Cladistics

This week, I want to continue on with the discussion on evolution and classification of animals. Today's post will be centered around cladistics. which is an important term to know in the unit of evolution. I will discuss mainly about clades, traits, and cladograms. Clades I have made reference to the idea of evolution several...

Gene Mutation

We have discussed gene mutation before when talking about evolution. Mutation is indeed one of the processes that lead to evolution along with variation, gene flow, non-random mating, etc. Today, we will take a look at types of gene mutation and sickle cell anemia - a disease caused by mutation. Gene Mutation A gene mutation...

Evolution Vocabulary

Evolution is the change in the heritable characteristics of biological populations over generations. There are several vocabularies related to evolution, and I organized some essential words and their definitions.   Word Definition Species A group of similar organisms that can breed and produce fertile offspring Population Group of individuals of the same species that live...

The Five Processes of Evolution

Centuries ago, Charles Darwin proposed the idea that all species share a common ancestor, and the DNA of living organisms changed over time. At that time, this theory was not approved by scientists as religion was an essential part of society. However, nowadays, the theory of evolution is one that appears commonly in websites, textbooks,...

Human Heredity

Human heredity is about how humans traits are passed on through generations. Several vocabulary words are related to the topic of human heredities, such as alleles, genotype, and variation. However, some of these words can be highly confusing and challenging. For example, it might be difficult to differentiate between alleles and genes. Thus, today, we...

The History of DNA

DNA. You probably would have heard this word at least once. It is one of the most commonly discussed topics in fields such as biology and chemistry. In other words, DNA is very significant, especially because it exists in every single one of our cells. Just like the cells that we've discussed before, it took...
