutionism-reationism debate has been going on for centuries among christians and scientists. However, creationism is said to have more logical proof of their points being the strongest. According to Charles Darwin, Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin, and it is now regarded as be the main process that brings about evolution.
