Beak

known observations is his observation of the galapagos finches. When Darwin observed the finches he realized they were all similar but some had different wing colors or different beaks. The finches all had beaks that suited the type of food on their respective island. Some had beaks better for holding fruit while other beaks were better for grabbing insects. Eventually Darwin figured out that all of the finches came from a…

Natural selection can be seen as a force, and evolution as a result. Natural selection can be broken down into three concepts that require it to operate. The first is the constant struggle a species face for survival, which results in the continuation of the successful branches of the species, as the others become extinct. The second requirement is a varying population, these more successful branches only stem from mutated groups or individuals whose features become beneficial when faced with…

their home/ environment based on their beak , and talons. For example a ground finch would have a large beak meant to easily break into nuts and seeds on the ground. While, a tree finch would have a sharp pointed beak like a spear that can pierce through bark and grab worms . If one of these two types of birds were to switch their environment it would die young. To explain, the ground finch wouldn't be able to eat the worms within the tree do to its large beak forcing it to die of hunger. This…

Adaptive Radiation and Species Diversification Through a common ancestor, species diverge into new populations which eventually adapt to their new environments and evolve to become their own sub species and then distinct species. This occurs through the process of adaptive radiation. The population of an ancestor species radiates outwards to different ecological niches. From there, these now separate populations adapt to their new habitats and resources in isolation. This gives them…

“If you peck me with that little beak one more time, you’ll go to bed with no dinner again! Understand?” says Mother Sparrow firmly. Snappy nods gratefully; she is weak and hungry, but at least she has learned a valuable lesson. Imagine for a moment that the carefully constructed nest…

The giant squid has eluded scientist since its discovery with nothing but pictures and carcasses to go off of. Its deep-sea habitat makes it difficult to study. The first photo of a live squid was not taken until 2004 and the first live giant squid to be brought to the surface was not until 2006. The giant squid belongs to the phylum Mollusca, class Cephalopada, genus Architeuthis, and species Architeuthis dux. Giant squids are similar to their smaller relatives in many ways including, using…

In today’s society, many people have good educational background however the usage of words sometimes did not match up to an individual’s knowledge. This can be seen using the word theory, especially in evolutionary theory. People usually refer to a theory as a guess and fact as the truth. However, according to the National Academy of Science, a theory is “a plausible or scientifically acceptable, well-substantiated explanation of some aspect of the natural world; an organized system of…

background. The light colored mice were unable to blend into the background. But they started to evolve so they blended and matched the background and it was more difficult for predators to find them. Better beak, Means better chance of survival The different types of Finches have different types of beaks cause they eat different types of seeds, A Finch that has trouble picking…

The Theory of Evolution is well known. As a theory it is not a set fact, but a hypothesis supported by a large amount of evidence, and is widely accepted. But there are still many who oppose it with their substitute being Intelligent Design. Evolution is the theory that traits are selected through natural selection, and that the more successful individuals will have more offspring and pass their unique trait down. The idea of Intelligent Design is that all species were created by an intelligent…

ZO3017-Gerhand Schlosser Student Name: Claudia Speight Student Id: 13402132 The role of Modularity is important in evolutionary development The role of modularity is important in the developmental repatterning in evolutionary development. Organisms are composed of modules which are units of elements. Developmental modules serve as building blocks for evolution. They can been seen in heterotopy, heterochrony, heterometry, loss of modules and redeployment of modules. Here we will see…
