[amp_mcq option1=”Palaeozoic” option2=”Pre-Cambrian” option3=”Cenozoic” option4=”Mesozoic” correct=”option3″]<\/p>\n
The correct answer is (c), Cenozoic.<\/p>\n
The Cenozoic Era is the current geological era, and it began 66 million years ago. It is the youngest of the three Phanerozoic Eras, and it is also the longest. The Cenozoic Era is often referred to as the “Age of Mammals” because mammals became the dominant land animals during this time.<\/p>\n
The Cenozoic Era is divided into three periods: the Paleogene, the Neogene, and the Quaternary. The Paleogene Period lasted from 66 to 23 million years ago. The Neogene Period lasted from 23 to 2.6 million years ago. The Quaternary Period is the current period, and it began 2.6 million years ago.<\/p>\n
Humans first appeared during the Quaternary Period. The earliest known human fossils are from the genus Homo, and they date to about 200,000 years ago. Homo sapiens, the species to which modern humans belong, first appeared about 300,000 years ago.<\/p>\n
The other options are incorrect. The Palaeozoic Era lasted from 540 to 252 million years ago. The Pre-Cambrian Era lasted from 4.54 to 540 million years ago. The Mesozoic Era lasted from 252 to 66 million years ago.<\/p>\n","protected":false},"excerpt":{"rendered":"
