@chefk the two leaves at the bottom are the cotyledons/ seed leaves. They are the first to appear when the seed sprouts and they do not look like the true leaves, which are all the other ones that appear forever after. Usually the seed leaves drop off after awhile. Yours will eventually too.
@batman. It is not a tomato pepper hybrid. It is a tomato. It is not the cherry tomato you thought you were planting. There can be various explanations for this. If it was a seed you saved, the cherry tomato might have crossed with some other tomato. If it was a commercial seed, sometimes other seeds sneak into a packet. Or it is a seed that was in the soil some other way. Everywhere I put my compost down, I get dozens of tomato seedlings sprouting from seeds that survived the composting process.
The definition of what makes two similar things different species is that they are different enough that they cannot crossbreed. Tomatoes and peppers are both in the nightshade family, but they are different species and cannot (without laboratory help) cross breed.
