Answer:
Mammals
Birds
Explanation:
The Organs which perform same function and looks but they are different in their structure from each other are called as analogous organs.
Organs are the structures that made up of two or more tissues organized to carry out a particular function.
An organ or bone that appears in different animals with same function is called homologous structure.
Homologous organs have similar origin n basic structure but perform different functions in different organisms. Analogous organs are different in basic structure but perform same functions.
Different animals have bones that appear very similar in form or function and seem to be related.
Examples
The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar sharing common traits.
The forelimbs of all mammals have the same basic bone structure.The structures are similar because they evolved to do the same job. For example, the wings of bats and birds.

Out of the choices given, the excerpt that best reflects Byron's appreciation of beauty was "the nameless grace/Which waves in every raven tress." The excerpt comes from the poem "She Walks in Beauty."
During 66 mya in the Paleocene scientists believe the first primates may have evolved.
<h3>
Evolution of Primates</h3>
- Most likely, a small, nocturnal, insectivorous animal that gave rise to the first primates. The closest extant cousins of primates are tree shrews and colugos, also referred to as flying lemurs.
- The tree shrew is cited as a living example of what the ancestors of primates, or the earliest primates, would have looked like.
- The most ancient ape discovered by reliable fossil evidence is Dryomomys. Only isolated teeth and jaw fragments from Purgatorius, the earliest known primate, which dates back 65 million years, are known.
- In the primate suborder Strepsirhini, the Eocene primates split into two groups at an early stage: the omomyids and the adapids, collectively known as the prosimians.
