Why do whales have vestigial skeletal hind legs? Snakes?
Were they designed-in too?
All higher lifeforms are in a constant state of evolution. Consequently none of them are in their final forms. If humans continue to exist they will look vastly different in another 500,000 to one million years. Maybe by that time seals will be completely ocean-dwelling animals.
"This idea of "progression" in evolution is now regarded as misleading, with natural selection having no intrinsic direction and organisms selected for either increased or decreased complexity in response to local environmental conditions.[4] Although there has been an increase in the maximum level of complexity over the history of life, there has always been a large majority of small and simple organisms and the most common level of complexity (the mode) appears to have remained relatively constant."
