He says that “evolution (…) can only be doubted by those who are ignorant of the evidence or are resistant to the evidence. (…) By contrast, the mechanisms that bring evolution about certainly need study and clarification.” Another biologist and geneticist quoted in Moran’s piece is R.C. Lewis. This man has written many papers on the subject of evolution and completely agrees with Moran’s thesis. These are just a few of the credible scientists Laurence Moran utilizes in his essay in order to prove that evolution is indeed a fact.
Max Sharawy Honors Biology Mr. Welch 3-30-14 Recent developments have been made that apply coalescent theory to phylogenetic problems. These developments have initiated the study of the population-level phenomena that started the diversification in anthropoid primates. This has lead researchers to take a new approach when studying primate lineages. The ancestral Ne of certain primate lineages have been very precisely investigated. Researchers have studied some of these lineages have noticed a few things.
Claudia Natalica AP Biology - P.6 Ms. Hicks Key Terms : The Origin of Species and Evolutionary History 1. Adaptive radiation : period of evolutionary change in which groups of organisms form many new species whose adaptations allow them to fill different ecological roles in their communities. 2.Allopatric speciation : the formation of new species in populations that are geographically isolated from one another 3. Analogy : similarity between two species that is due to convergent evolution rather than to descent from a common ancestor with the same trait. 4.
Data and Observations: Create a data table to record your observations and measurements for each skull: Skull|Forehead|Face|Teeth|Foramen Magnum|Brain Cavity |Supraorbital Height (cm)| Pan troglodytes (modern chimpanzee)|Sloping|Flattened|Short/Dull|Rear|6.08cm|54.934cm| Homo sapiens(modern human)|Vertical|Flattened|Short/Dull|Front|9.01cm|67.703cm| Homo erectus(extinct hominid)|Vertical|Vertical|Short/Dull|Front|6.69cm|61.883cm| Australopithecus afarensis (extinct hominid)|Sloping |Vertical|Both/Both|Rear|5.92cm|53.209cm| Unidentified Fossil Skull |Sloping |Flattened|Short/Dull|Rear|6.60cm|51.364cm| Conclusion: I think that the unknown skull holds the most similarities to pan troglodytes. However, the unknown skull is also closely related to the Australopithecus afarensis skull. My hypothesis was right in that the unknown skull was very similar to the Australopithecus afarensis. However, I was a small bit off as the pan troglodytes ended up holding more similarities with the unknown skull. I think that the unknown skull was less
The nature-nurture debate is all about whether genetics (nature) or our environment (nurture) is responsible for our behaviour and development. Early theorists believed that our personality, intellect, behaviour and gender role were determined by our genes and therefore could not be changed. But an increasing amount of evidence has proved these theorists wrong, and our development as an individual is learnt through the environment we live in. One developmental stage of an individual that psychologists have the nature-nurture debate about is the intelligence stage. The nature side of that intelligence is present at birth and we already have a set amount of intelligence.
Summary of “Why Evolution is true” By: Jerry A. Coyne What is evolution; chapter I explains Darwin’s theory of evolution, which applies to all species, new species are descended from earlier forms. This means that organisms with similar characteristics are likely to have shared a common ancestor sometime in the past. The more traits shared by organisms, the closer their evolutionary relationship. This principle of “common descent” explains why anthropologists are interested in studying nonhuman animals, particularly primates (the mammalian order that includes monkeys, apes, and humans), with whom humans share the closest common ancestor. Some of our important human characteristics, such as a spinal cord encased in a bony vertebral column, and the concentration of nerve cells in a brain, are part of our vertebrate heritage, established in a common ancestor over 600 million years ago.
According to author Kenneth Feder, he asserts that “the evolution of modern human being was a geographically broad process, not an event restricted to single region.” In this paper I will examine the two models and give evidence of why the replacement model is a more proficient model to accept as the basis for the evolution of the anatomically modern humans. The replacement model states that from Africa premodern humans evolved into to Homo Sapiens and spread from Africa all the way to Europe and Asia about 100,000 to 200,000 years ago. From modern human migrations out of Africa premodern human beings (Neanderthals) were replaced by a more intelligent and advanced population of anatomically modern human beings. Replacement model asserts that premoderns couldn’t compete with Homo Sapiens, so slowly but surely premoderns became extinct due to the shortage of resources being taken by the more developed Homo Sapiens. Feder suggests that for a time Homo Erectus and Homo Sapiens lived in the same regions as one another but because Homo
Correlation between Ethnicity and the PV92 in Human Genome HeeJin Kang and Misbah A. Pochi Townsend Harris High School Abstract Correlation between Ethnicity and the PV92 in Human Genome In the 19th century, an English naturalist named Charles Darwin suggested a theory that all organisms on Earth descended from a common ancestor. This theory can be supported in many different ways. For instance, phylogenetic tree, also known as an evolutionary tree, shows evolutionary relationships between organisms and the organismal lineages are represented by lines, or branches. These branches show different species, and groups of organisms that are located near a branch are closely related. But all organisms derive from a single strand, which indicates that every living thing has the same origin or ancestry.
Parallel Universes and Alternate Development Gene Roddenberry, the visionary that created Star Trek did not intend for the show to be a pulp series without morals or depth. He intended each and every episode to offer insight to our own societal issues and human experience. The themes of his episodes range from race issues, to environmental awareness, to the morality of expanding technology. The most interesting theme I have found within the Star Trek universe is that of parallel Universes and alternate development of societies similar to our own. These themes are the most interesting because they offer a view of what could have been, or even what could be in our own society, allowing us a level of introspection we could not have imagined on our own.
