¿Qué es la Selección Natural? Básicamente, l a selección natural es el proceso por el cual seres vivos que tienen características que los equipa mejor para adaptarse a presiones ambientales, (tales como depredadores, cambios climáticos y competencia por comida o pareja) tienden a sobrevivir y reproducirse en mayor cantidad que otros de su especie, de tal modo que se asegura la perpetuación de esas características favorables. Para entender bien cómo es que funciona este proceso, tenemos que saber algo de genética ya que la selección tiene sus raíces en esta. Las cuatro leyes básicas de genética (establecidas por Gregorio Mendel), son estas: 1- Las características de un organismo son determinadas por sus genes. 2-Cada organismo tiene dos factores, o alelos, que determinan cada característica en específico. 3-Cada padre contribuye un alelo para su hijo.    4-Los alelos pueden ser dominantes o recesivo. Si existe un alelo dominante, este definirá la característica qu...

¡Hola! Hoy quería compartirles algo que creo que es muy interesante acerca de los niños. En Mateo 18 leemos que Jesús habla con mucha importancia de los niños, ¿no? Por ejemplo él dice "De cierto os digo, que si no os volvéis y os hacéis como niños, no entraréis en el reino de los cielos". (Mateo 18:3) En Mateo 18:4, "Así que cualquiera que se humille como este niño, ése es el mayor en el reino de los cielos." Y más adelante Jesús dice: "Dejad a los niños venir a mí, y no se lo impidáis; porque de los tales es el reino de los cielos."(Mateo 19:14) Wow, ¡aparentemente es gran  cosa ser como un niño para entrar en el reino de los cielos! ¿Porqué sera? Bueno, cuando pienso en un niño, puedo mencionar por lo menos tres características. 1- Su inocente fe. 2- Sus ojos llenos de asombro, maravillados de todo lo que ven. 3- Su felicidad sin preocupación ni ansiedad. Yo tengo un hermanito de 4 años, y les puedo decir que lo que ...

Todo lo que Dios nos da, ¿lo usamos para su gloria?  Piensa en algo que Dios te ha dado. Puede ser un talento o puede ser algo material. Incluso el tiempo es un regalo de parte de Dios.  En mi caso, pienso en mi gusto por la lectura. Disfruto en gran manera leer clásicos, ficción, biografías- simplemente me encanta. Y he pensado, ¿Y porqué no leo la Biblia tan seguido como leo Las Crónicas de Narnia   o El Hobbit, si Dios fue el que me dio el gusto por la lectura? 1 Corintios 10:31 dice " Si, pues, coméis o bebéis, o hacéis otra cosa, hacedlo todo para la gloria de Dios." Colosenses 3:23 " Y todo lo que hagáis, hacedlo de corazón, como para el Señor y no para los hombres" No estoy diciendo que no leas otra cosa más que la Biblia, pero e l gusto por la lectura es un regalo.  Disfrútalo, claro, pero úsalo para la gloria del que te lo dio. Y digo lo mismo para cualquier cosa que tengas, cualquier cosa en la que eres bueno, y cualquier cosa que...

Life is full of desires. Some seem far far away. But is God keeping some things away from us for a reason? So that we look away from what we want, and wonder at the things we do have? God is graceful to us and gives us big treasures that we do not see, Usually because we are focused on the wrong things. Focus on the right things. Focus on God. ;)

For all the young people out there, Wrestling with math? Bored with History? Succumbing under Grammar? I Understand. I've been there. And  I had this question: How will Geometry/ Calculus help me as an adult? What if I never became an engineer or a scientist? You might think I'm crazy but, here's the thing: Algebra is teaching us more than a(b+c) = ab +ac. Really. Math is  teaching us to think. My guess is that most of us will probably never use all of those complicated equations... But with Geometry, we are learning to think deductively. We can train our mind to learn. To fix our attention. Learn what we need for life. Learn from the circumstances and from the people around us. This brings me to "boring" history. I personally love history, it is my favorite subject. But it is more than "In 1492 Columbus sailed the ocean blue". We are looking at men's and women's lives. Their successes and mistakes. We can learn from those mistakes,...

This is a description I wrote for English Class. I hope, it gives away the right connotation: majesty.  T he road to Monterrey extends for miles and miles, until it disappears into the skirts of the great mountains that look upon anything that roams earth with kingly superiority. The Sierra Madre Oriental lines the orange horizon. Because of its height, it appears to be close, but after an hour of travel, it still sits far away. The plains that stand below, at the mercy of the mountains, extend as wings from the road. As guards, dark slender trees with spiny heads stand scattered along the plain among the golden grass. The sun, already hidden from sight, seems to have set the plains beyond on smokeless fire. The flames dissolve into a blue that darkens with altitude until, at last, disappears in the blanket of clouds. And the sky, which carries the flag, crowns the mountains in their glory. 

         In 1997, a project was started to determine the age of our planet Earth, consisting of 8 scientists, who had PhDs in Atmospheric Science, Physics, Geophysics, Geology, and Hebraic and Cognate Studies. This group was titled RATE (Radioisotopes and the Age of the Earth).        "The objective was to gather data commonly ignored or censored by evolutionary standards of dating. The scientists reviewed the assumptions and procedures used in estimating the ages of rocks and fossils. The results of the carbon-14 dating demonstrated serious problems for long geologic ages."*        In various experiments, the samples resulted being dated thousands of years old, not millions as they had been dated by other radiometric dating methods.       "The RATE scientists are convinced that the popular idea attributed to Charles Lyell from nearly two centuries ago, 'the present is the key to the past,' is simply ...

-In the beginning God created the heaven and the earth. (Gen. 1:1) -And God created great whales, and every living creature that moveth, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind: and God saw that it was good.(Gen. 1:21) -And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth. (Gen. 1:26) -So God created man in his own image, in the image of God created he him ; male and female created he them. (Gen. 1:27)

"There is for a free man no occupation more worthy and delightful than to contemplate the beauteous works of nature and honour the infinite wisdom and goodness of GOD." -- John Ray (1660)

1 Give unto the Lord, O ye mighty, give unto the Lord glory and strength. 2 Give unto the Lord the glory due unto his name; worship the Lord int he beauty of holiness.  3 The voice of the Lord is upon the waters: the God of glory thundereth: the lord is upon many waters.  4 The voice of the Lord is powerful; the voice of the Lord is full of majesty . 5 The voice of the Lord breaketh the cedars; yea, the Lord breaketh the cedars of Lebanon...  7 The voice of the Lord divideth the flames of fire.  Psalms 29: 1-5, 7

      "Can it be by accident that all birds, beasts, and men have their right and left side alike shaped (except in their bowels); and just two eyes, and no more, on either side of the face; and just two ears on either side [of] the head; and a nose with two holes; and either two forelegs or two wings or two arms on the shoulders, and two legs on the hips, and no more?                  "Whence arises this uniformity in all their outward  shapes but from the counsel and contrivance of an Author? Whence is it that the eyes of all sort of living creatures are transparent to the very bottom, and the only transparent members int he body, having on the outside a hard transparent skin and within transparent humors, with a crystalline lens in the middle and a pupil before the lens, all of them so finely shaped and fitted for vision that no artist can mend them?              "Did blind ch...
