Instead, responding to their environment, the cells negotiate and feel their way toward a final form. A fertilized egg divides, and divides again, creating a hollow ball of cells called a blastula; genes instruct these cells to release chemicals, and other cells, reacting to those chemical concentrations, decide to migrate elsewhere or to develop into specific types of tissue. Other influences\u2014oxygen, nutrients, hormones, sometimes toxins\u2014further shape gestation. <a href="https://www.newyorker.com/magazine/2021/05/10/persuading-the-body-to-regenerate-its-limbs?utm_source=nl&utm_brand=tny&utm_mailing=TNY_Daily_050821&utm_campaign=aud-dev&utm_medium=email&bxid=5bd678d924c17c104801f684&cndid=40835928&hasha=1dc6f15a30be2d4712fae5f0e5a9a679&hashb=5e4befc88214fadc869224d7cb34d55f51451bc7&hashc=0c6ef6b7bc8221288e1f4a4ca0116d78a21ebdbe47949488640c7c54c93120fb&esrc=AUTO_PRINT&utm_term=TNY_Daily" target="_blank">https://www.newyorker.com/magazine/2021/05/10/persuading-the-body-to-regenerate-its-limbs?utm_source=nl&utm_brand=tny&utm_mailing=TNY_Daily_050821&utm_campaign=aud-dev&utm_medium=email&bxid=5bd678d924c17c104801f684&cndid=40835928&hasha=1dc6f15a30be2d4712fae5f0e5a9a679&hashb=5e4befc88214fadc869224d7cb34d55f51451bc7&hashc=0c6ef6b7bc8221288e1f4a4ca0116d78a21ebdbe47949488640c7c54c93120fb&esrc=AUTO_PRINT&utm_term=TNY_Daily</a><span style="font-family:Calibri,sans-serif"><u></u><u></u></span></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">First, note the reliance on psychological terms.
