Question

The last common ancestor of humans is

O Pan troglodytes
O Homo neanderthalensis
O Lemuroidea
O Dromaeosaurus​

Answer 1

The last common ancestor of humans is A. Pan troglodytes, also known as the common chimpanzee. Pan troglodytes is the closest living relative to humans, sharing a common ancestor with us about 6 to 8 million years ago.

Humans and chimpanzees have many similarities in their genetic makeup, anatomy, and behavior. For example, both humans and chimpanzees have opposable thumbs, which allow us to grasp objects. We also share a similar immune system and have a high degree of genetic similarity.

Answer 2

The last common ancestor of humans is
`\underline{\textsf{Pan troglodytes.}}`, the common chimpanzee.

Step-by-step explanation:

Homo neanderthalensis, the Neanderthal, is a close relative of humans, but it is not our last common ancestor.

Lemuroidea are lemurs, which are primates that are not closely related to humans.

Dromaeosaurus is a dinosaur that lived millions of years before the first humans evolved.

• The last common ancestor of humans and chimpanzees lived about 6 million years ago in Africa.

It was a small, ape-like creature with a brain about the size of a chimpanzee's brain. Over time, this creature evolved into two separate lineages: one that led to chimpanzees and bonobos, and the other that led to humans.

So the answer is
`\underline{\textsf{Pan troglodytes.}}`
