The president of the March for Life says next week’s annual event featuring thousands of pro-life activists is celebrating that babies are “unique” from the first moment of conception — as science and technology have revealed.

“As we know, advancements in science and technology really support revealing the humanity of the child in the earliest stages in the womb,” Jeanne Mancini told Breitbart News in a phone interview.

"Being pro-life is not in opposition to science. It’s quite the opposite in fact…technological advancements continue to reaffirm the science behind the pro-life cause" #MarchforLife #Prolife https://t.co/fO6UkiKcJV — Catholic News Agency (@cnalive) January 11, 2019

She explained the reason why the theme of this year’s March for Life — the world’s largest pro-life event — is “Unique from Day One: Pro-Life is Pro-Science.”

“Years ago, the other side claimed developing babies were ‘lifeless blobs of tissue,’” Mancini said. “They don’t even try that anymore. Ultrasound advances allow us to hear and see heartbeats now at six weeks, and a blood test can tell a baby’s sex by seven weeks now.”

“There have also been so many advances in prenatal surgery — just remarkable advances,” she added.

The 46th annual March for Life is taking place on Friday, January 18, in Washington, DC. Each year, the March is held on or about the anniversary of the Supreme Court’s decision in Roe v. Wade, in which the high court invented a right to abortion, though none ever existed in the Constitution:

Abortion is the critical issue of our lifetime, and not just for the obvious reason. Our society is beginning to lose our most foundational common belief. That is, the existence of human rights and inherent human value. #prolife #MarchForLife — Scott Neumann (@ScottNeumann12) January 8, 2019
