History of biology

species with similar niches and limited resources available. A niche is defined as an area that a species inhabits, the role or function of the species in the ecosystem and the species relationship with all is biotic and abiotic factors affecting it (Biology online dictionary, 2015).The limiting resources could be resources such as mates’ nutrients and space (M. Beals, L. Gross, S. Harrell, 1999). Competition exists between species with similar niches and limited resources because they are…

3. Results 3.1. Bumblebees We recorded a total of 98 bumblebee individuals (Bombus sp.) comprising 13 species (Appendix A, Table A.1). Sixty-four individuals belonging to 12 species were identified in managed meadows, and 34 individuals belonging to 8 species in abandoned meadows. Three of the total species were cuckoo bumblebees (Bombus [Psithyrus] sp). Five species were classified as long-tongued and 8 species as short-tongued. Total species richness and number of long-tongued species were…

In your own words describe Darwin's theory of evolution by natural selection. Charles Darwin is given the credit for bringing the theory of evolution is to the mainstream of modern science. this is why the evolution theory is sometimes called “Darwinism”. Charles Darwin was the youngest son of a wealthy physician. most of his life he was a lackluster student. door and dropped out of medical school, and enrolled at Cambridge University to study for the ministry. this was encouraged by his…

Are humans aware of the important role of more than one hundred thousands of genes that we have? I would say not all of us have. This question is not often ask unless we form part of a science club or have careers that are associated with biology, as a college student and future professional woman I do think it is important to ask this type of questions and to know the answer. People always tend to ignore the scientific side of the how our personality, behavior, temperament and experience…

Scientists learn about Earth’s history from rock layers, radiocarbon dating, and relative dating. The first way scientists learn about Earth's layers is by studying rock layers. Scientist discover fossils in different layers in the Earth and draw conclusions to the ones buried in the same layer to get an understanding of what kind of creatures were living in a time period. After studying the layers scientist also develop theories that turn into laws, for example the Law of Superposition states…

From both the article and the textbook, some of the unique qualities of humans are its bipedalism, large brain, complex language, and the ability to forge tools. Of all the traits listed above, bipedalism is one of the most vital. Not only was it essential for the survival and expansion of our species, but according to Darwin it is considered a key force for human evolution. (Ironically enough, one of the major health problems that people face today is living a sedentary life style.) Before we…

Each trust is like a step you must take to protect the animal kingdom. Through these trusts, a human’s cruelty can be transformed into compassion for all living beings. The authors want us to respect the interconnection through all living species. Every day humans harm the natural world more, without realizing the damage they are causing. The purpose of The Ten Trusts is to change your perspective on how we live on this planet. The authors want you to follow these trusts so the natural world…

From the moment we come into this world and take our very first breath, all we’re doing is trying to survive. People survive in other ways such as these: in The Hunger Games, by Suzanne Collins, Peeta Mellark has to use his cake decorating skills and make himself blend in with the mud he’s laying in, in order to escape the other contestants to survive the games. In Ender’s Game, by Orson Scott Card, Ender Wiggin has to go through increasingly difficult games and also has to fight off the buggers…

One of the five agents of microevolution is natural selection. It influences changes in gene frequencies in a population. Natural selection is defined as a process in which there is a competition to pass on genes. In natural selection, some traits are more favoured than other traits. This may result in changes in a population. The favoured traits become more common compared to the traits that are not favoured. The favoured traits are based upon on the environmental conditions. When certain…

However, through the course of this report, more information has been uncovered; research of archive records has uncovered the chain of ownership for the specimen, which has been corroborated through oral history records (see Appendix 1). These records have also provided more information about the creation of the specimen. With these additional records now available and directly connected to the specimen, the authors anticipate that this will improve its level…
