suggest two (2) ways that new sources of evidence for evolution can help to corroborate observations that were made by early evolutionary thinkers.

Discussion and Reply to a Statement


Note: Online students, please respond to one (1) of the following three (3) bulleted items.

Using the internet and Strayer databases choose three (3) recent advances in genetics, development, and geology and explain two (2) ways your chosen advances have enriched our understanding of evolution. Next suggest two (2) ways that new sources of evidence for evolution can help to corroborate observations that were made by early evolutionary thinkers.

Read the Science article entitled, “Humans have more primitive hands than chimpanzees” found here. Next provide a brief summary of the article and discuss whether or not you think humans have more primitive or advanced hands than chimpanzees. Justify your response.

Read the Economist article entitled, “Evidence of past tsunamis may indicate the likelihood of future ones” found here then provide a 100-250 word argument for or against the idea that past events will be a predictor of future tsunamis based on what you have learned about fossil evidence.


This week I will be discussing the dynamics of that economists article, “Evidence of past tsunamis may indicate the likelihood of future ones”. Tsunamis are considered disruptions of waterways caused by earthquakes and landslides. These waterway disruptions that create a long high sea wave that can cause catastrophic impacts to dry land shorelines, community and even countries. The great example is the tsunami that happened in December of 2004 that killed over 200,000 people in Asia.

Based on the article, I argue that the idea of past events is a great indicator in a predictor of future tsunamis. Dr. Kelsey and his research crew search for evidence of Pass earthquakes that cause tsunamis in Aceh, which happened several thousand years ago. “To do so they collected cores of sediment from the local sea bed—a dozen in all—from two places close to the modern shore line. As might be expected, given their provenance, a fair amount of each of these cores was composed of sand. Interspersed with the sand, though, were three layers of soil rich in mangrove pollen and in fossils of tiny animals (calledforaminifera, or forams) of species that are commonly found in mangrove forests today.” These findings were a clear indication and evidence that mangrove forest thrived during those times and were destroyed by tsunamis. Further research suggested that the region hand between 11 and 13 tsunami-causing earthquakes that happened in the past a thousand years. I consider it a fact that tsunamis will continue to happen because plate line movement and strain to rock at sea level will alway continue to corrode with time. This means that future tsunamis will continue to thrive and form as the Earth changes.
