Experimentos de proceso evolutivos

La evolución biológica es un proceso lento y complejo que ha sido estudiado a través de diversas disciplinas como la paleontología, la biología evolutiva y la filosofía. Charles Darwin realizó un estudio seminal sobre la dispersión de semillas, demostrando que estas podían sobrevivir largos periodos en agua marina y germinar posteriormente, sugiriendo que podrían desplazarse grandes distancias mediante corrientes oceánicas o adheridas al barro en las patas de aves.

The first division between continents was made by ancient Greek navigators, who named them 'landmass, terra firma'.

Generally classified by convention rather than any strict criteria, nowadays seven regions are regarded as continents from a geopolitical point of view.

Antarctica is not only the coldest place on Earth but also the highest, driest, windiest and emptiest, completely covered with ice.

75% of the world's ice and 70% of the Earth's fresh water is located here.

Summer months of December to February give 24 hours of light, while the winter months of late March to late September are pitch dark the whole day.

There are no permanent inhabitants, except for scientists maintaining research stations in Antarctica.

There is plenty of animal life in Antarctica. It is a continent of extreme conditions but a range of well-adapted animals thrive here at various times of the year.

Name at least 5 of these animals.

Antarctica sees half a year of light and half a year of complete darkness.
Write down which months give 24 hours of light, and which are the ones that give pitch darkness the whole day.

Write down the temperatures of the Frozen Continent during the summer and the winter.

Experimento de Semillas en el agua

Estudio de Darwin
¿Pero había semillas en el barro? Darwin recogió tres cucharadas de barro de la orilla de un estanque, que mantuvo cubierto en su estudio durante seis meses, registrando cada una de las semillas que germinaban. Y contó en total 537.
Otra posibilidad considerada por Darwin era la dispersión de semillas en el barro de las patas de las aves.
Darwin quería mostrar que las especies pueden dispersarse a distancias mayores de lo que la gente creía. Por eso, probar que las semillas podían sobrevivir durante largos períodos en agua de mar y luego germinar era importante, ya que implicaba que era posible la dispersión a grandes distancias a través de las corrientes oceánicas.

Native Americans have lived along this river and its tributaries for thousands of years. Most were hunter-gatherers, but some formed agricultural societies.

Formed from thick layers of the river's silt deposits, this river's embayment is one of the most fertile regions of the United States; steamboats were widely used in the 19th and early 20th centuries to ship agricultural and industrial goods.

Name this river.

The world's largest freshwater lake by surface area and the third-largest freshwater lake by volume can be found here. It provides a route for the transportation of iron ore, as well as grain and other mined and manufactured materials.

Large cargo vessels called lake freighters, as well as smaller ocean-going freighters, transport these commodities across this lake.

Name this lake.

Australia is the world's smallest continent and is also known as an 'island continent' as it is surrounded by water on all sides.
