Platypus Genome Could Reveal Details On Evolution Of Mammals

Washington (dbTechno) - Scientists are still extremely curious about the duck-billed platypus, as it is one unique species to say the least. They are apparently a bit closer to understanding it though as they have revealed its genome sequence which could reveal more on the evolution of mammals.

An international team of researchers have released the genome sequence of the Ornithorhynchus anatinus, allowing them to compare the duck-billed platypus to normal mammals.

They found that the platypus genome has roughly the same number of protein-coding genes compared to other mammals.

It also has around 80% of the genes other mammals have as well.

There were some key differences found though, such as genes which allowed it to act like a reptile, shooting venom.

The platypus is extremely unique as it is a mammal that lays eggs, but also has a bill similar to a bird, and venom it can shoot out, similar to a snake reptile.

Francis Collins, director of the National Human Genome Research Institute stated “At first glance, the platypus appears as if it was the result of an evolutionary accident.”

He states this is not the case though, as it is “priceless for understanding how fundamental mammalian biological processes have evolved.”

It is believed that after they analyze the platypus genome could give information into the history and evolution of mammals.

The findings of the researchers have been published in this week’s issue of the journal Nature.
