Could Scientists Bring the Dodo Bird Back to Life?

The checklist of extinct species that genetic engineering firm Colossal needs to convey again to life is rising. The newest addition: the dodo.

Colossal gave life to real-world visions of Jurassic Park in 2021 with its mission of bringing again the woolly mammoth. In August 2022, the corporate, which has places of work in Boston, Dallas and Austin, Texas, mentioned it additionally deliberate to de-extinct the Australian thylacine, or Tasmanian tiger.

This new mission, introduced Tuesday, would convey again a species that is traditionally highlighted as a case of how people can contribute to the extinction of an animal species.

When did the dodo develop into extinct?
The final dodo was killed in 1681, in response to Portuguese sailors found the dodo on the island of Mauritius, which is off the east coast of Africa within the Indian Ocean, greater than 5 centuries in the past.

The birds, which have been bigger than turkeys, have been killed for meals, the location says. Pigs and different animals delivered to the island ate dodo eggs.

“The dodo is a main instance of a species that grew to become extinct as a result of we – folks – made it unattainable for them to outlive of their native habitat,” mentioned Beth Shapiro, lead paleogeneticist and a member of Colossal’s scientific advisory board, within the announcement.

Shapiro, a professor on the College of California-Santa Cruz, led a gaggle that introduced in March 2022 it had sequenced the dodo genome. “I’m thrilled to collaborate with Colossal and the folks of Mauritius on the de-extinction and eventual re-wilding of the dodo,” she mentioned. “I notably stay up for furthering genetic rescue instruments targeted on birds and avian conservation.”

How are scientists attempting to convey again extinct species just like the woolly mammoth?
Colossal’s biotech and genetic engineering groups are combining woolly mammoth and elephant DNA to recreate a next-generation mammoth able to surviving within the Arctic and serving to restore that ecosystem. “These embryos can be implanted into wholesome feminine elephant surrogates with our first calves anticipated in 5 years,” accounting for the 22-month gestation interval, Ben Lamm, co-founder and CEO of Colossal.

The same course of is getting used with the Tasmanian tiger’s genome and comparable mammal DNA to convey again that predator – exterminated within the early twentieth century – to the island off the southeast tip of Australia.

Colossal is creating an Avian Genomics Group to convey again the dodo and, finally, different extinct fowl species “by means of genetic rescue methods and its de-extinction toolkit,” the corporate mentioned in its announcement. Colossal additionally introduced $150 million in investments, boosting to $225 million its funding because the firm’s September 2021 debut.

What different advantages may Colossal’s analysis yield?

Gene modifying and biotech advances used for de-extinction “will inevitably have utility within the human healthcare subject,” Lamm mentioned. Gene modifying expertise equivalent to CRISPR is already getting used to appropriate genetic mutations present in ailments. “We’ll be constructing new instruments to allow extra complicated modifying protocols which can advance the cutting-edge in comparison to what’s out there within the healthcare trade,” he mentioned.
