Horns are usually present only in males but in some species, females too may possess horns.

Why did animals evolve tusks?

The different kinds of teeth animals have evolved tell scientists about the pressures those animals faced that could have produced those teeth. Animals with tusks might use them for fighting or for rooting in the ground, exposing them to little injuries that would be risky for enamel teeth that don’t grow continuously.

Why did animals change?

Biologists believe that new species evolve from existing species by a process called natural selection. Organisms that inherit that favorable new gene are likely to become more abundant than others of the species. Sometimes the population of a species becomes separated into two areas, by geography or by climate.

How humans affect animals evolution?

Are humans inadvertently driving evolution in other species? Mounting evidence suggests activities such as commercial fishing, angling and hunting, along with the use of pesticides and antibiotics, are leading to dramatic evolutionary changes.
