In fact ~29% of all orthologous proteins are identical between human and chimpanzee.

Modern humans and Neanderthals also share the FOXP2 gene variant associated with brain development and with speech in modern humans, indicating that Neanderthals may have been able to speak. ", In February 2019, scientists discovered evidence, based on genetics studies using artificial intelligence (AI), that suggest the existence of an unknown human ancestor species, not Neanderthal, Denisovan or human hybrid (like Denny (hybrid hominin)), in the genome of modern humans. Of these 12 supported the Homo-Pan clade, 3 the Homo-Gorilla clade, 4 the Pan-Gorilla clade and 16 gave no resolution. mitochondrial most recent common ancestor, Genetics and archaeogenetics of South Asia, Genetic history of indigenous peoples of the Americas, List of haplogroups of historical and famous figures, "Retroposed elements as archives for the evolutionary history of placental mammals", "A global reference for human genetic variation", "A revised timescale for human evolution based on ancient mitochondrial genomes", "Genomic divergences between humans and other hominoids and the effective population size of the common ancestor of humans and chimpanzees", "Strong male bias drives germline mutation in chimpanzees", "Estimation of primate speciation dates using local molecular clocks", "Likelihood and Bayes estimation of ancestral population sizes in hominoids using data from multiple loci", "Initial sequence of the chimpanzee genome and comparison with the human genome", "When less is more: gene loss as an engine of evolutionary change", "The Evolution of Mammalian Gene Families", "The Role of DNA Insertions in Phenotypic Differentiation between Humans and Other Primates", "Fast-evolving noncoding sequences in the human genome", "A Draft Sequence of the Neandertal Genome", "The genetic structure and history of Africans and African Americans", BBC World News "Africa's genetic secrets unlocked", "The ADH1B Arg47His polymorphism in East Asian populations and expansion of rice domestication in history", "Modeling Recent Human Evolution in Mice by Expression of a Selected EDAR Variant", East Asian Physical Traits Linked to 35,000-Year-Old Mutation, "dbSNP's human build 150 has doubled the amount of RefSNP records!  Another study estimated that 86 genes had been lost. Nature 431:931–945, Joravsky D (1970) The Lysenko affair. The results indicate some breeding between modern humans (Homo sapiens) and Neanderthals (Homo neanderthalensis), as the genomes of non-African humans have 1–4% more in common with Neanderthals than do the genomes of subsaharan Africans.

The internodal time span is useful to estimate the ancestral effective population size of the common ancestor of humans and chimpanzees. Hering, Stuttgart, Graham LR (1977) Political ideology and genetic theory: Russia and Germany in the 1920's. The measures of sequence divergence shown in the table only take the substitutional differences, for example from an A (adenine) to a G (guanine), into account. Only a very tiny fraction of those fixed differences gave rise to the different phenotypes of humans and chimpanzees and finding those is a great challenge. A very important step in the development of human genetics and its application to medicine came with Garrod's demonstration of a Mendelian mode of inheritance in alkaptonuria and other inborn errors of … Genetic data can provide important insights into human evolution.

 Based on the assumption of a constant molecular clock, the study predicts the gene loss occurred relatively recently in human evolution—less than 240 000 years ago, but both the Vindija Neandertal and the high-coverage Denisovan sequence contain the same premature stop codons as modern humans and hence dating should be greater than 750 000 years ago.
 The percentage of nucleotides in the human genome (hg38) that had one-to-one exact matches in the chimpanzee genome (pantro6) was 84.38%. This value is not as high as that from the first study (Takahata), but still much higher than present day effective population size of humans. Nature 426:789–796, International HapMap Consortium (2005) A haplotype map of the human genome. , In March 2019, Chinese scientists reported inserting the human brain-related MCPH1 gene into laboratory rhesus monkeys, resulting in the transgenic monkeys performing better and answering faster on "short-term memory tests involving matching colors and shapes", compared to control non-transgenic monkeys, according to the researchers.
