Specifically regarding humans, Chromosome 2 proves that we do in fact share a common ancestor with the Great Apes. All of the Great Apes have 48 chromosomes (24 pairs), we have 46 chromosomes (23 pairs). Where did that pair go? We believed that a chromosome had gotten fused, but we weren't sure. If there was no fused chromosome, then evolution had a huge problem. Then we found Chromosome 2. Chromosomes have a telomere on each end and a centromere in the middle. Each chromosome has two telomeres and one centromere. So if a chromosome had been fused, it would have three telomeres (one on each end and one in the middle) and two centromeres (one should be inactive). Guess what...we found it. Chromosome 2 has three telomeres and two centromeres (unlike any other chromosome). Somewhere along the line, we broke off and took our own evolutionary route, although we still belong in the family of Great Apes.
On a side note, Endogenous Retroviruses (ERVs) exist in DNA. They are essentially viruses that are "good," and they exchange information. If they land on a body cell of an organism, their information is forever lost. However if they land on a sperm or an egg, their information will be passed to that organism's offspring. Chimpanzees and humans have over 60 ERVs in the exact same places in our genome. The chances of even one ERV landing in the same spot in our genomes (if we weren't related) is .00000000016% (since our genome is about 3 billion base pairs long). Think of the likelihood that over 60 ERVs would land in the exact same spots.
Things to study to improve your understanding:
- Summation
- Atavisms
- ERVs
- Vestigial Structures
- Pseudogenes (relates to atavisms)
- Speciation (very important)
- Allele Frequencies
- Genetic Drift

AnswerAlthough many examples are produced, when examined closely, they often could be interpreted differently under another paradigm. Some of the evolutionary arguments for vestigial organs and embryonic recapitulation have turned out to be either fallacious or fraudulent (in the case of the latter). Answer">Answer">AnswerYou believe in micro evolution do you not? If so then you must accept macro evolution as it is micro evolution on a grander scale AnswerThe evidence does not support it... case in point: antibacterial soap... the bacteria are microevolving, but the whole time, they remain bacteria. The DNA information is so specific, (according to Richard Dawkins, equal to 30 sets of the Encyclopedia Brittanica) and ordered in such a way, it has never been observed or proven to occur, in any single celled creature or multi-celled creature.Micro-evolution is not only a part of macro-evolution, it is the same mechanism as macro-evolution. Macro-evolution includes speciation, as a result of continuing micro-evolution.
Serendipitous
Well, theism is the belief in a personal god, and darwinism is darwinian evolution via natural selection, so I imagine theistic Darwinism would be accepting evolution and believing in a personal god at the same time. Christians who accept theistic Darwinism assume that the creation story found in Genesis came about due to macro evolution (i.e. the evolution of one species from another).
In science, a hypothesis and a theory differs in that a hypothesis is a conjecture based on empirical observation or theoretical derivation yet unproven or by any experimental work, and that a theory is a hypothesis that has been rigorously tested by many researchers and supported by strong evidence. Evolution is a theory that has been repeatedly tested, supported by overwhelming evidence, and can be used to explain natural phenomenon very well.
A theory is an idea system with a lot of evidence to support it--for example, the theory of evolution. A law (in science) is an idea system with proof attached to it--no contradictions--example, the law of gravitation.
Micro-evolution is not only a part of macro-evolution, it is the same mechanism as macro-evolution. Macro-evolution includes speciation, as a result of continuing micro-evolution.

Macro evolution is just speciation, so you are a form of macro evolution. We and the chimpanzees have a common ancestor that we split from about 6 million years ago. We became Homo sapiensand they became Pan troglodytes.
Evolution is sometimes described as macro-evolution, which is the long-term evolution of an entire new species, and micro-evolution, which is largely to do with less significant evolutionary changes within a species. Many creationists accept the existence of micro-evolution, but say that macro-evolution does not occur.
Because nothing is proof of evolution.
The fossil record
An example of macro-evolution is the appearance of feathers during the evolution of birds from theropod dinosaurs.

Macro-evolution. Or, more accurately, speciation.
i dunno which is which but they evolve with the kind that is just due to a degrading birth defect or mutation for the worse cuz "evolution" is false!
yes u can tell by looking at him
