Why does this recent discovery about the galapagos finches prove that it’s often challenging for scientists to determine when tw

34kurt

Because the species of finches on the Galápagos island have various appearances but still mate with other finches and produce fertile offspring making it is difficult for scientists to distinguish between two groups of individuals as separate species.

<h3>What is the island of Galápagos?</h3>

The Pacific Ocean island of Galápagos is located to the west of Ecuador. It is a volcanic island known for its diverse and endemic types of living things.

<h3>Why is it difficult to find new species in Finches?</h3>

Charles Darwin spent several years studying the many species of finches on the Galápagos island. He saw a great deal of variation in these finches, which supports the hypothesis of natural selection.

However. it is challenging for scientists to discern between two separate species because the species of finches on the Galápagos island have a variety of features that are different but still mate with other finches and produce fertile offspring.

What could a scientist do to determine what era the Eocene Period belongs to on the geologic time scale?

Burka [1]

Answer:

Option B) study information related to the Cenozoic era

Explanation:

The complete question is

Scientists discovered that the Eocene time period existed in Earths history around 34 MYA. What do they need to do to determine what time period Eocene belongs to on the geologic time scale?

A) learn what happened during Precambrian time

B) study information related to the Cenozoic era

C) view the timing of events in the Mesozoic era

D) research events that happened during the Paleozoic era

Solution -

The period of Eocene belong to the Cenozoic era. The Cenozoic era is divided into three periods-

a) The Paleogene – Existed between 65.5 to 23.03 million years ago

b) The Neogene - Existed between 23.03 to 2.6 million years ago

c) The Quaternary – Started some 2.6 million years ago and is continuing till present

The Paleogene is subdivided into three epochs –

A) The Paleocene – existed between 65.5 to 55.8 million years ago

B) The Eocene – existed between 55.8 to 33.9 million years ago and

C) The Oligocene – existed between 33.9 to 23.03 million years ago

Hence, studying about Cenozoic era will give information about the Eocene epoch

Hence, option B is correct
