It may only be a [madder / matter] of time before dinosaurs are back among us. Biotechnology and [genetically / genetic] engineering company Colossal Biosciences claims it is on the [crisp / cusp] of successfully bringing back extinct species. On Tuesday, the company announced its plan [to / for] resurrect the moa – a 3.6-metre-tall, flightless bird. The giant moa once [roamed / beamed] New Zealand's South Island. It was hunted [for / to] extinction 600 years ago. Colossal's chief scientist Beth Shapiro said: "We're bringing back [canine / avian] dinosaurs." Her colleagues will try to recreate the extinct bird by [excavating / extracting] DNA from the bones of long-[deceased / decreased] moa. Scientists will use this DNA to modify the genome of an emu, which is the closest [living / alive] relative of the moa.

Colossal is [disembarking / embarking] on many "de-extinction" projects. These have created [controversial / controversy] among the scientific community. Colossal [refines / defines] de-extinction as: "The [progress / process] of generating an organism that both [resembling / resembles] and is genetically similar to an extinct species." It claims de-extinction will allow scientists to engineer natural resistances [in / on] endangered animals today. It would also [response / enhance] the adaptability of species to "thrive" amid climate change, [dawdling / dwindling] resources, disease and human interference. However, critics contend [what / that] extinct animals cannot be replicated. Many scientists are concerned about the unforeseen and detrimental impacts of inserting "hybrid" species [into / onto] the wild.
