Most scientists believe that for half of </span>Earth's<span> 4.6-billion-year history, the</span>atmosphere<span> contained almost no </span>oxygen<span>. Cyanobacteria or blue-green algae became the first microbes to produce </span>oxygen<span> by photosynthesis, perhaps as long ago as 3.5 billion years ago and certainly by 2.7 billion years ago.</span>

It is known that the Earth's orbit around the sun changes shape every 100,000 years. The orbit becomes either more round or more elliptical at these intervals. The shape of the orbit is known as its "eccentricity." A related aspect is the 41,000-year cycle in the tilt of theEarth's axis.
The answer is class and family.
<span>Taxonomic groups are used for biological classification. There are eight main taxonomic groups: domain, kingdom, phylum, class, order, family, genus and species, with the domain as the most inclusive and species as the least inclusive. If we take a look on Mammalia and Hominidae classification, we can assume that Mammalia represents class, and Hominidae represents family:</span>
<span>1. Domain: Eukarya</span>
<span>2. Kingdom: Animalia</span>
<span>3. Phylum: Chordata</span>
<span><u>4. Class: Mammalia</u></span>
<span>5. Order: Primates</span>
<span><u>6. Family: Hominidae</u></span>
<span>7. Genus: Homo</span>
<span>8. Species: Homo sapiens</span>
<span>The migration routes of Homo sapiens reveal
that they went through many environmental and physical challenges but adapted
everything much quickly in comparison to the other animals. The evolution
allowed other species also to adopt these changes but it took them a long time
to fit in the new environment, a sub species of a species adopted the new and
the previous one could not, but Homo sapiens invented ways and tools to combat
and evolve much quickly. It included their living, dietary needs, clothing and
much more.</span>
