The four types of nitrogen bases of dna nucleotides are:
- Adenine (A)
- Cytosine (C)
- Ganine (G)
- Thymine (T). 
These bases form specific pairs (A with T, and G with C).
<h3>What is DNA nucleotides?</h3>
Nucleotides can be defined as those organic substances consisting of a nucleoside and a phosphate. 
They serve as monomeric units of the nucleic acid polymers – 
- Deoxyribonucleic acid 
- Ribonucleic acid, 
So therefore, the four types of nitrogen bases of dna nucleotides are:
- Adenine (A)
- Cytosine (C)
- Ganine (G)
- Thymine (T).

There have be found some fossils of ancient remains over the years. What the fossils from Atapuerca revealed about the hominins living in Europe at this time is below:
- The Skull is known to show Interbreeding that took place with neandertals and their relatively healthy population.
- The Fragment shows that there was a possibility of cannibalism in that area.
It shows that possible cannibalism took place as there were Cutmarks on various hominin bones found at Atapuerca mirror.
 The relatively healthy population was found out through the study of the dentition of the Atapuerca hominins by anthropologists. It gave them a view into their diet and overall health. 
 The interbreeding with the Neandertals was shown through the Nuclear DNA that was gotten from bones and teeth of bones found at Sima de los Huesos
