Explain the development of tetrapod from lobe-finned fish. (Essay Sample)
his paper will require you to access outside research. The DVC library has online links to databases for primary (peer reviewed) literature. Please use Peer Reviewed journal articles unless otherwise instructed. ”
Question 2: In recent years, the Devonian emergence of tetrapods has become a classic case study in Evolutionary Developmental Biology. As Neil Shubin has promoted in Your Inner Fish, the transition from fins to limbs was less dramatic than previous considerations would suggest. Small changes to regulatory genes have proven to have huge impacts on the development of organisms and have led to many of the great leaps of diversification observable in the fossil record. In this paper: -Explain the development of tetrapods from lobe-finned fish -Use the fossil record and genetic information to track homologous traits -Explain how regulatory genes can manipulate already existing traits to create new forms (Evolutionary Developmental Biology) -Consider the environmental (and temporal) context that could have made this new set of traits successful -Highlight some of the early difficulties faced by the first terrestrial tetrapods (atmospheric, dietary, reproductive, etcetera.) Use at least two primary sources to support your work (one can be Your Inner Fish)

Introduction.
A tetrapoda is a superclass of an organism that has four limbs. These animals are direct descendants of a crown tetrapod. Most importantly, tetrapod is clear exemplifications of genetic and taxonomic diversity. This assertion is based on the fact that the organism not only displays a high homology and analogy similarity with other marine life like fishes. Nonetheless, it remains imperative to note that most tetrapods are not only terrestrial but can survive in marine and aquatic environments. However, the naming of a member of the genus tetrapoda has always faced challenges based on the disparity between Linnean and Phylogenetic naming systems. Consequentially, the role of this paper remains with regards to the development of tetrapod from the lobed fish, genetic relationship attached to its traits, the impact of regulatory genes in the evolution of the fish and the effect of environmental factors in the development of the tetrapod.
Explain the development of tetrapod from lobe-finned fish –
The evolution of the tetrapod from the lobed-finned fishes occurred in the Devonian period.
