Evolutionary history of life

Cambrian explosion is thought of as the time where organisms on Earth started to diversify and form skeletons that could be fossilized. The development of fossils in early organisms is what gave scientists what they needed to start learning about how life really began to evolve. This event is usually described as a quick process as if the species evolved instantly within a few years. But on the contrary the duration of this incident lasted for about 25 million years (7). The cause of such an…

closest relatives, the chimpanzees? The simple answer is that our brain changed us. But it is how the brain evolved to be so different from all other animal brains that is so extraordinary. The human brain continued to evolve and grow throughout our evolutionary phases. This drastic increase in brain size did not come from chance, adaptations and changes in how and what hominins consumed were leading causes in hominin brain growth. The increase in human brain size is attributed to multiple…

In the emergence of life and consciousness, this whole process can be seen as ontologically contingent on God as an active Creator by virtue of the ontological openness of nature. That is, the fine-tuning of the universe belongs to global ontological contingency in that it is a given nature of this universe with the constants making it suitable for life. Only a small subset of imaginable universes could produce life. Yet the anthropic principle connotes the fundamental…

All life on Earth evolved from a common ancestor, thus creating diversity through morphological differences and unity through shared molecular and genetic makeups. Big Idea 2 says biological systems utilize energy and molecular building blocks to grow, reproduce…

Museum of Natural History is a work of art that thoroughly explains the story of life through evolution. The exhibit begins by informing us about organic compounds coming to be on earth and how all living organisms require organic compounds. It moves on to explain single cell organisms developing from organic compounds and then becoming self-sufficient using energy from the sun. These single-cell organisms grew into more complex beings with genetic variation. Multi-cellular life evolved on the…

1. Gopnik’s primary message in this essay is that anyone can make an impact in history no matter what their background is like. Gopnik’s uses the lives of two notable historical figures, Abraham Lincoln and Charles Darwin, to make his point. Lincoln was born into a poor, uneducated family that lived in a log cabin in the rural woods of Kentucky. Darwin, on the other hand, was born in the English countryside to a family of free thinkers and of wealth. Both came from vastly different backgrounds,…

reproductive strategies that are relative to the reproductive success of each sex. They are learned at a young age, usually in the first few years of life when the mind is most susceptible and malleable to new information. Children learn these strategies through parental influence and through the more modern invention, schools. Schools reinforce evolutionary reproductive strategies through the teacher’s behaviors and teaching styles, the teacher’s expectations of certain behaviors and rewarding…

For many different religions they all have their own theory/purpose as to what life is and how we came to be on this earth. To find out whether our life has any meaning after death or how we were brought onto this earth I will be looking at two different religious groups such as secular humanists and catholics to see what they believe on the existential questions. Question one - Secular Humanists: What happens after death? Secular Humanists believe that when a person dies there can be no…

Anthropological scientific studies have extensively grown within the last 30 years, though; it is still fairly new to understanding the elements of all the different cultures the world has to offer. Colonialism has provided substantial starting point and has acted as a base for anthropologists’ views and concepts. Anthropology and colonialism have always gone hand in hand when examining the beginnings of societies and cultures. Colonialism offers and clear understanding of policy and practices…

interesting women , she discover Eukaryotic cell development revolutionized the modern concept of how life occurred on earth. One of her main theories were natural selection acting on mutations that could develop new adaptations and new species. She showed that a major organizational event in history of life probably involved the merging of two or more lineages through symbiosis. Lynn was evolutionary theorist , taxonomists , bacteriologist , protistology, and botanist. Also accomplished degrees…
