Approximately 4 million years ago, the Earth experienced a cooler climate known as the Pliocene epoch. Global average temperatures during this time were about 2-3 degrees Celsius warmer than pre-industrial levels.
Homo habilis is believed to have lived in Africa approximately 2.4 to 1.4 million years ago.
2 million years ago
The first true mammals appeared on Earth around 200 million years ago, in the late Triassic period. However, these mammals would remain small and relatively insignificant due to the dominance of the dinosaurs. Only when they died out 65 million years ago did mammals grow and diversify to become the ones we see today. The first modern humans (Homo sapiens sapiens) evolved around 200,000 years ago.
No, human beings did not exist during the Mesozoic era. The Mesozoic era, which lasted from about 252 million years ago to 66 million years ago, was dominated by dinosaurs and other prehistoric reptiles. Humans evolved much later, during the Quaternary period, around 2.5 million years ago.
Homo erectus emerged approximately 2 million years ago and became extinct around 100,000 years ago.
From about 180 million years ago until about 65 million years ago.
dinosaurs roamed the earth about 65 million years ago.
they were on earth for more than 1,000,000 years ago
4.567 million years ago
Homo habilis is believed to have lived in Africa approximately 2.4 to 1.4 million years ago.
They dominated the Earth for over 160 million years, from the late Triassic period (about 230 million years ago) until the end of the Cretaceous period (65 million years ago).
200 million years ago the earth was all one large super Continent called Pangaea
They lasted for over 160 million years until they became extinct as a result of the Earth being struck by a meteor about 65 million years ago..
