Mr Esquerre said not all evolution was driven by natural selection, but examples such as pythons and boas reinforce its importance in shaping biological diversity. The research focused on the head shape of close to 2,000 specimens in museum collections in Australia and America. Similarly, the extinct Tasmanian Tiger, a marsupial mammal, and the wolf, a placental mammal, evolved similar body plans.Īlthough they look the similar and both constrict their prey, the pythons and boas last shared a common ancestor 70 million years ago in the age of the dinosaurs. Boa constrictors are able to adjust their hunting behaviors according to the density of possible prey items in their habitat. Once the prey is dead, the snake swallows it whole. Instead of injecting poison into its prey, it strikes, grabs and squeezes until the prey is subdued. Hundreds of anaconda images to choose from. Anaconda is the group of four largest non-venomous boa species snakes, found in tropical forest of South America and the green anaconda is the largest snake. Other famous examples of convergent evolution are sharks and dolphins, which are not related but have evolved similar body plans. The boa constrictor is named for its mode of predation: constriction.

Boa constrictors are common household pets which grow no longer than 10 ft, while anacondas are massive snakes which can reach over 30 ft long and are not commonly kept as pets. "If we see that different groups evolve the same things independently when they face the same challenges, we can find predictability in evolution." While both boa constrictors and anacondas belong to the Boidae family, there are important distinctions between them. "The finding of such a strong case of convergent evolution demonstrates the power of natural selection and adaptation in living organisms," said Mr Esquerre from the ANU Research School of Biology. Convergent evolution is where species adapt to the same conditions and evolve similar traits. Lead researcher Damien Esquerre said the study found pythons and boas were an important example of convergent evolution in reptiles. Aquatic pythons look like aquatic boas, burrowing pythons look like borrowing boas and tree-dwelling pythons look like tree-dwelling boas. This happened at least five times in different habitats. The Australian National University (ANU) study found that by living in the same habitat, pythons and boas evolved independently to look similar.

This is because anacondas are the only species of giant boa, while most other boa constrictors top out at 12-18 feet long. On average, pythons are larger than boa constrictors.
