How does evolution work

The theory of evolution explains how strands of DNA change. An X-ray, cosmic ray, chemical reaction or similar mechanism can modify a base pair in the DNA strand to create a mutation, and this modification can lead to the creation of a new protein or enzyme. The theory of evolution further proposes that billions of these mutations created all ...

Another type of evidence for evolution is the presence of structures in organisms that share the same basic form. For example, the bones in the appendages of a human, dog, bird, and whale all share the same overall construction (Figure 18.1.6 18.1. 6) resulting from their origin in the appendages of a common ancestor.Department of Biology 4102 Life Sciences Building (LSB) Provo, Utah 84602 801-422-2582 [email protected].

First, they seek to explain the “goodness of fit” of organisms to the environments in which they live. A less fancy way of saying this is that scientists want to explain why organisms seem to be very good at doing what they do.

The most famous way evolution works is natural selection. Some traits make an individual more likely to survive and pass on their genes. Imagine a flock of birds with different heights. The taller birds can reach more food. So, tall birds may survive better and pass on their tall genes to their babies.

Population genetics and evolution takes place on a huge scale, as you know. What this means is that each environmental pressure can be thought of as a variable that lasts hundreds of thousands of years. If the pressure is short and not really that impactful, the evolution will be minimal or non existant.This is one of the forces of evolution. Gene pool: The entire collection of genetic material in a breeding community that can be passed on from one generation to the next. Genetic drift: Random changes in allele frequencies within a population from one generation to the next. This is one of the forces of evolution.18.
