Summary Introduction
Introduction:
Hox genes are originated in very early in animal evolution. Development biologist have hypothesized the variations of the Hox genes are responsible for formation of new body patterns in animals. Hox genes are forms proteins that encode and specify the characteristics of ‘position’ ensuring that the correct places of the body have the correct structures. Increases in number of Hox genes have been instrumental in the evolution and

- Use the scenario to answer the question. Scientists have found one new fossil that is similar to Archaeopteryx. It is only the second fossil of its kind. It shows an animal that had a long-feathered tail and small teeth, like non-avian dinosaurs. But the animal also had flight feathers and wings, like modern birds. The fossil also shows a fused clavicle bone, which confirms the relationship between birds and dinosaurs because they are the only two groups with this characteristic, What is true about this scenario? It shows evidence of evolution. It shows evidence of causation. It shows evidence of climate change. It shows evidence of widespread expression.arrow_forwardWhat are Hox Genes and how to they contribute to the creation of a variety of animal body morphology? Describe Phylum Porifera.

The evolution of the swim bladder from the airbreathing organ (a simple lung) of an ancestral fish is anexample of(A) exaptation.(B) changes in Hox gene expression.(C) paedomorphosis.(D) adaptive radiationarrow_forwardBipedalism has many selective advantages. However, there is one disadvantage to walking on two feet: giving birth to an offspring with a large head through a small pelvic opening, which is necessitated by an upright posture, is very difficult. This situation results in a high percentage of deaths (for mother and child) during birth compared to primates. How do you explain the selection of a trait that is both positive and negative?arrow_forward
