Are snakes and lizards secretly related: The surprising truth explained

Lizards and snakes may look very different at first. Lizards have legs, eyelids, and ears that you can see. Snakes, on the other hand, have long, limbless bodies and move in a very different way. Many people think they aren't related because of these clear differences. But scientific studies show that the two animals are very closely related in terms of evolution. They are both part of the same larger group of reptiles and share a common ancestor that lived millions of years ago. Understanding this link helps explain why some lizards look snake-like and why both share certain physical traits.Yes, snakes and lizards are very similar. A study in the Encyclopaedia Britannica on how to classify reptiles says that both belong to the same order, Squamata, which includes all reptiles with scales, like snakes and lizards.They have a common evolutionary ancestor because they are in the same order. This means that both groups came from the same reptiles over time.Squamata is the biggest group of reptiles. There are thousands of species in it that live in a wide range of places.According to research published in Encyclopaedia Britannica, members of this group share key features such as:Scientists group lizards and snakes because they have some things in common, even though they look different.Scientists have found proof that snakes came from reptiles that looked like lizards a long time ago.The study published by the Environmental Literacy Council says fossil records and studies of anatomy show that early snake ancestors had features that were similar to lizards, such as small limbs that slowly disappeared over time.This slow change explains how snakes today got their long, limbless bodies.Lizards and snakes have a lot of the same biological traits, even though they look different.Both have scales that protect their bodies and keep them from losing too much water.As they grow, they lose their outer skin on a regular basis. As per Encyclopaedia Britannica, shedding skin is a common thing for reptiles and helps them grow and get rid of parasites.Both are ectothermic, which means they need heat from outside sources to keep their body temperature stable.Their skeletal and muscular systems exhibit significant evolutionary similarities.There are clear differences between the two, even though they are related.LimbsEyelidsEarsOver time, these groups adapted to their environments, leading to these differences.Some lizards have changed over time to look a lot like snakes. People often call these lizards "legless."As per the Encyclopaedia Britannica, some lizard species have lost their limbs over time to adapt to their environment, making them look like snakes.But they are still lizards because they still have things like eyelids and ear openings.Scientists have a better idea of how the connection works thanks to modern genetic research.The Environmental Literacy Council published a study that says DNA analysis shows that snakes and lizards are part of the same evolutionary group and have a common ancestor.This shows that snakes and lizards are not separate species, but are instead closely related in the same family tree.Changes in the environment over millions of years affected how these reptiles evolved.According to the Encyclopaedia Britannica, these changes are the result of natural selection over long periods of time.The connection between snakes and lizards shows how evolution can create very different body shapes from the same starting point. It also explains why scientists group animals by their ancestry instead of just how they look.
