Answer:
b) had been created by divine intervention a few thousand years before.
Explanation:
In Darwin’s time, most people assumed that all species were brought into being at the same period or age and it was the usual believe. Therefore, Darwin’s ideas which he got from his voyage brought new understanding to biology.
The Voyage of the Beagle
In 1831, Darwin (22 years old) journeyed for a scientific exposition on the HMS Beagle ship. He observed and collected specimens of plants, animals, rocks, and fossils wherever the expedition was ashore. The Figure attached showed his voyage journey.
Darwin’s Observations
His observations helped him form his theory of evolution. Lets consider:
The great diversity of life.l which was seen in his visit to tropical rainforests and other new habitats where he observed many plants and animals not known to man.
His idea that living things—like Earth’s surface—change over time was from him digging up fossils of gigantic extinct mammals, e.g. the ground sloth proving that organisms differed from their past forms.
Science is based on the feature of "<span>detailed research with reliable sources" among many other things. It is crucial that the tests can be repeated with the same results. </span>
Animals memories are very good especially Dolphins. Dolphins Have Longest Memories in Animal Kingdom. Marine mammals can remember their friends after 20 years apart, study says. Bottlenose dolphins (pictured in the Caribbean) have amazing memories, a new study says. Sorry, elephants: Dolphins have taken the top spot for best memory, at least for now.Aug 6, 2013
Answer:
Los primeros en llegar a tierra no solo ayudaron a alterar los ciclos de nutrientes, sino que también contribuyeron a una de las extinciones masivas de la Tierra. Y a medida que las plantas evolucionaron, también lo hicieron los ríos, creando más hábitats para las cosas verdes y los animales que siguieron.
Explanation:
English: The first arrivals on land not only helped alter nutrient cycles, but contributed to one of Earth's mass extinctions. And as plants evolved, so did rivers, creating more habitats for green things and the animals that followed.
Answer:
Extinction is the natural process by which species die off.
