PTE Academic Speaking read aloud Life science related sample passages

1.The Human skeleton contains 206 bones. Babies have over 270, but by adulthood many of these have fused together. Some of the main individual bones, and groups of bones, are labelled here. They fall into two groups: the axial skeleton, made up of the bones of the head, spine, ribs, and breastbone; and the appendicular skeleton, containing the bones of the limbs, the pelvis, the shoulder blades, and the collarbones.

2.The discovery challenges the popular belief that the first colonists to North America arrived at the end of the last ice age about 11,500 years ago by crossing a Bering land bridge that connected Siberia to Alaska and northwestern Canada. The earlier date and the location of the woman’s remains on the island adds weight to an alternative theory that some early settlers may have constructed boats and migrated from Asia by sailing down the Pacific coast.

3.Living and extinct human beings and their near-human ancestors are called “hominids” and belong to the Hominidae family of primates. They should not be confused with “hominoids,” which belong to the Hominoidea super family of primates and include apes and humans. Scientists theorize that the human and ape lines branched off from a common ancestor 8 million to 6 million years ago.

4.The story of human evolution began in Africa about six million years ago and it describes the very long process that our ancestors went through to ultimately become modern humans. This process has been uncovered by studying fossils and understanding the underlying theory of evolution, and while new fossils are uncovered every decade revealing new chapters, scientists agree about the basic story.

5.Evolution means the changes that occur in a population over time. In this definition, a “population” means a group of the same species that share a specific location and habitat. Evolutionary changes always occur on the genetic level. In other words, evolution is a process that results in changes that are passed on or inherited from generation to generation. It does not, for example, describe how people can change their muscle mass by lifting weights.

6.Biological evolution explains the way all living things evolved over billions of years from a single common ancestor. This concept is often illustrated by the so-called tree of life. Every branch on the tree represents a species. The fork separating one species from another represents the common ancestor that each pair of species shared. So ultimately, all life is interconnected, but any two species may be separated by millions or even billions of years of evolution.

7.Fossils are the remains or impressions of living things hardened in rock. All living organisms have not been preserved in the fossil record; in fact, most have not because very specific conditions must exist in order to create fossils. Even so, the fossil record provides a fairly good outline of human evolutionary history.

8.The earliest humans were found in Africa, which is where much of human evolution occurred. The fossils of these early hominids, which lived 2 to 6 million years ago, all come from that continent. Most scientists believe early humans migrated out of Africa into Asia between 2 million and 1.7 million years ago, entering Europe some time within the past 1 million years. What follows are some highlights of the early human species that have been identified by scientists to date.
