Crested penguins are named after the prominent yellow feathers that are arranged

Question

Crested penguins are named after the prominent yellow feathers that are arranged over the eyes and run along on top of these penguin's heads. Assuming that the feathers are an adaptation, how would biologists explain how crested penguins evolved from an ancestral penguin species without these prominent feathers? Consider the key concepts necessary to explain the evolution of this trait and draft an answer to this question. Then put it aside and revise it for clarity and concision. You can answer this question in 3-4 sentences.

Explanation / Answer

Answer- One of the descendants of the basal Penguin, named by scientists as “Penguin One,” is the ancestor of all penguins that now exist in the world, and it lived some 34.2-47.6 million years ago.Genetic analysis indicate that members of the Spheniscidae family, the present penguins, evolved from non-flying birds and durong evolution , in crested penguins some genes were lost resulting in loss of the prominent feathers.
