The scientific name of the Archaeopteryx is the Urvogel. The Archaeopteryx is also known as the "original bird" or "first bird"

Alligator:
The skeletal/ spine of the alligator is the only structure that relates to the Archaeopteryx. This is organism 1 because there are very similarities.

Flamingo: The exterior features of the flamingo relate to the Archaeopteryx because of the wings and feathers. This is organism 2 because there are more similarities connecting both organism.

Peacock: The exterior and bone structure of the peacock is similar to the Archaeopteryx because the feathers are the same as the Archaeopteryx. Also, the neck structure is the same as the shaped as an s and scrunched up. This is organism 3 because there are many similarities that bring both organisms together.

This tree shows similarities and differences between my fossil and organisms today. For example, my fossil, the Archaeopteryx, relates the the butterfly in the sense that they both have wings. Their wings are special to them because they help them get away from danger, and other obstacles in life. My fossil also relates to the peacock because they both share the same neck bone structure. Their necks are shaped as an “S”, and in more of a scrunched up way.

Claim: Evidence shows that the Archaeopteryx is related to organisms on Earth today.

Evidence:
1(Fossils and Structures) The Ostrich is a living relative that is related to the Archaeopteryx. The ostrich has a similar skull structure as the Archaeopteryx did during the Jurassic period.
2(Embryology) The chicken and the Archaeopteryx both have similar embryo stages. The chickens first stage starts out with a thin tail which slowly starts to get thicker leading into the second stage. Within the last stage, but the chicken and the Archaeopteryx’s tail has developed into feet.
3(Evolutionary Tree) The peacock and the Archaeopteryx are both warm blooded, have feathers, vertebrates, bilateral symmetry, and all of their cells have DNA. This DNA carries on throughout the generations.

Reasoning: Each piece of evidence shows that the Archaeopteryx has similar traits as organisms today. For example, the Ostrich and Archaeopteryx both share a similar skull. The Archaeopteryx used it’s tough skull to break down tough meats and grip its prey easier. On the other hand, the ostrich’s skull is tougher, but doesn’t include the sharp teeth since it only eats smaller things. This shows that the Archaeopteryx is related to the Ostrich because they both have tough, durable skulls. In addition, both the chicken and Archaeopteryx embryo developments are similar. They both start out with small, thin tails that will develop into larger, thicker tails during the second stage. The final stage shows that the tail has separated into two legs for the organisms to walk. Lastly, the peacock and Archaeopteryx are related, because both of the organisms are warm blooded, have feathers to be able to keep warm, vertebrates (backbone and spinal column), bilateral symmetry, and all of their cells have DNA. This DNA is passed on from the Archaeopteryx to the peacock which can also be seen in the DNA/RNA comparisons. The peacock and the Archaeopteryx both share almost identical DNA strands. This evidence proves that the Archaeopteryx is related to organisms today. It can be seen inside and out.

The structure of the Archaeopteryx  skull has changed over time. As you can see in the picture, the bottom skull is the skull of the Archaeopteryx. The skull is longer, and has sharper teeth to be able to grip its prey faster. The middle skull is an image of the Gallus Gallus Domesticus (chicken) has a smaller skull with a sharp beak. The beak is sharper so that the chicken can peck at the grains that it needs to eat. Lastly, present days skull is an image of the Struthio camelus (ostrich) has a small skull with a round tipped beak. This is because ostriches really only eat leaves and seeds. But they will also eat small rodents, snakes, and insects, and their gizzard (specialized muscular stomach) is used to break down the food that they consume.

The organism that is closely related to the archaeopteryx fossil is the chick. The tail of the chick is developing to become feet for the chick. The first development stage shows the tail as a small, sleek tail. The second development stage shows the chick’s tail as thicker, and more durable than shown in the first stage. The last and final stage shows that the chick’s tail has developed into feet for the chicken to be able to walk. Another example to show the development of embryos can be shown through the rabbit. The first development stage shows that the tail of the rabbit is thicker compared to the chicks tail, but it is still thinner. The second development stage shows the tail as thick and muscular. Also, the embryo is starting to grow facial features. The last and final development stage shows that the tail has developed into feet for the rabbit to be able to walk and jump around. Correspondingly, this could mean that the MANX gene, a gene that is a mutation that results in the loss of the tail, could mean that the DNA sequence is suppose to be that way in order for the animal to survive in their natural habitat. Their DNA sequence could be sending a message throughout the body to tell it to change the way the tail is in order to survive in the wild
