Question

would a hominin evolutionary tree look thin and spindly or full and bushy?
the hominin evolutionary tree would look thin and spindly because it started only 2 mya and followed a straight linear progression from homo rudolfensis to homo sapiens.
the hominin evolutionary tree would look full and bushy because is started only 2 mya and has many branches between homo habilis to homo sapiens.
the hominin evolutionary tree would look full and bushy because it would have started about 6 mya with multiple branched branches throughout the millennia.
the hominin evolutionary tree would look thin and spindly because it started about 6 mya and followed a straight linear progression from sahelanthropus tchadensis to homo sapiens.

Explanation:

Hominin evolution began around 6 million years ago (mya). Evolution is not a simple linear progression. There were multiple hominin species that co - existed and evolved in different ways over time. This would lead to a complex evolutionary tree with many branches (like a full and bushy tree) rather than a simple linear one (thin and spindly).

• The first option is incorrect because hominin evolution did not start 2 mya and is not a simple linear progression from Homo rudolfensis.
• The second option is incorrect as hominin evolution started around 6 mya, not 2 mya.
• The fourth option is incorrect because hominin evolution is not a straight linear progression.

Answer:

The hominin evolutionary tree would look full and bushy because it would have started about 6 mya with multiple branched branches throughout the millennia.
