How is evolution not just 'chance'?

Your answer

Are humans the only species that can learn 'language'? Consider the story of "Kanzi".

What segregates human communication from those of other apes?

1. Some people believe evolution as a chance event whereas others believe it as creationism. Creationist do not believe the point that only chance event has led to all the complexity and diversity of life. Evolution does contains a component of chance but there are non-chance events as well that allow evoltion to occur. Lets understand natural selection with the help of mutations, mutations can be either beneficial or deleterious. The organism with beneficial mutation enjoy an advantage over others and thus are more likely to reproduce and passed on throughout the population. Those with deleterious mutation will not reproduce and thus wil disappear from the populatio. This is nothing but natural selection. It is clear from the above example that natural selection is not just chance.

2 &3. Most primates communicate with smells, sounds, visual messages, and touching. Non-human primates emphasize the use of body language. Human communication is far more focused on the use of oral sounds. Our speech is radically different from the hoots, howls, whistles, barks, slaps on the ground, and other sounds used by non-human primates to communicate. Our languages are complex symbolic systems. That is to say, our words are combinations of sounds to which we arbitrarily assign a specific meaning. Like all symbols, the meaning of words cannot be discerned by listening to the sounds. They must be explained.

Humans are the only primate species that hosts two species of louse: head lice and pubic lice. The sister species of the pubic louse is the gorilla louse. The two lineages diverged 3 or 4 million years ago, when a gorilla louse switched hosts to colonize a hominin host. When the ancestral gorilla louse species speciated into two species (a gorilla louse and a hominin pubic louse), was this allopatric or sympatric speciation? Explain your answer.

a. Not all evolution is adaptive. Chance plays a role in evolution. Genetic drift can mean certain alleles increase in frequency even when they have negative fitness consequences (remember your population modeling simulations). b. Selection varies over space. A trait may be adaptive in some other area but not in the area the organism or population currently resides. c. Selection varies over time. A trait that might have been adaptive in the past may no longer be adaptive. d. Physical...

Because ecological disruption can put native species in contact with humans and livestock, it is believed that an increased number of threatened species in an area leads to a greater risk of novel disease transmission. A team of ecologists is investigating this relationship and records the number of threatened species and the number of novel diseases in different biogeographical regions. The following is their data set: Region. Number of Threatened Species. Number of Novel Diseases. 1 12 20 2. 10...
