The fossil discoveries of horses demonstrate the gradual changes in species over time, including the evolution of their skeletal structure and teeth. Early fossils of horses had four toes and shorter teeth for grazing on soft plants. Over time, as the climate and landscape changed, horses evolved to have longer teeth for grazing on tougher plants and fewer toes for greater speed and mobility.

Transitional fossils provide evidence of intermediate forms between species, such as the discovery of the Archaeopteryx fossil. This fossil shows characteristics of both dinosaurs and birds, including teeth, a long bony tail, and feathers. This provides strong evidence that birds evolved from theropod dinosaurs, and that the evolution was a gradual process rather than a sudden transformation.

Similarities in DNA between species suggest common ancestry, as seen in the genetic similarity between humans and chimpanzees. Humans and chimps share over 98% of their DNA, indicating that they share a recent common ancestor. The closer the relationship between two species, the greater the similarity in their DNA, providing evidence for the evolutionary history and branching of the tree of life.

DNA similarities between species suggest common ancestry, as seen when comparing the genomes of birds and fish. While these two groups of animals are very different in appearance and behavior, molecular analysis has shown that they share many genes and biochemical pathways. These similarities suggest that birds and fish share a common ancestor that lived hundreds of millions of years ago.

Antibiotic resistance in bacteria and pesticide resistance in cockroaches demonstrate the process of natural selection. Bacteria that are exposed to antibiotics but have a genetic mutation that allows them to survive will pass on that mutation to their offspring, making the resistance increasingly common in the population. Similarly, cockroaches that are exposed to pesticides but have a genetic adaptation that allows them to survive will pass on that adaptation to their offspring, leading to the spread of pesticide resistance in the cockroach population.

I'm sorry, my previous response was erroneous. Here is the correct one:

Antibiotic resistance in bacteria and pesticide resistance in cockroaches demonstrate the process of natural selection. Cockroaches that are exposed to pesticides but have a genetic adaptation that allows them to survive will pass on that adaptation to their offspring, leading to the spread of pesticide resistance in the cockroach population. Similarly, bacteria that are exposed to antibiotics but create a genetic mutation that allows them to survive will pass on that mutation to their offspring, making the resistance increasingly common in the population.
