Answer:
D. all of the above
Explanation:
Australopithecus (first ape-man): Australopithecus is considered as the connecting link between apes and man as they shared the characteristics of both. The fossil records shows that they appeared around 5 million years ago. <em>Australopithecus africanus</em> was about 1.5 meters high and had human as well as ape like features. It was with bipedal locomotion, omnivorous in their diet and had erect posture. It had human like teeth with small canines and large chewing teeth. The brain was more like an ape with the brain capacity of about 500 cc similar to that of an ape. He lived in caves, had projected brow ridges with no chin. Its believed that <em>Australopithecus africanus</em> gave rise to <em>Homo habilis</em> about 2 million years ago.
The earliest species of Homo genus is <em>Homo habilis</em>. They were skill full man also called as handy man or the tool maker. He had erect posture with bipedal locomotion. The teeth were like modern man. He was skilled and made tools with stones. Slowly with evolution the prognathous face changed to orthognathous in cro magnon (<em>Homo sapiens fossilis</em>).
Bacteria have been found to be able to detoxify certain chemicals; perhaps there are more.
<h3>What is bacteria?</h3>
Bacteria are common, primarily free-living creatures with only occasionally one biological cell. Bacterium is the singular form. They account for a large chunk of the prokaryotic microbial kingdom. The bulk of the ecosystems on Earth are home to bacteria, which are typically a few micrometers long and were among the first life forms to emerge there.
Bacteria can be found in soil, water, acidic hot springs, radioactive waste, and the deep biosphere of the Earth's crust. Bacteria play a crucial role in several stages of the nutrition cycle by recycling nutrients like nitrogen from the atmosphere. The nutrient cycle includes the breakdown of dead bodies; microorganisms are in charge of the putrefaction stage of this process.
