Anatomical Features

Anatomical features are features that are the same or close to the same. As time goes by reproduction happens and more variations of animals are being born. Some anatomical features are hair, eye color, what the feet look like, what the ears look like, and maybe height difference. When the parents reproduce young, the young gets features from both features. If the dad is tall and the mom has more fur, so when the young is born it could be tall and the fur of its mom. This is how scientists find out evolution. Evolution is a step by step process which involves organisms over time.

Symbiotic Relationships

A symbiotic relationship occurs when two organisms, individuals or groups of people work together by helping one another with the intent of getting help in return. In a symbiotic relationship, the two people or groups of people live together to provide the greatest benefits to one another.

Colonial organisms benefit from their organization by having more protection or being able to catch larger prey than an individual member could. While this description is usually applied to organisms that live attached to one another, insects, such as honey bees and ants, that live in mutually dependent colonies are also sometimes considered colonial organisms.

Some of the most complex examples of colonial organisms are siphonophores, such as the Portuguese man o' war. They are most closely related to jellyfish and sea anemones, which are true individual organisms. These colonial organisms show a very high level of specialization in their individual members, which are known as zooids.

The Portuguese man o' war has four different types of zooids, each of which performs a particular function for the colonial organisms that the others cannot. One type of zooid provides propulsion for the colony, while another is able to ingest and digest food items. They live attached to one another, sharing nutrition.  (siphonophores.org)            

Anatomical Features

        What are anatomical features? That is a question that a lot of people ask and when they ask it not many people know how to answer. We all need anatomical features. Anatomical features are body parts that are similar in origin, structure, and function; often indicate that two or more species share common ancestors. Examples of anatomical features are human thumbs. They are like bone structures and they are needed for our functions. Animals also have them. Their anatomical features consist of things like webbed feet and other things that are relevant to the species. So the next time that someone asks you what anatomical features are you know the answer.

Anatomical Features

     Anatomical Features is of or relating to the structure of the body. Similarities of Anatomical Features between different kind of organisms Strongly support the theory of common descent. Porpoises, for example, live like large predatory fish, but they resemble to fish. Like all placental mammals, porpoises have lungs and simple jawbones and gestate their young internally. The simplest explanation for these similarities with cats, dogs, and primates is that porpoises are closer related to other mammals than they are to the fish they live among.

     So you know, “fish” like dolphins and porpoises, are called placental mammals. Another example of analogous anatomy across species is the tetrapod limb. The basic form of this structure is a single long bone attached to a shoulder at one end and an elbow at the other. Below the elbow, two small bones are extended to a wrist, it terminated in small bones for toes and fingers. This structure is universal among reptiles, amphibians, mammals. It is unknown among invertebrates.  

Fossils provide solid evidence that organisms from past are not the same as fossils found today. They show a progression of evolution. Scientists calculate the age of fossils a categorize them to determine when organisms lived relative to each other. These are some facts and examples about anatomical features.
