Genes are short sections of DNA that determine an animal’s traits—everything from coat color and claw strength to body shape and health. But sometimes, these genes mutate. And while the word itself sounds alarming, most mutations are harmless and invisible.

The more noticeable ones, however, can produce features that are quite rare for the species.

To give you a sense of how these fascinating genetic quirks show up in nature, we’ve put together a gallery of animals — from cats and mice to crabs, penguins, and beyond — each displaying traits that make them stand out from their peers.

    To understand mutations, we need to know more about DNA. DNA is a long molecule composed of building blocks called nucleotides. Each nucleotide is built around one of four different subunits, called bases.

    These bases are known as guanine, cytosine, adenine, and thymine. A gene carries information in the sequence of its nucleotides, similar to how a sentence carries information in the sequence of its letters.

    One type of mutation is a change to a base. This is called a point mutation, and it is like changing a letter in a word.

    ADVERTISEMENT

    Genes carry instructions for making proteins, and when a base is changed in a gene, different results are possible depending on which base is altered and what it is changed into.

    The gene may produce an altered protein, it may produce no protein, or it may even produce the usual protein.

    Another type of mutation is a chromosomal mutation. Chromosomes, located in the cell nucleus, are tiny threadlike structures that carry genes. A chromosome consists of a molecule of DNA and proteins. During these mutations, a long segment of DNA may be inserted into a chromosome, deleted from a chromosome, flipped around within a chromosome, duplicated, or moved from one chromosome to another. Such changes are usually very harmful.

    Mutations can be inherited or acquired later in life. Those that an individual inherits from their parents are called hereditary mutations. They are present in all body cells and can be passed down to the next generation.

    ADVERTISEMENT

    Some mutations are beneficial and increase the likelihood that an organism will thrive and, therefore, pass them on to its descendants. When mutations improve survival or reproduction, the process of natural selection causes them to become more common over time. When mutations are harmful, they become less common over time. In this way, mutations contribute to driving evolution.

    Researchers at the Wellcome Sanger Institute analyzed how quickly mutations occur in species with different life expectancies. They looked at DNA from a cat, black-and-white colobus, dog, ferret, giraffe, horse, human, lion, mouse, naked mole rat, rabbit, rat, ring-tailed lemur, and a tiger.

    The study, published in the journal Nature, showed that mice go through nearly 800 mutations a year during their short lives, which last just under four years.

    It also found that the longer animals live, the fewer mutations they accumulate each year.

    Dogs have around 249 annual mutations, lions 160, and giraffes 99. Humans average 47.

    One of the researchers, Dr. Alex Cagan, said the pattern was "striking" and it was "really surprising and exciting" that all the animals in the study converged on "about 3,200" mutations across their lifetime.

    "Despite having different lifespans, at the end of life the mammals had the same number of mutations," Cagan explained to the BBC.

    "This is the number, but what does it mean? It's a mystery to us," he said.

    I Was Very Fortunate To Spot This White Eastern Gray Squirrel In Highlands North Carolina

    The white squirrel is actually a genetic anomaly due to a mutated gene from the common Eastern gray squirrel. It is called leucism, which is a condition characterized by reduced pigmentation in animals caused by a recessive allele. Unlike albinism, it is a reduction of all types of skin pigment, not just melanin.
