Are adapids related to lemurs?

The adapids, however, are part of the strepsirrhine dynasty, the group that includes lemurs, lorises and bushbabies.

What did lemurs evolve from?

Instead, they merely resemble ancestral primates. Lemurs are thought to have evolved during the Eocene or earlier, sharing a closest common ancestor with lorises, pottos, and galagos (lorisoids). Fossils from Africa and some tests of nuclear DNA suggest that lemurs made their way to Madagascar between 40 and 52 mya.

Are adapids Euprimates?

The earliest true primates, called “euprimates,” lived about 55 million years ago across what is now North America. Two major fossil euprimate groups existed at this time: the lemur-like adapids and the tarsier-like omomyids.

What are adapids and omomyids?

The adapids were lemur-like primates, while the omomyids closely resembled living tarsiers, but both had forward-oriented eyes and adaptations to life in the trees. This conclusion has caused the scientists involved in the study and the popular media to herald it as a “missing link” that connects us to other primates.

Who are the ancestors of whales and dolphins?

Whale Ancestors Scientists have long known that cetaceans (whales, dolphins, and porpoises) descended from four-footed land mammals. Cetaceans still have some features of land mammals; they use lungs to breathe air and give

How are hippos and whales related to each other?

As embryos, whales have tiny back limbs which disappear before birth. Hippos are the closest living relatives of whales, but they are not the ancestors of whales. Both hippos and whales evolved from four-legged, even-toed, hoofed (ungulate) ancestors that lived on land about 50 million years ago.

When did the first whale appear on Earth?

The first whales appeared 50 million years ago, well after the extinction of the dinosaurs, but well before the appearance of the first humans. Their ancestor is most likely an ancient artiodactyl, i.e. a four-legged, even-toed hoofed (ungulate) land mammal, adapted for running. Cetaceans thus have a common ancestor with modern-day artiodactyls

How are whales related to other land mammals?

Some Modern Whales Whale Ancestors Scientists have long known that cetaceans (whales, dolphins, and porpoises) descended from four-footed land mammals. Cetaceans still have some features of land mammals; they use lungs to breathe air and give birth to young that are nursed by milk produced by the mother.
