Explanation:
A carp (a kind of fish) has 104 and a rattlesnake fern has 184. Most likely neither of these is as complicated as we are (especially the fern).
These kinds of differences are out there because the number of chromosomes doesn’t have anything to do with how complicated or “advanced” a living thing is. What matters is what is on them.
Your fewer chromosomes have the set of instructions for making you and a potato’s chromosomes have the set of instructions for making a potato plant. It doesn’t matter how many pieces those instructions are cut up into.
Think about it like comparing the instructions for building a car to the instructions for building a bicycle.
Let’s say the car’s instructions are in one big book but the bicycle’s instructions are spread over five books. Making a bicycle isn’t more complicated than a car just because it is in five books instead of one. Same thing with your chromosomes and a potato’s chromosomes.
It also doesn’t always have to do with how many “pages” or even sets of instructions are in something’s chromosomes.
