what came first the chicken or the egg

Answers

Answer 1

Answer:

The egg because without the egg the chicken would be non existed

Explanation:

Answer 2

Eggs come from chickens and chickens come from eggs: that’s the basis of this ancient riddle. But eggs – which are just female sex cells – evolved more than a billion years ago, whereas chickens have been around for just 10,000 years. So the riddle is easily solved…or is it?

Taken at face value, there is no doubt that the egg came before the chicken. We tend to think of eggs as the shelled orbs laid by birds from which their chicks hatch – unless we eat them first. But all sexually reproducing species make eggs (the specialised female sex cells). That’s 99.99 per cent of all eukaryotic life – meaning organisms that have cells with a nucleus, so all animals and plants, and everything but the simplest life forms.

We don’t know for sure when sex evolved but it could have been as much as 2 billion years ago, and certainly more than 1 billion. Even the specialised sort of eggs laid by birds, with their tough outer membrane, evolved more than 300 million years ago.

As for chickens, they came into being much later. They are domesticated animals, so evolved as the result of humans purposefully selecting the least aggressive wild birds and letting them breed. This seems to have happened in several places independently, starting around 10,000 years ago.

The wild ancestor of chickens is generally agreed to be a tropical bird still living in the forests of Southeast Asia called the red junglefowl –  with other junglefowl species possibly adding to the genetic mix. From these origins, humans have carried chickens around the world over the past two millennia or more.

So, eggs dramatically predate chickens. But to be fair to the spirit of the riddle, we should also consider whether a chicken’s egg predates a chicken. As humans consistently chose the tamest red junglefowls and bred them together, the genetic makeup of the resulting birds will have shifted. At some stage during this domestication process the red junglefowl (Gallus gallus) evolved into a new subspecies, Gallus gallus domesticus, AKA the chicken.

In practice, it is impossible to pinpoint the moment when this happened. But in theory, at some point two junglefowl bred and their offspring was genetically different enough from the species of its parents to be classified as a chicken. This chicken would have developed within a junglefowl egg and only produced the very first chicken’s egg on reaching maturity. Looked at this way, the chicken came first.

how did jeffersons stance on indian removal change over time?

Answers

Answer:

Thomas Jefferson believed Native American peoples to be a noble race[1] who were "in body and mind equal to the white man, and were endowed with an innate moral sense and a marked capacity for reason. Nevertheless, he believed that Native Americans were culturally and technologically inferior.Like many contemporaries, he believed that Indian lands should be taken over by white people.

Explanation:

Jefferson never removed any Native Americans. However, in private letters he did suggest various ideas for removing tribes from enclaves in the East to their own new lands in lands west of the Mississippi. Indian Removal was passed by Congress in 1831, long after he died. Before and during his presidency, Jefferson discussed the need for respect, brotherhood, and trade with the Native Americans, and he initially believed that forcing them to adopt European-style agriculture and modes of living would allow them to quickly "progress" from "savagery" to "civilization". Beginning in 1803, Jefferson's private letters show increasing support for the idea of removal. Jefferson maintained that Indians had land "to spare" and, he thought, would willingly exchange it for guaranteed supplies of food and equipment.

Las problemáticas de los siglos XX y XXI en México han generado conflictos sociales entre los propios individuos de la sociedad, pues esto ocasiona que se rompa el tejido social. ¿Cuáles son esos problemas?

Answers

La respuesta correcta para esta pregunta abierta es la siguiente.

Las problemáticas de los siglos XX y XXI en México han generado conflictos sociales entre los propios individuos de la sociedad, pues esto ocasiona que se rompa el tejido social. ¿Cuáles son esos problemas?

A lo largo de esos dos siglos, México ha sufrido una serie de sucesos y acontecimientos que lo han marcado hasta el día de hoy.

Después del movimiento de Independencia que culmina con la entrada victoriosa del ejército Trigarante con Agustín de Iturbide al frente, México tuvo los clásicos problemas que tienen lo nuevos países independientes. Un vacío de poder, pugnas internas entre diversas facciones que buscan sus propios intereses, y un descuido por atender las verdaderas necesidades de la población, entre ellos, la de los indígenas.

Con la llegada al poder de Benito Juárez se instituyen una serie de Reformas que buscan modernizar la vida del país, pero el proceso no fue fácil.

Vendría un segundo movimiento que causaría mucha pena y dolor en México. Después de más de 30 años en el poder, la Revolución Mexicana saca al dictador Porfirio Díaz y se vuelve a confrontar el país en otra guerra nacional. Figuras como Pancho Villa, Emiliano Zapata, Venustiano Carranza y otros, luchan por devolver la justicia a los pobres.

Después de la Revolución, la pobreza y la desigualdad se mantuvieron. Y hubo una tercera confrontación, la guerra Cristera.

El cacicazgo del Partido Nacional Revolucionario que posteriormente se convertiría en Partido Revolucionario Institucional (PRI) empobreció más al país por medio del control de los sindicatos y las organizaciones populares.

Aunado a eso, la política liberal impuesta desde la época del Presidente Miguel de la Madrid en 1982, y consolidada por el Presidente Carlos Salinas, llevaron a México a la desigualdad total y la pobreza del campesino y el trabajador Mexicano.

Por esa razón llega al poder el Presidente Andrés Manuel López Obrado, quien trata de implementa una política social más justa, a pesar de que sus rivales de la Derecha le obstaculizan todas sus propuestas.

La realidad es que su popularidad crece un la mayoría de Mexicanos confía en lo que está haciendo.
