Early classifications were mostly based on morphological characters like height, shape, color etc. The organisms have evolutionary relationships which were also not considered in earlier classifications.</span>

What do you understand by hominins?</h3>
The term "hominin" refers to a group that includes all living humans, all extinct human species, and all of our direct predecessors (including members of the genera Homo, Australopithecus, Paranthropus, and Ardipithecus). Sahelanthropus, Orrorin, and Ardipithecus are the earliest hominins. Many characteristics that set humans apart from other primates were absent in the ancestors of the human lineage. Sahelanthropus tchadensis from the Chad and Orrorin tugenensis from Kenya are the oldest hominins that are currently known. The skull of Sahelanthropus, which dates to between 6 and 7 mya, is mostly complete, and there are also some additional fragmentary bones.

<h2>Modern Abiogenesis Hypothesis</h2>
Explanation:
- American physicists Harold Urey and Stanley Miller consolidated warm water with water fume, methane, smelling salts, and atomic hydrogen. These beat with electrical releases. These parts were intended to recreate the crude sea, prebiotic air, warmth, and lighting
- After seven days they found that basic natural atoms, for example, amino acids had framed
- Hence the Miller-Urey try effectively delivered atoms from inorganic parts thought to have been available on the prebiotic earth
- Hence, the right answer is "Modern abiogenesis hypothesis is based on Oparin- Haldane theory and Miller- Urey experiment"
