The evidence strongly supports the concept that chromosome II is the head-to-head fusion of two great ape chromosomes. Since we split from chimpanzees it appears that 24 pairs of chromosomes in the great ape linage became 23 pairs. The genes are very similar and do very similar things. There is telomere material in the center of this chromosome and there are two centromere sites, though one is inactive. This shows quite well are common ancestry with the great apes.

What is the evidence for human evolution?
There is much evidence for a transition of hominid forms from an ape-like state to a human-like state in the form of Australopithecus, Ardipithecus, Orrorin, Sahelanthropus, Paranthropus fossils and of course the fossils of early Homo species such as Homo erectus, Homo habilis, Homo neanderthalensis, Homo floresiensis, Homo ergaster, Homo heidelbergensis, Homo antecessor..... There is also evidence from a fused chromosome: chromosome 2. Chimpanzees and Gorillas have 24 pairs of chromosomes and Humans have 23 pairs of chromosomes. The hypothesis was made that one of the chromosomes should have become fused in the line that lead from the chimpanzee-human common ancestor to humans themselves. And indeed, a fused chromosome was found, supporting that hypothesis. Comparative genetics confirms the relationship between humans and their ape relations. By comparative genetics, Darwin's prediction is confirmed (Darwin used comparative morphology) that Humans are most closely related to African apes (chimpanzees and gorillas) and more distantly related to Orangutans. The ape tree of life has been confirmed.
Which early hominid was probably not a direct ancestor of modern humans?
Australopithecus robustus is thought to be a side branch of human evolution, not a direct ancestor of modern humans. They existed around 2-1 million years ago, but their lineage is not believed to have contributed to the evolution of Homo sapiens.
What is the goal anthropology?
The goals for anthropology research include (1) describing and analyzing the biological evolution of human (2) describing and assessing the cultural development of our species (3) describing, explaining, and analyzing present-day human cultural similarities and differences (4) describing and explaining human biological diversity today.
What are two types of anthropology?
Two types of anthropology are cultural anthropology, which explores diverse cultural practices and beliefs of human societies, and physical (biological) anthropology, which studies human biology, evolution, and primates.
What scientists study past and present day human beings?
1. Historians - Scientists who study and write, studying written work of the past. 2. Anthropologists - Scientists who study culture of the past and civilization. 3. Archaeologist - Scholars that study the remains within the earth.
What chromosome belongs to a normal human female?
2 X !
How many copies of chromosome does the human body cope?
2
How many chromosome does a human body have?
Most have 2. Some have 3 :-(
What can evolution be supported by?
Observation, Fossil evidence, Molecular Evidence (Comparing DNA and proteins) etc.Human chromosome 2 is widely accepted to be a result of an end-to-end fusion of two ancestral chromosomes.EVIDENCE:The correspondence of chromosome 2 to two ape chromosomes. The closest human relative, the chimpanzee, has near-identical DNA sequences to human chromosome 2, but they are found in two separate chromosomes. The same is true of the more distant gorilla and orangutan.The presence of a vestigial centromere. Normally a chromosome has just one centromere, but in chromosome 2 there are remnants of a second centromere.The presence of vestigial telomeres. These are normally found only at the ends of a chromosome, but in chromosome 2 there are additional telomere sequences in the middle.Chromosome 2 presents very strong evidence in favour of the common descent of humans and other apes. According to researcher J. W. IJdo, "We conclude that the locus cloned in cosmids c8.1 and c29B is the relic of an ancient telomere-telomere fusion and marks the point at which two ancestral ape chromosomes fused to give rise to human chromosome 2."That's just one of thousands!
Name the 2 human gametes and tell their chromosome number?
The human gametes are Male gametes are sperm and female gametes are eggs. And the gametes chromosome numbers are 42.
What determine the sex of a human being?
Whether they have 2 X chromosomes= girl, of one X chromosome and one Y chromosome= boy
In human which sex chromosome determines if an offspring is a male or female?
In humans, which sex chromosome determines if an offspring is a male or female?
What are the name of 23 chromosomes in human body?
No, there are 46 chromosomes in one cell. A gamete, or sex cell, has 23 chromosomes because during fertilization, the female and male gametes (egg and sperm, respectively) come together to form a new cell with 46 chromosomes
How many chromosome 7 s are there in the human nucleus?
Two, one from each parent. Over 90,000 genes are found on each chromosome and are mostly responsible for protein productions.
A human cell with 2 Barr bodies and no Y chromosome is from?
The human cell is most likely from a female individual. Barr bodies are inactivated X chromosomes in females, and the absence of a Y chromosome indicates that the individual does not have male sex chromosomes.
What determines the sex of a human?
Whether they have 2 X chromosomes= girl, of one X chromosome and one Y chromosome= boy
