PRESENTACION

Sean bienvenidas y bienvenidos al curso de Sistemática I, materia obligatoria dentro del Plan de Estudios de la Carrera de Biología. Algunas de las preguntas que la Sistemática busca responder son: cómo surgió en el tiempo y espacio, y por qué tenemos la biodiversidad actual en nuestro planeta. Asimismo, busca encontrar los patrones de cambio en ancestros y descendientes que ha producido la evolución. Busca también, organizar, nombrar y comunicar procesos y relaciones evolutivas de una forma clara, lógica y accesible para toda la comunidad científica, así como para cualquier persona interesada en el estudio de la biodiversidad.

Siendo la primera materia del Plan de Estudios de Biología que los introduce en el mundo de la Biología, los profesores nos comprometemos a guiarlos para descubrir y zambullirse en una ciencia diferente, un universo donde nosotros mismos junto con todo lo que está vivo en el planeta, somos el objeto de estudio; un universo donde otras ciencias se integran para reconstruir y responder a preguntas como las mencionadas anteriormente.

Para que todo esto camine sobre ruedas, el compromiso tiene que ser de ambas partes, por lo que pedimos su cooperación para que nos permitan ayudarlos y guiarlos en este maravilloso aprendizaje. Requerimos de su comprensión y muchas ganas de aprender. Les pedimos que nos ayuden preguntando, leyendo, escribiendo, y haciendo lo que se requiere en clase para que adquieran los conocimientos necesarios y se apasionen por la Biología. Sobre todo, estimados alumnos, que vengan con gusto y no por obligación. Les ofrecemos una clase amena y en donde el respeto mutuo y comunicación es fundamental.

Finalmente, queremos decirles que entendemos que estos son tiempos difíciles, para unos más que para otros, pero esperamos que la empatía y comprensión entre sus compañeros y compañeras nuca falte. La pandemia nos ha obligado a ver una parte del mundo, que, aunque obvia, no nos habíamos parado a analizar. Queremos que se cuiden mucho, que estén en contacto constante con nosotros y si requieren algún tipo de apoyo, acudan a la página de la facultad. Existen diversas formas en las que podemos apoyarlos.

Les recomendamos que de vez en cuando, entren a la siguiente página. Allí encontrarán varios enlaces de ayuda para mejorar la salud mental y física: https://sites.google.com/ciencias.unam.mx/covid19-fc/home

Las clases se llevarán a cabo mediante la plataforma Google meet o Zoom

Todo lo relevante a la clase y asignaciones (tareas, ejercicios) se hará mediante la plataforma Google Classroom.
