Nor were the ancient relatives of whales that you see pictured on this tree — such as Pakicetus. Hippos likely evolved from a group of anthracotheres about 15 million years ago, the first whales evolved over 50 million years ago, and the ancestors of both these groups were terrestrial. These first whales, such as Pakicetus, were typical land ...
Learn how whales evolved from land-dwelling mammals to fully aquatic creatures over millions of years. Discover the fossil discoveries that revealed the origin and diversity of cetaceans, and how they challenged Darwin's theory of evolution.

10 de may. de 2022 · Whales have a fascinating evolutionary history transitioning from being land-based to wholly aquatic in just eight million years. Specimens are well documented historically because their bodies are easily preserved in ocean sediment and their large size has made them much easier to find and recover for study.
9 de may. de 2022 · A study of 201 whale skulls spanning 50 million years of evolution reveals three major bursts of change in whale diversity and ecology. Learn how whales adapted to water, split into two groups, and refined echolocation.
16 de dic. de 2009 · A new study reveals the coexistence of multiple species of Pakicetus and Attockicetus, two genera of semi-aquatic whales, in freshwater habitats of northern Pakistan. The findings challenge the linear view of whale evolution and suggest a complex radiation of early whales.
