Writing Assignment #1 Lasiognathus dinema
There are a couple misconceptions you might have about evolution and natural selection. The strongest and most important organisms do not survive over the generations. Although evolution occurs due to fitness in an individual or individuals of a species, an organism cannot survive over generations. Fitness is achieved through variations in populations of species through genetic differentiation (Scottville “n.d.”). Since the life cycle of all living organisms is to be born, survive, mate, and die, it is impossible for an organism to live through several generations. The mutation only allows for the organism to be better adapted to the environment it is in through its generation.

2014). Darwin’s theory of evolution focuses on two concepts, the adaptation of organism and natural selection.
According to Darwin in the first edition of The Origins of Species, he explains “decedent with modification” which refers to the different traits that organisms have from their ancestors (Than 2015). The theory explains that all organisms are related. All organisms come from the same ancestor, the differences in appearance derive from genetic mutation that allowed for organisms of the species to adapt to the new environment they lived in and therefore creating new species that differs from its ancestors.
Natural selection occurs when groups with similar traits of the same species are more successful in procreating (Reece et al. 2014). Traits are an important part of natural selection as more favorable traits allow for the survival of the organism. The survival of the organism allows for the it to produce more offspring passing of its heritable traits. The more advantageous traits become dominant, and if the environment allows for the organism’s survival with the trait, over time it can become a new species (Reece et al. …show more content…
The anglerfish genus Lasiognathus are most commonly found in the North Atlantic and central North Pacific Ocean of the Hawaiian Islands (Pietsch and Sutton et. al. 2015). The new species of anglerfish, Lasiognathus dinema was discovered in the Gulf of Mexico at a depth of 800– 1300 m within a 250 km radius of the Macondo wellhead (Pietsch and Sutton et. al. 2015). An ancestral species of the Lasiognathus dinema could have been separated from, its habitat resulting in the introduction of the ancestral specie to the Gulf of Mexico. Traits that allowed the ancestral specie to survive in the new habit were passed off to the offspring through natural selection. The transfer of this traits through genes allowed for the ancestral anglerfish to develop into a new species we now know to be called Lasiognathus dinema. The traits of the Lasiognathus dinema such as the brown appendage could have benefitted the anglerfish by preventing light from reflecting of its appendage allowing for the esca to appear as a small organism that other fish could easily consume. The thread-like prolongations could have evolved in such a way that it appears like organism living in the depths of the Gulf of Mexico. This could have allowed for it to easily catch unsuspecting prey through deception. It is possible that Lasiognathus dinema could have evolved this way,
