In recent years, DNA sequences (nucleotide sequence) of mtDNA and Y-chromosomes were considered for the study of human evolution, because
1. | they can be studied from the samples of fossil remains |
2. | they are small and, therefore, easy to study |
3. | they are uniparental in origin and do not take part in recombination |
4. | their structure is known in greater detail |
The most recent and direct pre-historic ancestor is:
