小学二年级·胚胎发育学(Embryology)
2011-03-17
“蛋在断崖之上孵着,孵着孵着掉下来了……( Humpty Dumpty sat on a wall, Humpty Dumpty had a great fall…)”娃儿二年级的科学课,就在这首《矮胖子》 变了调的童谣里开始了——胚胎发育学,从一颗鸡蛋说起。三月的第一个星期, 宾夕法尼亚 “山林”州 蒙哥马利 “巨人山”小学从附近农场预定了一打受精鸡胚,每两位学生合孵一个,放进恒温100o F/38o C、恒湿60%的培育箱里,足不出户就能模拟母鸡孵蛋的奇迹。教室内外张灯结彩,贴满“欢迎鸡胚孵化”的横幅,娃儿的笔记本上用各色彩笔工整地记录着:第3天头部心脏形成,第4天消化道与神经系统,第5天脸和鼻,第6天嘴眼腿翼,第9天各部分基本完成,第15天羽毛与脚指甲成形,第21天——小鸡孵化。
孵化期间,娃儿每天至少两次亲手为鸡蛋“翻身”:清洗双手,将蛋轻轻放在手心,顺时针转三圈,逆时针再转三周,再轻轻放回培育箱。他一点不敢怠慢,生怕胚胎与蛋膜粘连,生怕温度不匀让宝宝们受委屈。周末过后,12个鸡蛋里有11个争先恐后地破壳而出,浑身湿漉漉的,毫不客气地闯进这个世界。娃儿激动得两眼放光,赶紧拿起笔,将胚膜、胚乳、卵黄、气胞、卵带一一描到作业本上,标清每个名称的功能。随后对准4只“男婴”、7只“女娃”涂鸦半天——醉眼迷瞪的、好奇观望的、微笑讨喜的,鸡宝宝个个啄着他笔头上的阳光,米色偏淡橙的羽毛,一片一片地闪耀出光泽。
我站在教室门边,看着他小心翼翼地捧起其中一只小鸡,让它站在自己掌心里——那只小小的、还没干透的绒毛球,正用它细得几乎看不见的脚趾,在他的生命线上留下第一个属于别物的重量。那一刻我忽然觉得,他记下的那些天数和器官名称,都会在未来的考试里被逐渐遗忘;但他会一直记得,曾有一个春天的早晨,一只湿漉漉的小生命从他手心里抬起头来,用它还不太能聚焦的黑眼睛,看了他一下。那种被一个崭新生命短暂信任过的感觉,会比任何课本都更长久地留在他的身体里——不是作为知识,而是作为一种微微发热的、关于“开始”的记忆。
