The question is incomplete as it does not have the options which are:
A. The threefold change happened in one concentrated burst.
B. The change was not consistent in direction, but happened in multiple bursts concentrated at each speciation event.
C. There was consistent directional selection toward a larger brain all along the lineage between the two species.
D. None of the above.
Answer:
Option-B
Explanation:
The hominids evolved with time and the known hominid in modern time is the Homo sapiens or modern human.
The Homo sapiens like other species could have evolved from the older species through speciation and studies suggest that one of the major factors of human evolution is the size of the brain.
Two possibilities could explain the size of the brain that it could have evolved slowly with time called the gradual equilibrium or in bursts concentrated at each speciation event.
Since the punctuated equilibrium takes place in bursts until the species reach stasis is the most applicable condition for punctuated equilibrium to happen therefore Option-B is the correct answer.
Answer:
The answer is A
Explanation:
Since their variations are best suited for the environment, they have a higher chance of surviving.
Answer:
practice sustainability
Explanation:
If we produce less CO2 by: riding bikes, ride-sharing, walking, public transportation, hybrid vehicles are ways we can decrease pollutants individually. If we promote policies for recycling, proper disposal of hazardous materials, urban agriculture, farmer's markets, and "green energy" we can make an even bigger impact that would decrease detrimental global changes such as warming and ocean acidification. Its interesting to think about how much gas was spent to drive your bananas to your grocery store from where they were produced.
The answer is finger prints, it is because finger prints are
same as epidermal ridges in terms of their pattern characteristic because they
are unique as people’s finger prints are not as the same as other people has in
which, making them unique just like epidermal ridges.
