Did we start out with Human DNA?
I know that this might be a dumb question but I'm confused as to how the Human DNA came to be. I always thought that the Human DNA is just an amalgamation of all of the genes that we've gathered through evolution but I've been told that we already had Human DNA from the beginning.
If anyone can answer the question, can you also please provide a source of information for me to look into? That would be really great.
Thank you and have a nice day.

The answer is implicit in your question. Our ancestors who didn't have human DNA were not human, and the moment that our ancestors did have human DNA, they were, by definition, human. So, ultimately, your question is about language syntax, not about biology.

Human DNA evolved from ape DNA. Example: chromosome 2 is one of the twenty-three pairs of chromosomes in humans. Humans have only twenty-three pairs of chromosomes, while all other extant members of Hominidae (apes) have twenty-four pairs. Human chromosome 2 is 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 nearly 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.Source(s): https://en.wikipedia.org/wiki/Chromosome_2

Humans were created with human DNA from the beginning.
Chromosome 2 Fusion?Humans have 23 chromosome pairs. Apes have 24. Evolutionists often claim that two smaller chromosomes fused to create human chromosome 2 at some early point in human history. They base this claim on the fact that the banding patterns in two smaller chimpanzee chromosomes are similar to the banding pattern on human chromosome 2. However: The bands actually do not line up perfectly, thus the supposed evidence for the fusion event on human chromosome 2 is in the wrong place. While chromosome fusions have been documented in other species, there are no other examples of two chromosomes joining at the ends. The telomeres help prevent this. If a head-to-head fusion occurred, it should leave behind evidence of the original telomeres, i.e. characteristic repetitive telomere sequence (TTAGGG), in both forwards and backwards direction. There are telomere motifs in this area, but they rarely repeat in a tandem fashion as they would if they were truly telomeric, and they can be found in other parts of the genome as well. Since every chromosome has a centromere, a head-to-head fusion should produce a chromosome with two centromeres. But centromeres have a distinctive repeating sequences of 171 units that are specific for a species. Human Chromosome 2’s supposed vestigial centromere looks nothing like a chimp centromere, but it does match several other places in the non-centromeric human genome. If a head-to-head fusion occurred, there is no way that it happened in the middle of an active gene, for two halves of a single gene would not be found on different chromosomes. Yet the supposed fusion site is located in the middle of a highly expressed and tightly controlled human gene.Considering all this, there is little evidence that human chromosome 2 is the result of an ancient fusion event.

DNA are just instructions for how to grow your body. It's passed from parent to child, so, as all life (plant and animal) is related, much of the instructions are the same.

You got your DNA from your parents. They got their DNA from their parents.

Define "beginning". We are part of a chain of life that stretches back unbroken for billions of years. What point along there are you calling the "start"?
- ZirpLv 75 months ago
Well, yeah, by definition
However, our second largest chromosomes have about the same info on it as two separate pairs of ape-chromosomes, while the other 22 pairs are almost twins of ape-chromosomes. Apparently the apes' 24 pairs became humans' 23 pairs of chromosomes.
How the hell did that happen? It's one of biology's mysteries

There is a gap- a jump in our history. This is still called "the missing link".
Believe what you will, but I will go with the Sumarian texts that Oannes had a hand in it.
You think genetic manipulation of species is a new thing? Have you seen the Egyptian overseers?

we probably did have human dna from the beginning since we're human
